I am installing a 100 amp sub panel in a detached garage. My question is, can SER 1/0 Aluminium cable be buried underground in pvc conduit? Also is 1/0 1/0 1/0 2 aluminium cable good for a 100 amp sub panel?
If I'm not mistaken, aluminum SER is listed for above ground use only.
338.12(A)(2) prohibits the underground installation of SE or SER cable. With 75C terminals, #1 AWG aluminum would be the minimum required conductor size.
