*A quiet **Generater.Systems** , love the dual fuel capabilities, camper is 50 amp but the adapter helps and found it still handles the load. Haven't taken a camping trip yet, that's in a couple of weeks. Will see how well it does over a long weekend.*

According the the distributor, they are the exact same unit. The only difference is the color of the plastic.

[@Redfour5]

Beat me to it. So, I'm thinking differences are within a set of acceptable parameters

[@GeneratorReviews]

I hope you guys liked this comparison, I was also surprised by the results I thought the Cummins and Westinghouse would have similar output I have zero affiliations with either brands so my test are none biased. I still think both Gens are Awesome 👍🏾

[@chtomlin]

I don't think you can assume this based on just 2 units.

[@stevemaloney8799]

They are the exact same unit. Westinghouse makes the Onan. My guess is you didn't run the onan in efficiency mode like you did the westinghouse.

[@stevemaloney8799]

When in the efficiency mode they won't handle as much load as when in normal operation.

[@GeneratorReviews]

@@stevemaloney8799 I ran both in eco mode

[@YukonHawk1]

@@GeneratorReviews My under standing of eco mode is that when there is a call for more power the genny will ramp up until demand is met then kick back down. Correct?

[@dynamicaccuracy7398]

I have been an electrician for over 20 years and therefor have to agree with Randy Hunt’s comment. The fact that the Cummins did NOT shut down on overload or even light the overload light when running beyond its power rating and feeding constant 38.8 amps through a receptacle rated for 30 amps is very dangerous for damaging the generator or RV cables connected to it. I definitely would not want a generator that did not shut down when running in an overload condition. If an RV had a 50 amp plug and I needed more power I would buy a bigger generator. So the Westinghouse is the clear winner in my mind because it’s safety mechanisms are working properly. That being said, it appears that either Cummins or Westinghouse is making both of those generators for both brands. I’d bet whichever one actually makes it turns around and sells it to the other brand so they can put their badge on it because physically both generators are identical in every way

[@GeneratorReviews]

Thanks You’re right it should have triggered a over load light and shut down

[@NavinJohnson_thethird]

It could be that particular generator is faulty from the factory and the same could happen to a Westinghouse. I've seen choke issues with the Westinghouse so I'm wondering if there have been choke issues with the Onan.

[@travispelfrey8940]

That’s exactly correct. Onan does not make that gen. We outsource it to Westinghouse and slap our plastic and stickers on it. All warranty work even gets paid by Westinghouse and failed units get sent to them. That’s why there is a price difference. Onan has to make money somehow. Haha.

[@andyo.593]

Either brands do not make their own generators. If you dig inside the generator you will find a Chinese factory stamp. They come from the same Chinese factory and Cummins and Westinghouse just private labels them. The box even says made in China.

[@ericnortan9012]

Agree. I'm an electrician also.

[@thecalledout7]

I just bought a Cummins. They just dropped it off today. Cant wait to go home and check it out. Thanks for rhis video!

[@campingalan]

This is a great comparison for 2 "like" units! Due to price, I would always default to the Westinghouse, if choosing between these two. Our trailer will only be a 30amp rig with 1a/c, so I definitely don't need the inverter coverage above what the generator is rated at. But....it will be interesting in the out years to see if that Onan/Cummins inverter proves to outlast what appears to be the slightly less capable Westinghouse inverter. Have a great weekend all !!

[@randyhunt1581]

It may be a good thing that the Westinghouse shut down so that it actually protected it from damaging the internals. For the Cummings not to shut off when overloaded shows it's safety features are not all working properly. Just a thought that you may want to look into to get these questions answered. Westinghouse is a good brand. Maybe a service history from repairs made on these units would help. I don't know just think all possibilities should be considered. Good video.

@@GeneratorReviews nice review it just have a few questions 😀 I live in Wisconsin we have very cold winters and snow how do you protect your generator from the weather and is it cold and snow proof from your experience? Also, I live in the city I’m trying to figure out how to have a safety plan for when the power goes out for a few days. Back in 1976 the city was shut down for two weeks I was thinking about going with a Delta 2500 and a 2000 gas generator Winston to charge the Delta instead of solar panels due to the snow and bad weather I ccan charge it in my garage. After watching this review maybe just get a bigger unit and put in the woodshed if there’s an emergency what’s your thought? Amazing channel I just subscribed thank you🎉🎉🎉 The champion actually sounded smoother running then the Winston if that’s what it’s called I can’t remember😂

[@GeneratorReviews]

