This is a great video. I had 2 new mini splits installed last year and the HVAC company put these in. Without fail, they did the job and saved both my units. They came back and replaced them for free! Since then I added a whole unit as well. For anyone watching this video, this is a must have.

[@bnasty267]

Great video. Like you mentioned at the end, I would start with a whole-house (SPD Type 2) surge protector at the main panel. It doesn't hurt to add additional SPDs at the AC disconnects or any other subpanels you have, but if you can only afford one, put it at the main panel. This is now part of the NEC (electric code). I would caution against installing multiple wires into the screw terminal like that, and it's generally not allowed. It's commonly done for these disconnects, but those terminals are only supposed to have one wire under them. It's possible that the screw won't make proper contact on the double stacked wires and it could arc and burn up the disconnect or worse. Either do a pigtail or I like the SquareD QO200TRCP disconnects with a switch that looks like a breaker (it's not actually an overcurrent protection device.) That allows 2 wires under the lug. That is rated for 60A, but it doesn't have to match the equipment, since the actual breaker is in the panel. The other nice thing about these is, you can replace the switch (with an actual breaker if you can't find the switch) if it ever burns out and not have to install a whole new disconnect box.

[@killer5846]

Great video! After watching one of your other videos sometime back, when I installed my three mini splits heat pumps in our home I also installed a surge protector on each unit. It gives me a little more peace of mind that if we do have a lightning strike or near lightning strike that the equipment should survive. As a matter of fact I was so impressed with how easy it was to install I'm going to have an electrician install a whole house search suppressor.

[@nrmerritt]

Nice video! We use a lot of ditek surge products for low voltage systems like cameras, alarms, networking and they have been reliable.

[@jstasiak2262]

I have two and possibly three issues with this video: 1. If you are going to go through the trouble of installing a surge protector on the AC unit, why not install a whole house surge protector on the main service panel instead? That way the whole house is surge protected. The installation procedure is similar except that you need to add a 30 amp double pole circuit breaker in the main panel. Whole house surge protectors are available on Amazon or at your local electrical supply store. Make sure to use one of sufficient capacity. 2. The National Electrical Code FORBIDS installing two wires on one binding post on the disconnect switch as was done in this video. This is a HARD FAIL. The proper procedure for connecting two wires to one binding post is to install a single pigtail on the binding post and then connect the two wires to the other end of the pigtail. 3. I infer that the AC condensing unit runs on 120 volts based upon the presence of a white (neutral) wire on both sides of the disconnect switch. However, most outdoor AC condensing units run on 240 volts, not 120 volts. If the AC unit does run on 240 volts, then the white wires are “hot” wires, not neutrals and must be labeled as such. If you are using Romex cable, you can do this by putting a band of red, blue, yellow, or black tape on the white wires to label them as “hot.” If you are using conduit, it is better to use a non-white, non green colored wire instead of a white wire.

[@atschirner]

It's 240 judging by the breaker opened to remove power from the disconnect. It needs a non-whiite or green conductor.

[@websurfer48]

Great info - thank you. Can this be installed on a roof mounted heat pump?

[@joeweatlu5169]

I am not sure why, but I attributed it to power surge. It happened twice. It always happened during thunderstorm. The blower motor was running on 230volt circuit. To remedy this, I ran the blower off of 110 volt and used surge protector. It has survived for the past three years after the change.

[@JC-gd3cc]

You are not supposed to combine wires under the lugs as it is a code violation and a potential fire hazzard. You need to pigtail them together below the lugs. Hope this helps and thanks for the video.

[@pete7894]

I agree we need a surge protector, the one used in this video has a lot of bad reviews and possible fake units out there. I installed a Pioneer Mini Split System so i stuck with a Pioneer surge protector for a few dollars more and installs exact same way. For example take note of the seller rating of the supplier in the link on this video. That seller has complaints of fake units.

Good info, I have a bunch of surge protectors installed, besides the obvious places like TV's and computers, on my main panel, at my heat pump outdoor unit, the AHU, at my washing machine.

That's exactly the way I hooked up an old Ditek to my generator's disconnect. I did this hoping if there was a surge from the generator my circuits would be protected.

