Moving overhead wires underground.
During a recent storm a tree branch struck a piece of overhead conduit between my workshop and garage (span of 10'). Since the conduit must be replaced, I would like to run the wiring underground. Is pvc the only choice? Running lights, door opoeners and outlets to a two-stall garage with a full sized lighted storage loft, what wire would be correct so I could replace the old and run one continuous piece.
