There was a HVAC guy killed in our neighbor town about ten years ago because of this exact same thing. I used to think about the unit being "live" but I've gotten casual lately. This is a wake up reminder..

@davidca96 5 месяцев назад

I do work on CATV transmission lines, one time working on underground lines we had dug a hole and kept getting shocked by the dirt itself in the hole, enough to hurt like here but not enough to harm us thankfully. Turned out to be a street lamp nearby its wiring was energizing the ground itself, never expected it or ever ran into it again so far. You do this stuff long enough you run into all kinds of oddball situations, glad you werent hurt Curtis.

@mxslick50 5 месяцев назад

That loose insulation looked like it was touching one of the hi limit cutouts. That was what most likely caused your shock. It would have also given you that resistance reading you got when testing the load side on the contactor. EDIT: Nevermind, commented before you found it on the dead motor.

@jimdarhower4945 5 месяцев назад

How did he get shocked though? How did he complete the circuit so to speak.

@mxslick50 5 месяцев назад

@@jimdarhower4945 (Bear with the length of this answer, but it is a complex thing to fully explain.) The grounding of the unit might have been a bit weak, but the main reason is that electricity will take ALL available paths back to it's *source* (one path of which is through ground and/or neutral, and since Neutral is not present here, ground is the only other path.) How much of the current takes each path depends on the electrical resistance, and in this case Curtis, in contact with damp soil, made a path good enough to flow some of that current. There are videos on this topic that you can search for to get a more complete explanation.

@user-ns3fl1tu4q 5 месяцев назад

There is most definitely an open somewhere in the grounding circuit of that system. What you experienced could have been a lot worse if your body would have been grounded more than it was. You might consider checking that out further or recommend an electrician get involved if you would rather not mess with it. PHEW!!

@johnathandye5244 4 месяца назад

This does not happen often, usually the breaker will trip when you have a bad motor, that was a good explanation of the electrical issue though in the other comment. However I just wanted to say you offer quality service and care about fixing things the right way. Nice to see, this is coming from someone in the feild for 20+ years and I work on anything from 1 ton mini split to 1500 ton centrifugal chillers. Job well done my man.

I recoiled instinctively when you got zapped, even though I knew it was coming! So glad you weren't hit harder! Had a kitchen exhaust fan almost get me like that. Just got a tingle, and thought to check with my meter. Found entire fan chassis energized at 120V because a wire had chafed through. Some genius had stopped the breaker tripping by unhooking the ground wire at the panel! Bonus points for no disconnect on the roof and each leg coming from a breaker in a different panel.

@jthonn 5 месяцев назад

Exactly@@Bob.W.

@jimharmon3404 5 месяцев назад

Well Curtis the frame and cabinet is not a ground in and of itself. It has to be grounded by way of the AC supply. There must be a ground bond at the Main circuit breaker panel only. For you to get shocked there has to be two faults, one looks like it is the insulation blanket falling onto an exposed heater connection making the cabinet hot. The second fault is in the ground system where the ground conductor is open between the Air Conditioner and the Main Circuit panel in the house. That too must connect to earth ground on the utility pole which may be faulty creating a shock hazard for the entire house. You should report that to the utility to have them check that out ASAP.

@gor312 5 месяцев назад

Not the utility pole. The ground connection is normally done where the service enters the house, either with a grounding rod or a Ufer ground (rebar in concrete). Either this connection has failed (very dangerous but unlikely), or, more likely, the unit itself was never connected to safety ground by the installer.

@boomer9900 5 месяцев назад

There is a break in the grounding somewhere in the unit, house, pole. The owner should call an electrician and have it checked out because if it the ground then other appliances could be energized too.

@vickslab4608 5 месяцев назад

That's one way of waking up in the morning.

@brushben22 5 месяцев назад

My bet. The insulation foil was resting on the motor breath/vent plate and caused your windings to thin the insulation. Very important for motors to breath and I’m surprised it lasted that long

@w.knudsen5570 5 месяцев назад

With that chassis being hot like that, I would be concerned about a high resistant connection on the bonding.

@dashcamandy2242 5 месяцев назад

Thank goodness you weren't standing on wet grass, or in a small puddle, or this video could have had a completely different ending!

Every time it rained or it was foggy and I touched this one particular box, I'd get a definite tingle! The box was secured to a metal lamp post by a metal chain, so... Yeah. Fun times.

@wmcomprev 5 месяцев назад

@kg4muc 5 месяцев назад

@stangaloski4208 5 месяцев назад

Ya i had a hot unit once. Finally found a lighting circuit was rubbed through on the metal ductwork. No idea why it didn't trip but it was about 90 volts as well.

@mxslick50 5 месяцев назад

Too high of resistance through that duct path for enough current to flow, which means the breaker didn't see it as a fault, but as a small portion of the load. Same principles applied here with this AC unit.

@Aerospace_EdC 5 месяцев назад

Curtis, that should not have happened if the chassis bonding to the supply ground was intact but I guess over the years the metals got corroded and lost a good bonding ?

@jthonn 5 месяцев назад

Voltage to ground, I always worry about that on older homes. I have seen many times where the ground wires for a light fixture or whatever will be hooked to the common. I have even seen it on 220 appliances. So we have a 20 year old unit with all new parts. I guess if you think about it, the rest is just sheet metal. The furnaces worry me though, like the last one being so rusty. Anyhow, nice work. Also, I don't think .3 amps on a motor like that would make any difference, especially being lower.

@Bryan-Hensley 5 месяцев назад

I used to work for a satellite company and was sent to Lowe's to diagnose hum bars in the monitors. I disconnected the coax going outside to the satellite dish and it knocked me off a ladder. Long story short, the building was energized. I think it was something like 70 volts. Their maintenance didn't believe me so I ended up calling the light and power inspector. They found a main ground connector had high resistance somewhere. However the building was being energized by some bad lighting ballasts.

@mxslick50 5 месяцев назад

Yes...and no. As I explained in another comment, since electricity will take all paths, it will divide amongst them, and Curtis just happened to be a part of it. But in this case the unit (or the house in general) most likely has grounding issues. A proper low resistance grounding path would make that current that Curtis experienced so small that it would not have been felt. (Or in the ideal world, totally eliminate it.)

I had a similar problem a few years ago. I lost power to my garage and I was using a "Tic Tac Tracer" lookin' for power. Nothing.

@francisbriggs76 5 месяцев назад

@garypoplin4599 4 месяца назад

4:18 - _There’s_ your high voltage to ground! The foil backed insulation is touching one of the heat strip overloads. Put the insulation back into place and _Viola!_ No more short. Since it was not a solid contact, the breaker doesn’t trip; nor, does the point of contact burn. EDIT: After watching the rest of your video, I see you concluded the motor was causing the short (8:36); but, notice here also the foil side of the insulation was no longer in contact with the terminal below. The motor _did_ need to be replaced because of the sloppy shaft; but, I suspect if you check the motor windings, they will ring true and will not be shorted to ground! If you still have that motor, check it. You may find that the short was cleared as soon as you moved the insulation off the heat strip terminal and not from pulling the leads from the blower motor.

@jamesoestrike2517 5 месяцев назад

Likely the replacement motor was more efficient, so therefore less amp draw.

@ntsecrets 5 месяцев назад

It seems the unit isn’t properly bonded/ground. Next time you’re there, with the disconnect off, measure voltage from L1 at the disconnect to the chassis of the unit, you should read full L1 voltage if the unit is properly grounded back to panel/ ground. If you dont read full voltage you may have a grounding problem.
