What great information from you guys! Anyone who
saves these tables should be able to design bus bars with confidence.
Thank you,

Drake,
I found the information available online at the
Copper Development Association website to be valuable for DC applications:
<https://www.copper.org/applications/electrical/busbar/>https://www.copper.org/applications/electrical/busbar/
Hope this helps.

Glenn,
Thank you for that good information.
Where do you find the specifications relating
cross sectional area to amperage? Section 366.23
of the NEC allows 1000 A / sq. in. of cross
sectional area of the conductor. Is that a good
rule of thumb, or is there something more specific to battery busing?

I have always bought the appropriately sized for

McMaster Carr and cut, drilled and applied heat shrink myselfÂ…

Subject: [RE-wrenches] Bus bar battery jumpers
Hello Wrenches,
I am wiring a set of 2 V Concorde batteries for
48 V. Each battery has 2 terminals which will be
about 2 1/2 inches away from the terminals they
will be wired to. Standard battery jumpers would
be ridiculous in this situation. Busbars would
be clean and efficient. Concorde doesn't have a solution.
Does anyone know of a source for busbars?
Thank you,
Drake
