THE WALK IN FREEZER BREAKER IS TRIPPED

[@bigclivedotcom]

I take a few pictures from different angles when disconnecting stuff for replacement. Takes seconds, but can save a lot of time. Sometimes I also go back and look at past videos on my channel to see how things are wired or assembled. It's a good visual archive.

[@Phred_Phlintstoner]

I agree completely! Makes life so much easier!

[@mwiz100]

Yep, I've learnt this the hard way in going back to look at the ONE photo I took and it doesn't have the angle I need to see the connection I'm trying to figure out. Always take a few now.

[@sonictraxx]

Love you Big Clive!! Been a long time supporter of your channel along with HVACR!!

[@bigclivedotcom]

@@mwiz100 Yeah, a few angles are important to avoid those hidden wires.

[@Bryan-Hensley]

I take pictures of anything I'm fixing to unwire.

[@ryansmith2567]

Forgive me for sounding like a know it all but this isn’t my intention. You say you have 30A fuse installed then a 40A breaker upstream from this. The issue is that circuit breakers have different tripping characteristics to fuses. Fuses will actually withstand high overload current draw for longer than a breaker. So normally if you are going to protect a fused circuit with a breaker you have to oversize the breaker in order to provide discrimination between the two protective devices. For context I am an electrical engineer on the railway who works on three phase installations in the UK. For example when we have a 63A fuse installed we have to use breakers sized 125A upwards depending on the cable length between the two. Again not being clever just wanted to provide an insight to the fuses and breaker. Great videos by the way!

[@akareject]

This video is another example of why I enjoy watching this channel so much: troubleshooting. Every video is a textbook of information in how to troubleshoot. This time it was troubleshooting a client equipment issue AND an operator issue. It takes a professional to know to throw power off immediately when the compressor sounded bad, take a step back, find the issue and correct it even if that meant admitting operator error. Thanks for including the mistake, working through it, and showing it wasn't the end of the world.

[@TheLenaweeTrekker]

Mistakes happen, but the real test of a technician is owning up to his mistakes and correcting them. Yeah, it's hard working with your tail between your legs, but it's in the job description. My photographic memory helper did the same thing, and I immediately knew what was wrong. I kept him on the hook for 20 minutes until I said rotation. He got it right away and corrected the wiring. I told my helper that I have done it too. It seemed to help. I don't think there is a technician worth his salt that hasn't made simple mistakes.

im a mcdonalds overnight manager, and my only experience with hvac is replacing the condenser fan motor at my home because im too cheap to pay someone to do it for me. i love these videos and use them to fall asleep to often, keep it up providing me sleep audio

[@MichaelG63]

When I used to fix light boards and soundboards, I would take pictures of everything before I removed anything. As someone in another comment said, they went back and looked back earlier in your video, as did I. Even before that, I was confused as to why there were red and blue wires going into the center of the top of the contactor. As you said, you found the problem and fixed it. That is the important thing. Imagine trying to connect a megawatt generator to the Grid out of phase. Because the Grid won't move, most times the generator tears out of it moorings and flips itself to fix the phasing.

[@Davemte34108]

Oh, so many times... Worst one was on a 5-stand rolling mill with a down time cost of $5,000 a minute that I kept down for almost an hour, until I found the issue that I caused. I was was forgiven because I had saved them so much downtime previously, always be honest.

It’s amazing these people spend money. I’m a commercial air con tech in Australia and it’s an absolute song and dance show, just to receive approval to supply and fit replacement filters.

[@ehsnils]

I have seen a case where a bug got trapped between the half-cores in a contactor once. It prevented it from pulling together fully. Another thing to check is that the coil voltage to the contactor is correct.

[@afortyoz2freedom]

I am a transit bus driver, nothing I do is connected in any way with HVACR, but your videos are so fascinating. I only understand about half of what you're talking about most of the time, but it doesn't matter.

[@guygfm4243]

It was black blue red on the end thanks for sharing love the videos

[@concealed4carry]

As an electrician I work on contractors often. As one person mentioned chatter causes arcing, arcing causes heat, heat causes carbon buildup.So what causes chatter as someone else said low coil voltage, or more likely a week coil caused by dirt in the plunger or coil windings comprised and shorting. You should take a resistance reading across the coil terminals and test to ground.

[@brad346326]

Great video it takes a big person to admit a mistake and a bigger person to admit it on video much respect

[@Iippo82]

It's nice to see how totally different everything is on electric side of those machines compared what i see here in Finland, i mostly work with grocery-shop refrigeration systems. On those wire colors. it's really strange that blue is live-wire, here blue is color for neutral :D, usually when changing electric components i take before photo to get things right.

[@BenjaminEsposti]

In the US, 120V and 208V/240V are black-red-blue (white neutral), while 277V/480V are brown-orange-yellow (gray neutral). We've also got funky utility transformer setups on some occasions: corner-grounded delta, high leg delta (for split-phase AND 3-phase loads), and open delta ("fake" 3-phase using only two transformers - it's real 3-phase, but the 3-phase load capacity is reduced compared to having three single-phase transformers, and the 3ph load is required to be balanced). On rare occasions I've seen the utilities use three-phase transformers to supply customers - some are rectangular like the ones you use in Europe. But otherwise, they tend to use three single-phase transformers. The single-phase transformers can be used in a variety of different ways (but is 15% more costly than a single 3ph transformer). (Exceptions are for large loads, like a mall or industry. There they'd use a pad-mount transformer or a switchyard.)

[@ke6gwf]

Back when I was a mechanic working on wierd old military surplus vehicles and old industrial machinery, I got in the habit of taking a picture of things as I was taking it apart, wiring, which way a spring hooked on, etc.

