Getting the shop going
i just moved. At the house is a double 40amp breaker with a service line that runs aprox. 150 ft. to a shop.
May the shop is a breaker panel (brand new) with 20 amp breaker (also new).
I measure the same voltage at both ends of the service line. Same at the single receptacle I have installed. However, when I plug in and turn on a load, the voltage drops to around 5 and the tool will not run.
What could be going on here?

It WAS a two wire plus ground 240 setup. I decided that the ground wire was most likely bad. I had replaced the exposed section already but I would not be surprised if more of it was trashed.
So, my solution was to use one of the original 6 gage wires as my common. So now it’s 120v on a single side of a dual 40amp breaker.

First some terminology:
Hot (ungrounded conductor) Which can be any color other than white(with or without a yellow stripe), gray, green (with or without stripes) or bare.
Neutral (grounded conductor) Which can be white with or without stripes, or gray.
Ground, which can be green, green with a yellow stripe or bare.
There is no common.
You may not use a ground wire as a neutral. You are removing all the safeguards from your wiring system.