Hey J Moon thanks for the Sub😎 you can use the Delta and recharge it with the generator but that leaves you with out power when recharging it . The Westinghouse 4500w would need a rain and snow cover I’m working on a video about that should be uploading it soon. If you have space for the larger Generator It would definitely be less of a headache and more power than recharging with solar or the 2k Gen. I would also recommend checking out a dual fuel generator for your backup power Gas/Propane. Let me know what you think 🤔 Thanks 🙏🏾

these are literally the exact same generators. the onan did not shut off in overload which is not surprising. they are both made in the same chinese factory just different color packaging and decals. we have the westinghouse version, $200 cheaper because of the name. i would be highly concerned with the overload protection NOT protecting the internals on the onan.

[@randybobandy9828]

While I agree that dual fuel/propane is better for emergency power since you can store propane indefinitely vs gas which expires in 9months to 1 year and maybe 2 years if it's non ethanol/has sta-bil. But my issue is the cost. You only get about 55-60%of the total energy output per gallon of propane vs. gas, which makes it a lot more expensive to run. Yes, propane is slightly cheaper than gas, but the loss in energy output makes it still a good amount more expensive. Basically I would only run propane as a back up energy source and use gas as much as I could.

[@BKD70]

I just don't understand this love for Dual Fuel/Propane. Yeah, no issues with storage, I get that. But Propane makes less power, you burn more of it, and is such a hassle to refuel/refill when the tank goes empty... definitely not worth the extra hassle in my opinion. I'll take gas any day. All you have to do is drain the carb bowl if you're not going to use it for a while... it's not difficult. Use a good stabilizer, fill the tank full, and drain the carb bowl, and you're set for storage.

[@tubemember21]

Right before you started up the microwave for the Westinghouse, your RV was pulling 23.6 amps. When you started up the microwave on the Onan it was only pulling 22.3 amps. That's an extra amp that may have put the Westinghouse over the load and couldn't handle the surge. Good comparison but I'd like to see if done maybe 3 times to see if it behaved the same way.

I bought the Cummins a few months ago and it’s been fine. About 60hrs on it now , had the a/c running in the trailer last week all day 32 degrees c it was fine . The guy we were camping with had a firman 3000w and that thing keep shutting off and running rough ( probably getting to hot and vapour locking I would imagine) . Remote start is handy, the power switch needs to be on but it doesn’t drain the battery overnight. Worth it I think, but time will tell I guess.

[@Tom-In-Ga]

Both generators are identical (except for cosmetics) and made in either China or Vietnam. Have to allow for manufacturing differences. Lets use a car as an example. 2 cars with the exact same specs and options. Yet one will outperform the other. Why? Maybe torque settings were a little higher on one. Or one used parts from Mexico vs Canada vs USA. To me, both generators are winners but I'm not crazy how the voltage dipped on the Cummins brand and kept running. Leads me to think that it was not adjusted properly at the factory. I'd worry that low of a voltage can damage whatever appliances or devices are being used, especially anything with a motor. However, I would never use the genny to that high output. Have to keep in mind that this is a demonstration which, by the way, was excellent!

[@GeneratorReviews]

Thanks for watching Well said you are correct that both Gens are identical but settings on both could be changed by either manufacturer

[@farmer8957]

Hey thanks for the REAL world test of them two ! Also that screen that controls you rv is to cool!

[@tomsmythe4903]

Load was a bit higher (about 2 Amps) on the Westinghouse than on the Cummins. Also, voltage dropped more on the Westinghouse than the Cummins. Leads me to believe the SurgeGuard unit disconnected power from the Westinghouse vs the Westinghouse faulting into overload protection (never saw an overload condition on the Westinghouse). Both units are the same. Conditions were almost the same (battery charging had reduced by the time the Cummins was hooked up). The variable is the SurgeGuard unit which would drop the connection vs allow a sub 105V connection to remain active from shore power. The Westinghouse dropped below that threshold, the Cummins did not. Now, that said, Westinghouse support sucks. Campingworld/Cummins support should be much better. You get what you pay for.

[@GeneratorReviews]

Excellent comment my friend but the Surge Guard did not drop power I ran this test three time and same result on each test the W.H 38.8 amps C.O 40 amps.

[@stevebastin9982]

Big microwave but you can set the power level on it

[@stevebastin9982]

Again no DB levels

[@randybobandy9828]

No the voltage drop was the same, if you're referring to the moment that the gen overloaded and it dropped down significantly that's nothing because it shut down. The Westinghouse house shut down properly instead of maintaining a low 103v. I know I would rather have my gen power off vs running things at a 103v which is potentially harmful to your electronics.

