    Hello,

    My battery bank required 0/4 size of cable, but I don't have that big cables, but I do have 0/1 size. So instead of 0/4 size wire, can I use double 0/1 size to connect to battery bank?

    Thanks for help

    Yes, two awg 0 should have the same cross section as one awg 0000.

    There are certain standards that might not allow paralleling of cables or require certain requirements that must be met.

    Being cheap is never a good thing when running power cables....

    During loading about 350Adc to battery bank, is the double 0/1 awg cable able to handle the load?

    Thanks

    According to the national electrical code
    0 AWG (commonly referred to as 1/0) will carry 150 Amps if enclosed/buried,etc... (w/75deg C terminations)
    or 230 Amps in free air (w/75 deg C terminations)

    If this application is in the US you better follow the NEC and the installation manual for any products you are using.. If not you could be held liable in the event of a fire,etc...

    Doesn't the required voltage drop/cable length/resistance have something to do with this?

    Yes. The resistance of the cables determines the heating that will happen. The insulation is carefully measured and rated so it will not degrade when used according to the tables that wookie referenced.

    If you do use two or more cables be sure to fuse each separately for fire protection if one cable opens.

    The degradation of the insulation depends upon the type of insulation. That's not charted here.
