After inspecting this home and finding virtually nothing substantial to report on because the home was virtually new and well constructed and maintained, I find myself second guessing this.
Aren’t the hot and neutral service conductor wires supposed to be of the same guage? Maybe I’m missing something when reading the NEC book. I’m used to seeing them all the same guage, so when I saw this I started second guessing.
I also have a difficult time judging service wire sizes. These were 1/2" and 3/8" dia aluminum conductors measured at the insulation. They seem undersized for a 200amp, but want to make certain before I call for an electrician. I usuall read the size on the insulation, but wasn’t marked on this one. Your guesses?