[@yours8601]

The fact that the breaker on the Onan did not trip scares the hell out of me. I will take safety over amount of power anytime. I think I'll be buying Westinghouse.

No problem. Thanks for tip, I will do that next time

[@MrNightro]

The Westinghouse is actually the winner here since it protected the connected loads from a significant voltage drop of 12.5% (nominal voltage was 120 volts while the Onan dropped to 105 volts, Percentage of decrease = |120 - 105|/120 = 15/120 = 0.125 = 12.5% ). The NEC (National Electrical Code) allows for a maximum of a 3% voltage drop ( as per NEC 210.19(A)(1) for branch circuits, NEC 215.2(A)(4) for feeder circuits & a maximum of 1.5% drop on sensitive electronic equipment as per NEC 647.4(D)) on any circuit, so the Onan fell well outside of this requirement.

[@GeneratorReviews]

Well said!! I would have to agree with you. Thanks for watching 👍🏾

[@waynetaylor2231]

Noticed the Cummins voltage dropped down to 103 volts under max load. If I’m correct under 114 volts is bad for your circuits. I feel it should have tripped as well.

[@reelfinatic9439]

Both are well known name, and if your a history buff then you are aware that Westinghouse name is a piece of historical Americana. To this day and history they made everything from industrial broilers to typerwriters and contributed in both world wars. Then there is Cummins and mostly everyone has heard of that brand. Both are great name as far as products go. I was going to pickup a champion 4650 but today I'm ordering the Westinghouse 4500 instead. Plus from various sources the Westinghouse was reported to being the quietest. For my purposes I can sacrifice a little power for more stealth.

[@GeneratorReviews]

Thanks Erik! I liked the history info and thanks for watching.

[@randybobandy9828]

Is Westinghouse really a known name when it comes to generators? I mean I haven't seen their generators before the past few years. I know Westinghouse has been around for over a century and they have made many household appliances, I even had a shitty low budget 32lcd 720p TV from them in 2006 lol. Paid $800 for it and that was considered a STEAL for that size in 2006! Wild. I just feel like their generators are just like any other cheap chinese knockoff brand and considering they are identical to Cummings confirms that. I just can't believe Cummings is willing to put their name on a cheap clone engine like that. Their diesel motors are know for their longevity.

Great video Gavin. I believe I put my comment under someone else comment. But anyway I mention how close in the numbers this two generator where in comparison.

[@livinganewdream3682]

Nice job on the comparison. I think you're right the Cummins unit does a better job. The Westinghouse unit dropped out too quickly. The line voltage on the Cummins sagged to 103v, but that's OK. The amps will climb and could pop a breaker, but you shouldn't damaging anything. Any device that is damaged due to low line voltage is a pretty bad product anyway. I've been designing eletronic systems for more than 25 years and I've seen some pretty bad stuff go into production, but generally most EEs do a good job of protecting their device designs against low voltages at the circuit level.

[@GeneratorReviews]

Hey Thanks 🙏🏾 Most people see 104v voltage drop and panic but it’s okay like you said the amps will increase and trip the breaker to protect the circuit from damage That’s why I always use a good surge protector with low voltage protection just in case

[@brianallen0826]

I'm no expert, but I thought you want a generator to shut off as fast as possible in a overload situation

[@BKD70]

I'd rather see the gen cut off rather than have it try to carry that overload and ultimately overheat a component and let the magic smoke out of something expensive like the inverter or even the PMA (Permanent Magnet Alternator.. the component that actually produces the electricity). Holding that severe overload is a false benefit that could cost you big.

[@livinganewdream3682]

@@BKD70 Only if they have designed in sufficient engineering design margin. I design electronics for a living and typically we report user specs that are 20% under the max load designed use. That means, If I tell you it can do 4500w, then the unit was designed 20% over that to account for tolerances in components during manufacturing. So, the number published to the user is the real use number. No need for you to add in your own margin.

I appreciate the video but I'm not sure I agree the Onan is a "clear winner". Personally I feel the Westinghouse is the winner in this case. The Onan continued to power in a low voltage condition, around 105. This is well outside the states specifications. The Westinghouse disconnected the load and went into overload once the load exceeded the rated specs. This is exactly what should happen.

