What is the minimum diameter grey pvc pipe for the following direct burial cable?
Aluminum 4/0 2/0 4/0 urd?
Aluminum 1/0 2/0 1/0 urd?

Can I run a #4 copper ground wire in the conduit with the urd cables

Thanks

Thanks for the response,
I did type the second wire wrong, it is 1/0 2 1/0, will this handle a 100 amp panel

Yes it will.
