12. 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! Service area Ottawa??

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

15. This is funny

16. 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. Are you in Nepean ?

18. 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.

22. 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

32. 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.

36. 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. Service area Barrhaven??

37. Just so you know I’ve wired up a bunch of scroll compressor is backwards and a sound like trains..
    resolve the problem by flipping the two wires around..
    Problem solved.
    Thank God it didn’t do internal damage to the scrolls

41. You changed your phase
    Old one
    L1 black
    L2 Blue
    L3 Red
    New one
    L1 black
    L2 Red
    L3 Blue
    Swotc back the red and blue… now where in my 30pk beer lol

42. I knew that sound immediately.

43. That noise from the compressor is typical for one that goes backwards so the first I would have tried would be to change the phase just to see.

44. Im not even near the experience that you have and i'm a big fan but i think you should considerer ohm it out to ground instead of tone to ground. If there is any resistance to ground something is up/grounded and if the multimeter shows OL you good 😉

45. 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.

49. 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.