[@GeneratorReviews]

I agree with you! It was just really close but I know you guys love a good Battle and someone gotta Win. 38.9 to 39.9 but the top end low voltage was low. Thanks for watching buddy 👍🏾

[@TheJonboy713]

Hey, I appreciate everything you do, but I would like to humbly point out, that an experiment is not valid if it is not repeatable, anomalies happen with electricity, and I would say it just because the surge protector killed the first unit prematurely. It may have sustained the voltage in a second run. Much like when your trip a breaker and you go back and turn it on and continue doing exactly what you were doing before and it doesn’t trip again. I wonder if you ran the Onan first if it would’ve tripped the surge protector, and then in the second round on Westinghouse could’ve ran. Just my thoughts and question. Thanks again for the great video!

[@madweazl]

I'm not sure how anyone would come to the conclusion that one was better than the other when the difference in performance was about 2-3%. This would certainly be within margins of error and product variation from unit to unit. With equivalent warranties, it would be nice to know how said warranties would be handled (though I suspect they go to the same place for work/customer service).

[@randybobandy9828]

I mean they are identical units and were probably built right next to each other in the same factory. Price is what I would be more concerned with vs warranty. Part wouldn't matter because you could use parts from either unit.

[@rpbonnette]

So if I’m understanding what happened, it was that your SurgeGuard shut off power to the RV when the Westinghouse voltage dropped below the 103v threshold whereas the Onan never dropped below 103v during the full one minute test with the microwave running. Is that a fair assessment of what occurred. In essence the Westinghouse produced less voltage when placed under full load, while the Onan produced just a bit more voltage under the same conditions.

[@BKD70]

Great point! I'd rather see the gen cut off at that overload rather than try to pull that severe overload and end up frying the inverter or the generator itself.

[@bateslabel]

I don't know if its a better inverter or the Onan allows for the generator to run out of spec more. The Westinghouse kicked off at 38 amps, which it is suppose to. I would be interested in seeing if they each have the same inverter. I also don't think the Cummins makes a dual fuel version, which to me is a must have. That's a nice RV :-)

[@GeneratorReviews]

After retesting several times the Onan kicks off at 40 amps I had to test it after and it would kick off at 40 amps every time and the Westinghouse at 38.8 amps Thanks buddy 👍🏾

[@GeneratorReviews]

That extra 1.2 amps will make a difference

[@randybobandy9828]

Exactly, the Onan ran at a higher amp but at the cost of undervolting @104v. I wouldn't want that. NEC states that 114v is the lowest acceptable voltage, and 108v is the lowest you can get down to before potential damage. Idk it might not matter since most of the time nobody will be running their generator at 100%+ for a extended period of time but imo I would rather my generator power off before running at such a low voltage for more than a few seconds .

[@MrThisIsMeToo]

They are exactly the same, down to every nut and bolt. Just the paint is different. There are videos on KZbin of people who work and repair these generators everyday stating such.

Hi Gavin looking for a generator for the house and or for camping. It’s become overwhelming with what’s out there you’re the man that seen most of them .what do you recommend 3600 to 4000. What’s your best bang for the buck model you would recommend duo fuel , remote start. Great videos by the way definitely a fan.

[@GeneratorReviews]

Thanks I would definitely recommend you watching my next duel fuel comparison video coming up 4500 DF Generator

[@jeffchase9096]

It kind of looks like the charger draw was higher when you first started the tests on the westinghouse (280w before starting fridge,) and by the time you switched to the Onan, it had dropped to 150w, and was using 290w with the fridge on. (Were house batteries near full charge and finished charging while on the Westinghouse?) There might not actually be a true champion if the loads weren't exactly the same. The westinghouse cut off at 38.8 Amps, but the Onan never hit 38.8.

[@wyliesdiesels4169]

a surge protector is the wrong thing to use if the voltage gets too low aka a brown out. it will not shut off if the voltage is too low. what you need is an AVR- automatic voltage regulator. a surge protector is for stopping voltage spikes aka surges EDIT: i looked at the model you have. it has low voltage shutoff which is a feature of AVRs not a surge protection feature....

[@GeneratorReviews]

Hey Wylie Thanks for watching

[@armondk1]

Same exact machines. Safety switch just activated faster. 2 other machines would in all probability react different as well.

[@djwilson48625]

Agreed. A good follow up video would be a de-casing and proving what we know, and that is that they are the same machine. Even better yet, 2 of the same "brand" side by side.

[@billo1656]

I don't know if you had the eco mode on the Westinghouse if that made any difference? I would be concerned that the unit ran in an overload condition without shutting down.

