I have a 100 amp panal @ house.
Want to run wire to sub panal in a construction trlr.
Trler has 60 amp main brkr.
I would like to run welder and compressor as wellas a few shop lites.
? is what size wire will be needed @ 200'
I will ground @ trlr (8' rod)
Can I use wire made for water well service?
Can I bury it in pvc?
Yes you will, but that is NOT your "ground". You still need to run four wires.
Sometimes I feel like if I answer any more questions it is like someone trying to climb over a fence to jump off a bridge and me giving them a boost.
