I am wanting to get a subpannel into my new shop, but it seems that time is against me. I did manage to get 3 electricians in to give me a quote, but non of them want to give me a price. I didn't think it was a small job. I involves upgrading my house panel from 100amp to 200amp and putting the old electric box into the garage with a line run underground between the shop and the garage.
It's getting closer to winter and the ground is not getting any softer. I am thinking that I'd better get the trench dug myself if I want this done before winter time.
I know I need to go 18" down and can run a 1 1/2" pipe for 2/4g AL wire. Some have said on another forum that it's better to run 2" conduit.
That part I have no problem with. But then to meet the code you need to put something above the conduit to give warning about electrical wire. I am not sure what that is, or how to do it.
There is the rub. I can do the work myself but I don't know what is expected. HELP.
