Parallel SER Feeders

[multi5073]

Does the NEC allow or prohibit parallel feeders using type SER cable (in a building that is rated for its use) where the feeder is 1/0AWG or larger, the same length and installed side-by-side?

For example, is it permissible to install parallel 1/0 SER cables from a modular meter main (225A, 120/240V, 1?) to a 225A, 120/240V, 1?, MLO Load Center located in the same building (all concealed of course)?

It is allowed but you will have issues with the size of the bare EGC in the cables.

I agree, but will just add that cables can be ordered with proper EGC's for parallel operation. Probably not in stock at your supply house though :happyno:
