[RE-wrenches] Bus bar battery jumpers

[Glenn Burt]

Drake,

I found the information available online at the Copper Development Association website to be valuable for DC applications:

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 the anticipated current, copper bar stock from McMaster Carr and cut, drilled and applied heat shrink myself…

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
