Underground cable conduit and length
We're doing a new home construction and there is a 300' distance from the att service at the corner of the street (same as corner of the property) to our house (it's a large property).
We're having trenching done for various other services, so we want to lay a conduit for att right now as well.
Would a 1" conduit work?
Can it share a trench with other services such as water/gas/electric?
Should we call an att tech out to the site for a consultation or just lay the conduit down?
any input is greatly appreciated, thanks.