With lightning storms, I turn off the systems and open the breakers. The power company has installed large surge protectors on their lines throughout our area.

[@cobbles62]

No. This does not protect a lightning strike close by. Power surges yes. Lightning strikes a bit further away - maybe. That is valuable already. However, I would go for a whole house surge protector, especially if your breaker box is full of modern expensive afci, gfci and dual breakers.

[@Imwright720]

Great for surges. Probably not effective on a close lightning strike, however. It’s still worthwhile.

[@timcat1004]

They won't trip from a surge and do nothing to protect from that or voltage sag. They are are quick acting triac that shorts to ground causing the circuit breaker at the distribution panel to trip.

[@redbaron6805]

[@redbaron6805]

@@chrish7927 It all depends on what path the lightning strike takes. I had a TV, cable box and an amplifier damaged during a lightning strike that was running on a UPS and a surge protector. The lightning traveled through the coax line, blew up the cable box, and the cable box blew up the HDMI ports through the video link and damaged the amplifier as it was connected to the TV. So, the power outlet isn't the only path for power surges to travel.

The Square D disconnect the other reviewer noted does not have a side knockout ( at least the one with same ID at the local HD). One would think they would revise these to accommodate the SP devices that now are more available ? I installed an Intermatic SP on my conventional AC unit at the no -fuse disconnect after we had a lightning surge destroy the AC contactor . I did “double lug “ the load (hot out) connections withe surge leads. The neutral had a second lug. The unit has been in service for eight (8) years now with no issues. Works great and I know of at least a couple close lightning strikes that could have caused damage but did not. I suppose you could pigtail the load and SP a shunt via a wire nut but that might (?) reduce the effectiveness of the shunt ? Anyway , still here, no spark outs , shorts, etc.

[@NycCitizen]

These devices have a Jules rating . The higher the number…the more energy they can absorb. The best location for the device is not next to the device you are protecting…but rather the beginning of the power line at the breaker box….this is becuase the line run provides electrical characteristics that results in the majority of the surge being absorbed by the device…if you put the device next to the item you want to protect…the surge goes to both devices. The electrical componet in that black box is probally the size of a dime and probally only offers 6000 Jules clamping and real protection does not occur until you get to 30,000 Jules and if the devices uses some type of inductive windings to shunt the surge away from the device…that would require the power runs from the unit needing protection to be moved to the black box in series with the inductors and have the clamping device on the other end of the inductor. This parallel clamping de ice will have a low protection ability.

Is it best practice to have multiple layers of surge protection or is one enough in most cases? Thank you, great video.

[@bnasty267]

You want as many layers as you can reasonably afford. One at the main panel, and one at any AC disconnect or other subpanels. You also want the standard surge power strips for any expensive stuff that plugs in. Modern electronics are very susceptible to power spikes (not necessarily lightning) and these SPDs are relatively cheap insurance.

[@redbaron6805]

It is cheap and easy to add a surge cube to all your appliances and electronics. They can be found for around $15 or so. I always look for the one's that are UL1449 rated, as they have a 330V voltage protection, vs the cheap one's can be 400V or higher. I have a surge cube on all my appliances including refrigerator, dishwasher and washer. Anything digital with a circuit board or a display should be protected. If you have a computer or expensive TV, use a UPS also.

IF you went to electronics school like me you would learn that surge protectors do NOT work against a lightning strike . The flash is so fast it laughs at the protectors as it passes through it. It does help with surge from the unit turning on.

[@redbaron6805]

Then you must have flunked electronics school. Surge protectors reaction time is measured in Nanoseconds, or 1/1000000 of a second. Lightning strikes can overwhelm and damage or destroy surge protectors if they are close enough, and no equipment will survive a direct strike. But claiming surge protectors don't work against lightning strikes nearby that cause power surges is 100% false.

If this is wired in parallel, how does it provide any protection al all? A surge protector needs to be in series before a device so it can be sacrificed to save the downstream device.

