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.

@ryansmith2567 3 года назад

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!

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.

@akareject 3 года назад

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 3 года назад

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.

@MichaelG63 3 года назад

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.

@ehsnils 3 года назад

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.

@BenjaminEsposti 3 года назад

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.)

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.

@fredflintstone8048 3 года назад

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.

@liviu2004 3 года назад

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.

@hvachacker586 3 года назад

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.

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 3 года назад

@TheBrummybear 3 года назад

@@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.

@stormeagle28 3 года назад

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.
