Made some bus bars for the new golf cart batteries, 1/4" x 1" copper. The terminals were so close together, I figured this was better than cables.  |

Why are the studs so short?

Why are the studs so short? With the 1/4" bar, that's all that was left. Just enough to get them to tighten down. Actually, I think those were not tight yet. They are flush with the top of the nut. Must have taken that while I was installing them all. |

You need to get the ut 100% on or the threads could fail. Especially with stainless as it's softer than other metals.

I calculated the load and 1/8" x 1" will carry 250 amps and 1/4" will carry 400 amps. The inverter can draw 100, so with other loads I wanted to make sure I wasn't under-sizing it. Not sure what the windlass draws but that is substantial plus other house loads on that bank. I know not everything will ever be running max at once but all of the other cables are 4/0 and I wanted to be consistent on sizing. |

I use 4/0 cable alot. I calculate it at a 425 amp capacity. Fuse it at 250 to 300 unless otherwise necessary.
Many of my systems use 2 or 3 banks each on a 4/0 cable and fused. Attached to a 1000 amp bus bar. Inverters all get their own line and fuse

I didnt think thered' be a 150 amp loss across a 1/8 vs 1/4" bar ! With 1000 amps you can weld some 2 inch thick fiberglass LOL...
