About 10 years ago I had a meter pole set with the intention of running 400' of underground copper cable to a new house that I am building myself. Of course within minutes of having the meter connected to the PCO the price of copper went sky high. Can anyone suggest alternatives for this run, is there any type of underground aluminum cable that might work? (400' with 4 conductors @ 200amp)
The vast majority of URD(underground residential distribution) is done with aluminum conductors.
Agreed. Same here.
400' is pretty far though for secondary voltage (120/240V). Did you clear this with your POCO or local inspector? You will almost certainly have to upsize the service lateral to 250MCM AL from the "standard" 4/0AL.
