Battery cable size

Is #2 AWG welding cable large enough for a T-bucket.

Should be, but it all depends on the electrical loads you have and how long the cable must be. When using the table below (2nd graphic), be sure to consider the total length including the ground side. See note at top.
.
Add up all your loads using the list below if you don't know how many amps your specific device requires, then go to the second graphic to see what gauge wire you need.

Thanks Indycars the charts help a lot. Looks like about 65 amps total with a length of wire at around 12 feet.
