    Ladderal wire from utility company
    Hi, I'm installing a 400 amp service with a 320 amp continuous let through meter socket. The utility company ran 350 aluminum from the pole to a pedistal in my yard and told me I had to supply the lateral wire from the pedstal to my meter socket. So can I supply parallel 4/0 aluminum SER to the meter socket? I think that equalls 370 amps under the 75% collumn. Thanks for your help

    I typically run 500mcm AL to the line side of a 400A residential meter socket, then parallel 4/0AL to two 200A panels.