[@stevenludwig3429]

I'll take the Westinghouse because it shut down and protected against low voltage.

[@GeneratorReviews]

The Westinghouse is an Excellent choice.👍🏾

[@rickbraden4272]

The voltage was down over 10% & as low as 104 volts I think. I wouldn't call it a winner. I'd rather the breaker trip before it got that low.

[@GeneratorReviews]

True! I would have to agree with you 👍🏾

[@Moneyhan1]

Love your video. Curious, what elevation were you at when running these tests? Looking at these but trying to see if they will be enough when elevation is at about 6,500 feet. For a 5th wheel with 2 AVs and typical electric goodies.

[@Moneyhan1]

2 ACs

[@GeneratorReviews]

I’m in Texas so not much elevation almost at sea level

[@bruceyantis]

Thanks Gavin

[@mannyfragoza9652]

Garvin have you seen these yet maybe you can be the first to review one ALP GENERATOR 1000 W - ORANGE / GRAY Propane Generator

[@GeneratorReviews]

Wow that’s the propane only generator in a 1000w nice 👍🏾

[@stephencarlisle6339]

That is amazing. Onan must use better electronics. Gavin thank you!! Great video. 👍

[@machaf]

My thoughts: Cummins ran all that equipment because it dropped the voltage to 105v. That low of voltage is not really good for sensitive electronics. Westinghouse seems better to me as it overloaded before allowing the voltage to drop too low.

[@GeneratorReviews]

Yes it shut off at 40amps after I added some more load.

[@mb_a5383]

Thank you for that

[@Satalink]

Westinghouse overload protection kicked in whereas the onan didn't. I'm my view, the failure of overload protection to react to your abusive load make onan defective by design. I would expect the onan is going to need service repairs more frequently comparing the two models.

[@leerodriguez902]

This is a great comparison thanks

[@generatorbible]

Great vid Gavin!

[@kimsomerville1781]

It’s only a 30 amp outlet. So in my opinion the Cummins failed.the outlet and the cord adapters only rated for 30 amps and running almost 40amps make me feel like the circuit wasn’t protected properly.

[@GeneratorReviews]

4500w divided by 120v is 37.5 amps that max output of a 4500 Generator +/-

[@kimsomerville1781]

@@GeneratorReviews I have the Westinghouse I4500 and I know and understand the equation you spelled out for me, but it’s a 4500watt surge. 3700 maximum constant operating wattage. Now go add up all of the amperage of everything you were running in your RV.. the RV plug you plugged into is a 30 amp plug. I’m not trying to argue with you but in my opinion the Onan should have tripped. After 40 plus years of being a firefighter and still active, when I see things like this all I think about is over heating a circuit snd a fire breaking out. You said on the video that the overload light was on and it didn’t trip. That’s a failure in my book

[@GeneratorReviews]

@@kimsomerville1781 If I was testing the trip limit yes I’m testing power output. I’ll make a video and overload it to see where trips We’re not arguing we’re just having a discussion trying to figure out what happened it’s OK I love this stuff.

[@Flyingfinn82]

Great video. Would you be able to do a review on the Generac IQ3500? Looks like an amazing generator but hard to get

[@utubetjc]

Also interested in his comprehensive analysis. I bought one last month and very pleased so far. My genny collection includes: Honda EU2000i, Generac iQ2000, iQ3500, Westinghouse WPro 8500 and iGen 2500.

[@JB-cw5uu]

Hello I was hoping to get some advice from you I need a generator to replace my Onan microqiet 4k I’m considering these 3 options Champion 4650 with remote start gasoline inverter Genmax 4800 efi remote start gas with the extended run cap tapped into my coach fuel system And the Westinghouse i5000 inverter gas remote start I run one ac unit a microwave lights and coffee maker Do you think any of these would be best suited , my plan is to plumb the exhaust out the Rv like the onan and put a fan in the compartment for cooling and leave it installed on the tray that’s they I was thinking the Genmax would work best with that cap but honestly I’m not sure if it would overwork it

[@GeneratorReviews]

Why don’t you call me? We can chat about this. www.gavins-garage.com/

[@christinescheiner5194]

So thorough!!!

[@GeneratorReviews]

Thanks 🙏🏾

[@oks3ranch]

I wouldn't say the Onan is the winner based on it not shutting down due to an overload condition. The voltage was dipping all the way down to 103 volts while in the overload condition. Allowing your equipment to continue to run in this "brown out" condition could be harmful to the equipment or generator itself. It's my understand that Westinghouse manufactures the Onan Generator. That's what I've read on the interweb anyway. I bought the Westinghouse igen 4500DF model. It runs good at low altitude but runs way to rich at higher altitudes above 5k feet on gas. It for sure needs jetted if you are going to the mountains, fouled the plug and left me without power last trip.

