I'm 90% sure there is a 100amp breaker running to my shed subpanel but it was a homeowner job so I want to verify everything is correct.
The subpanel has no main breaker though but I can see these three wires running to the shed from the main house. There are no markings besides the white stripe on one and they are 0.4" thick, what AWG would this be?
I'm assuming two hots and a neutral, no ground? Any guesses as to what this wire is and if it is in fact made for a 100 amp breaker?
Edit: I guess another question is, do I need a ground as there isn't one.