[@kennyash1]

HVACR I'd just like to say a big thanks. I live in the UK and didn't have a clue about air conditioning to be honest. I bought a few books and with your online videos I applied some basic knowledge and managed to install my own mini split heat pump on my house which has saved me hundreds and it works flawlessly! I know you mentioned that you don't intend on people that know nothing to start on HVAC from your videos but it gave me confidence and key info thanks again. Ashley

[@Pyro4100]

When you got to that point where you were questioning the wiring after you heard it rotate backwards I went back in the video real quick and figure it out real fast that you switch the red and the blue wires it happens it's fun times in my shop we have 480 3 phase I have purchased a rotation tester for that very purpose LOL any good video thank you for posting

[@jphvac5725]

Had that same exact looking model for WIF that had a bad low pressure switch, took me forever to finally catch it acting up. It caused contactor to chatter when it acted up. Good job finding the problem!

[@arturf209]

That's exactly why I always take a pictures before disconnecting something, if it's many then I take few pictures from different angles ;)

[@jefferygrady3181]

Good find on your mistake alot of people probably have made or will in the future make that mistake and can learn from your mistake! Mistakes are part of learning they are not bad things after all!

[@eglandon16]

Having watched your other videos and hearing the sound in your intro clip I kinda knew what to pay attention to do it was easy to spot, but then it's easy when I'm sitting at home watching a video it's a lot different when you are there and in the moment. I've made mistakes like this and it really leaves you checking your work multiple times to make sure you did everything right especially after burning something up.

[@fredflintstone8048]

It's easy to get phase rotation wrong when reconnecting to replacement parts. The key is to check and fix it. It's not uncommon for a breaker to trip instead of a fuse blowing, even when the breaker size (amperage) is much larger than the fuse. This is often due to a much higher AIC rating on the breaker than the fuse, so the breaker responds the the high current (short) much faster than the fuse.

[@instrumenttech4220]

I tend to take a picture before I change parts now old and dyslexic lol 😂

[@paulsawake3369]

I usually snap a couple of pics when swapping out a relay or breaker like that. Been there, done that before loosing where wires go.

[@Superdugge]

it was black,blue,red.. you wrote it wrong. and reversed the wires. you can even see the bottom wire numbers

[@liviu2004]

Circuit breakers can be decalibrated on thermal overload trip part. A 30(?)A fuse trip curve might be above circuit breaker trip curve in overload and scc area. Selectivity is not usually achieved with one step downsize but usually with 2.

[@RayRay-nb7tn]

[@TehGordonFreeman]

Amazing video, as always. Quick question, do you have any suggestions for an evaporator cleaning compound that's safe to use on supermarket produce display cabinets and walk-ins? I can't use anything scented or that has a strong odour (like bleach) since the customers complain that the produce smells like bleach/lemon after even gentle use with lots of rinsing. I'm sure you've done your fair share of supermarket work, but let me tell you, if the customers saw what the evaporators look like that sit six inches under their food, no one would ever forget to wash their produce before they eat it. Thanks in advance :D

[@hvachacker586]

Always pull the panel cover or hit it with a thermal cam. Loose breaker lug will heat up and trip the breaker and cause a recall. Another thing on them heat craft units is them anti shortcycle timers are terrible. I had one fail on commission they will tear up a contactor with chattering it. I recommend replacing the contactor with the copeland contactors. Much heavier contacts and remove the timer. Let it cycle a few time in defrost as residual refrigerant boils off. Helps with diagnostic of a bad solenoid or leak back on a compressor reed.

[@mnshp7548]

there may of been a brief power outage, backpressure could of stalled or ran the compressor backwards in a split second when there was no power, then when power was restored it tried to force the compressor to run while it is still under pressure, popping breaker.

[@TheBrummybear]

In commercial washing machines particularly the older ones contactors are used with a relay to change the direction of the motor. My most spectacular mistake was connecting the spin and tumble contactor wrong and when i switched it on and set it off it was fun to say the least as the washer with 50KG of washing spinning full of water. That tripped the braker and flooded the joint.

[@KD0LRG]

Oh shit the spinning tornado of water. Guessing the seals just didn't hold? I had a claim with someone that had a full load of hot hot water pour out on their feet and sent them to the burn unit. They somehow opened the door, no idea how they did that.

[@TheBrummybear]

@@KD0LRG In commercial machines if there is a fault the door unlocks but remains closed. In domestic machines the door has a heat sensor and the door will not open if the water is above 40c. And the flood i described above came out of the steam vent. Doors do open occasionaly with hot water but this is usualy becuse the lock its self is faulty.

[@captainkirk7702]

I’ve wired a blower motor on a Starbucks store wrong and it blew up! The manager came to the roof in a matter of seconds to see what was going on and this is what he got!🤪

[@stormeagle28]

My bet on this one is on the contactor. I've had the same issue with an old-aged contactor on a high pressure cooling water pump for a milling tool. Here in germany such things are powered by 400V 3-phase. On disconnect the electricity inside the contactor found a way from one phase to another and an arc ignited, causing a phase-to-phase short tripping the breaker. There was a big-bang-party inside this contactor, but no visible damage. If you measure it out everything looks fine. If you reset the breaker everything runs fine. Until someday, maybe tomorrow, maybe in a month, maybe never such an arc ignites again. I only was lucky that I've seen the bright flash inside the contactor which made me think hey... could be a good idea to replace that one.

sealing the inside of the electrical pipe will stop that problem of ice inside your connection box. moist air will travel down the pipe and condense and in a freezer make ice.

If you cut the neutral but the circuit is live it tries to find ways to close the circuit so you might touch it and close the circuit on you.
