Yes.

Thought I would update this post. The garage was rewired correctly with 4 wire. The electricians who updated the main panel for the new gen rechecked their work. It took 2 calls to the local electric company but they finally came out and ran a load test from the pole to the house. The neutral on...

I thought I posted that I've run 3w w ground out to the garage with a new box and unbounded neutral. All is well on that front. 220 for the compressor and saw so load is more balanced. While connecting the new cable to the main, I noticed that the 220 line to the air conditioner compressor has...

OK. I think I get it. No current goes through the ground--neutral not needed for 240v motor. Thanks!!!!!

I've replaced the old 3 wire cable with 4 wire, installed a new sub panel, isolated the neutrals from the grounds and grounded the box and ground bar with 2- 8 foot ground rods. I figure that this may be a good time to run a 240v line to my compressor and table saw. I haven't checked wiring on...

I start digging next week. New 4 conductor cable. Thanks to everyone for their help!

No. It was a belt and suspenders type thing as I wanted to make sure the cable did not get damaged so I used an undewrground rated cable and conduit but some of the run is so convoluted I could not seal the conduit.. There are 80 years worth of roots and it was not a very straight run. I got...

NO. There is a 3 wire cable to the garage. What I propose to do is insulate the 3rd (bare) wire on the cable inside the main and attach it to the neutral in the main box. Then, insulate the 3rd wire (bare) in the garage box and separate it from where it currently resides on the bonded ground bus...

Yes 4 wires. While confirming that, I found a bare ground wire ground connected to the neutral bus and by way of exit attached to the box and then on to the copper ground pipe. There is a slight current flow there. The continuity test on the meter chatters and I find a few mlli amps on the...

They did put in a auto transfer switch for the Gen. The main service and the gen feeds it and then there is a 15 foot cable run to the main panel. On the first inspection, the transfer switch passed so I have to assume the bond between neutral and ground was OK. He then failed the main box and...

Thank you for the help!! Looks to me that I will be doing some digging and putting in 4 wire and probably a new box this week. I looked at the FAQ. One thing about the FAQ diagram post 2008. My electrical inspector insisted on adding an insulated bus for the neutral in the main box when they...

Many years ago I ran a 240V line to my detached garage using 10/2 UF w/ground copper inside plastic conduit. It is attached to the main box with a 30 amp 2 pole breaker. The outlet breakers in the garage box have ground fault breakers. The bare copper was used as both ground and neutral in the...