[@bnasty267]

The way these work is by using components called MOVs, which are basically voltage-based switches that only conduct current when the voltage goes above a set amount. The MOVs are connected between the hot leads and ground, and at normal voltage, they aren't passing any current. However, if the voltage spikes above the set amount (usually like 150V), the MOV 'turns on' and dumps that current to ground, often killing itself in the process. Usually, these voltage spikes are transient and fast, so the circuit breaker won't even trip and the MOV might not completely die.

[@diyhvacguy]

Wow excellent explanation sir. 🤘🏼

[@fritter6546]

@@bnasty267 I get it now - normal voltage always goes to the equipment and any excess is rerouted. Neat set up. Curious what happens on a large or extended surge after the MOV dies. If it is no longer able to actively dump the excess to the ground, won't all that voltage just be conducted to the end equipment at that point? Or is that a situation where you'll have bigger problems than your A/C unit getting fried?

[@bnasty267]

@@fritter6546 High end surge protectors often have multiple MOVs (sometimes half a dozen or more) wired in parallel to serve as backup and to handle larger surges. Similar to the unit shown here, usually there is a little thermal fuse essentially stuck on the MOV that turns off a little green LED when the MOV heated up from a big surge, and thus sacrificed itself. When the light goes out, that means it's time to replace the SPD, because it no longer offers any protection. You're right though, they can only do so much.

How do i find out which one will be sufficient for my ac unit?

[@Thomas-wn7cl]

Does this product protect against under voltage?

[@benkanobe7500]

And because it is AC (current) there is no "polarity" and that is why either one of the surge protector wires can go to either one of the load wires? (I'm sincerely asking).

[@diyhvacguy]

Correct

[@indexglow]

Great idea……i have a question though. I have 2 disconnects on my heat pump package unit. Which one would need the surge protector?

[@tangoseal1]

Both - the whole house is one big shared circuit and thus you need to protect the surge from coming Into tye AC on all legs that lightning etc.. can ingress.

[@diyhvacguy]

One is for your heat strip and the other is for your compressor and fans. The one for your compressor and fans is the one you want. It’s probably a smaller breaker then your heat strip 👍🏼

7:09 Amazon description says country of origin is china. Great idea. I need to find one not made by the ccp for my mini split.

[@redbaron6805]

Amazon description is obviously wrong, as the unit is clearly says it is Made in the USA.

[@davem3789]

@@redbaron6805 I got this from Ditek this morning - " the product is manufactured in Largo, FL USA using a mix of US and globally sourced components" I do give them credit for a quick and what appears to be an honest reply.

[@cheekybastard99]

Why china makes the best quality at this point.

Those lugs aren't rated for two conductors.

[@PeterPhan8888]

Can i apply this to my central air to protect my capacitor ? thanks,Peter

[@diyhvacguy]

It’s more for your circuit board, and other sensitive electronics. Not sure if it would help with a capacitor but it very well might!

[@PeterPhan8888]

@@diyhvacguy Thank you. Let me know when you are around Boston.

[@19BADGER-F250]

Would you install this the same way if my a/c is right next to my main and I don't have a a/c disconnect? Mine is set uo to just flip the breaker.

[@rhymereason3449]

How does something wired in parallel protect the equipment?

[@joeweatlu5169]

It absorbs the excess surge. I installed a similar unit, different brand, installs the same way.

[@ronaldnaeyaert3653]

I just installed a Siemens FSP140 Pro whole house surge suppressor in the main panel. My Carrier Infinity Series AC compressor is on a seperate meter and the wiring appears to be seperate from the main panel and is not most likely not protected by the FSP140. Can this device be installed and will it protect ths seperate circuit?

[@HoodHandyman]

what if your not using a disconnect and your using 120v with one breaker ? Then all you have is 1 ground 1 common and 1 load/line wire

[@tangoseal1]

It works with 120v as well and you can install it on your breaker circuit in your main panel that is for the AC

[@HoodHandyman]

@@tangoseal1 thanks

[@lambition]

Are you sure it is ok to have that surge protector outside? I don't think that is waterproof.

[@nomen_meus]

It is labelled as a NEMA 4X enclosure, so it is well protected against dirt and water ingress.

[@tigerz4487]

so this can be used as a lightning rod ,right、？

[@ldenorio]

so, should you buy 2, keep 1 as a back up?

[@diyhvacguy]

Not a bad idea
