Is is necessary to use BOTH inputs, or will it function just fine using only 1?

Also, is 0g the recommended size to split to four 8g, or would 4g work jsut as well as the main power supply to the block?

Thanks
Dusty,

Please see the table in the link below. To answer to your question as to what gauge cable you should use for your input when using (4) 8 AWG outputs - you want the size of the input (cross-sectional area) to be equal to or greater than the cross sectional area of the (4) output cables added together. So according to the table, (1) 2 AWG cable has a cross sectional area that exceeds the cross sectional area of (4) 8 AWG cables so (1) 2 AWG cable is fine for your input assuming you have a relatively short run from the battery to the distribution block.

Hope that helps.
