Underground cable v/s overhead cable from transformer to service entrance
Underground cable v/s overhead cable from transformer to service entrance
(OP)
Hello,
To feed 400A service from 50KVA transformer, is it a code requirement of any sort to have underground cable laid between the transformer and the main 400A disconnect or would over head cable also work?
What I wanted to inquire about is at what amperage/voltage it becomes a requirement or best practice to have underground cable v/s overhead cable between transformer and service entrance?
Thank you.
Tapan.

jghrist/cranky108: The installation is in Sydney Mines, Nova Scotia, Canada. So the Canadian Electrical Code would apply and because the CEC is more or less based on NEC, it may turn out that U/G cable may not be a requirement in Canada as well. However I'll verify if there is any provincial or municipal requirement.
My query is about if above a certain voltage/amperage would it be a good trade practice to have U/G cable rather than overhead cables?
Regards.