[@GeneratorReviews]

Thanks for watching The Westinghouse 4500w is an awesome generator and yessir you are right about allowing your equipment to run in low voltage can and will damage your equipment or generator I really appreciate you living this comment it helps educate our community. keep that Westinghouse maintained and you’ll get years of service. Thanks James👍🏾

[@randybobandy9828]

Thats exactly what I thought. I wouldn't want to run more power on my generators if it means running @ 103v. That's a dangerously low voltage that can damage your electronics or appliances.

[@randybobandy9828]

Does that 4500df come with a remote start?

[@oks3ranch]

@@randybobandy9828 Yes it does.

[@MrJohnnybmoore]

I find it problematic that the onan didn't kick off at 30amps. I championed the Westinghouse because it did what it was supposed to do. #30amp

[@GeneratorReviews]

True!!!👍🏾

[@ophirpass]

I can’t find the Onan in dual fuel but Westinghouse offers it.

[@GeneratorReviews]

Onan doesn’t have a dual fuel model

[@utubetjc]

Well done....great review!

[@GeneratorReviews]

Thanks TC

[@stephenwhite5444]

Great video! When you turn these on with the remote start to they start in eco mode? I've read reviews of them starting in eco then not automatically kicking over to normal power when it sees load. Has that been your experience when using remote start and eco mode?

[@GeneratorReviews]

So both generators have Manuel Eco switches so if you leave Eco switch on it’s gonna start in that mode The champion 4500 has automatic Eco mode so it always goes to eco-mode when remote start But the Westinghouse and the Cummins you can actually pick which one you want it started in

[@fisheye42]

I appreciate the O-scope test of their sine wave output. For reference: At 13:03 for the Westinghouse igen4500, and at 13:25 for the Onan Cummins P4500I. They both claim

[@GeneratorReviews]

I don’t think the one I use has this feature

[@rooseveltrainesjr7618]

Thanks for the video I have a 18 wheeler an I'm looking for a remote start 4500

[@djwilson48625]

Champion 4650watt is a great unit.

[@chicagochris1988]

I’d buy another Westinghouse any day over that copy. I’ve had one for a year not this model but the 3600 open frame, I’ve started it on the first pull every time even in -20f weather to keep my electric heaters running with the furnace on in the winter, never had an issue, honestly for testing wise those are not designed to run a dual ac coach. I’ve never blown a circuit on my with 3600 running watts in my 28 foot travel trailer. Run the air and microwave all at the same time. Plus it’s more efficient if you stay in a camper to always have the refrigerator run on propane. A 30 pound tank takes care of my fridge and cooking for nearly a month. Good review tho I enjoyed it

[@GeneratorReviews]

Thanks for watching 🙏🏾

[@GeneratorReviews]

These are the kind of comments I really enjoy reading, offer something to the community. humble and polite Thanks 🙏🏾

[@brianallen0826]

I have a 28ft travel trailer with a 15k ac unit, I need to get an inverter generator, as I have a 10500,7500 troybilt but it's too loud and too heavy to use as a power source for camping. I am thinking of getting a softstart installed, but one of these gens may work well

[@scottmacglashin3059]

Great comparison, but my question is, if it hits overload, wouldn't you want it to shut down? Doesn't that protect the unit, along with what you're powering?

[@wyliesdiesels4169]

no you dont want or need it to shutdown as in the engine shutting off. you want the breaker to trip, which is exactly what the breaker is designed to do on overload. also the breaker tripping is for protecting the generator head NOT the load

[@fixtradingconsulting2935]

@@wyliesdiesels4169 that unit is rated at 37amps. why didnt it either shut off or breaker pop when the onan went above 38? am i wrong or did that onan overshoot by alot, is that a hazard? maybe im mistaken.

[@mattday870]

Thank you for this video!

[@joshuadereu7967]

DO you have soft starts installed in your ac units

Excellent test. Thanks

[@bcobrag]

Looks like I’ll be buying the Onan

[@Rick-be6fd]

I agree with Randy Hunt. That is not necessarily a win for Cummins. From this test I would buy the Westinghouse.

[@GeneratorReviews]

Yes I agree also the Westinghouse held the voltage in the safe zone and protected the load by tripping the breaker. Thanks for watching Rick
