Inspect my electric work

[Motown 454]

Hi I just wired my compressor and would like any electricians to check it and let me know if I should change anything? Its been a while sense I did any wiring so it will be appreciated.

Here is what I did


Should I put red tape or shrink wrap to make one red it changes to red from the disconnect to the compressor?



I made a loop in the green incase it needed to be moved to the other ground side.

This is the disconnect for the compressor, it came with another compressor I had. The ground at the bottom was there should I move it somewhere else or is it ok where it is and just tie the greens together with a lug ?



Here's the way the compressor is wired. There is no place for the ground should I put it to one of the bolts that hold the box to the compressor?




Thanks

I'm not a licensed electrician, but if you look to the right lower side of the contractor; last picture, you'll see a screw hole, it's for a ground connection. I'd buy a ground lug and ground there. Next question, where's the ground wire for the cable coming in on the bottom right? The top picture, I'm guessing where you have those washers, it might have been a hole there for a ground lug also, those washers need to come off and a lug installed. I was looking at the other pictures on Photobucket. Why didn't you run those 12 gauge Romex over instead of under the trusses? Are you closing in the area above?

For the disconnect switch, buy a 5 terminal ground bar kit, & install it per instructions, or HD should carry a lug that has 2 set screws, bolt that to the enclosure, a single lug bolted to the starter can will take care of the grounding issues there. Do not use sheet metal /TEK/ self-drilling screws to mount these items as it's not allowed by code.

See a example of a dual lug here:

Yep, it's got to be secured with the proper attachments. Good call Norcal. It looks like a three phase disconnect. The bottom is not properly marked. I didn't think you were suppose to remark conductors smaller than 6 gauge?

It seems a little odd that the compressor manufacture has not included a ground wire in the cord that supplies power to the motor. Also, there does not appear to be a ground wire in the cord that connects to the pressure switch either.

what is the black wire to the ground buss under the 100 amp breaker ?

That's the bonding bar from one neutral bar to the other side, the black is a covering like heat shrink over it.

Not 3Ø, it's a transfer switch, load at the center, line at the top, & inlet for gen at the bottom, the 6 AWG neutral conductor is white it is not remarked, inlet is a 60A 125/250V, 3- pole, 4-wire pin & sleeve device. Neutral is switched because it's bonded at the generator.

Thanks guys. I'll get the grounding lug done before I power the compressor. If you see anything else let me know.

is that 2p 100 amp the feed ?

they make a paste to coat the feed posts to prevent corrosion on the aluminum.

Here's how I did it. Does it look OK ?
