Hi: You could relate the cross sectional area of the copper bar to circular mils using,
1 circular mil = 0.166 sq-in Then look up the current carrying capacity for wires of various sizes in circular mils. A copper bar with the same size in circular mils will carry the same current as a wire of that size in circular mils; actually more current as the copper is not insulated and is not round.

Sent by: "RE-wrenches" <re-wrenches-boun...@lists.re-wrenches.org> Hi Wrenches, In building lithium battery systems, I have many components that need to be connected in series from the battery. Sometimes the space is very limited making it difficult to bend 2/0 cables. I would like to use copper flat bar and make parts to replace the cables. Does anyone know how much current I can run through copper bar based on its size? For example, 1" or 3/4" wide by .0625" up to .125" thick. The pieces will only be a few inches long and bolted to solenoids, shunt and terminal posts. -- Thank you, Larry Crutcher Starlight Solar Power Systems _______________________________________________ List sponsored by Redwood Alliance List Address: RE-wrenches@lists.re-wrenches.org Change listserver email address & settings: http://lists.re-wrenches.org/options.cgi/re-wrenches-re-wrenches.org List-Archive: http://www.mail-archive.com/re-wrenches@lists.re-wrenches.org/maillist.html List rules & etiquette: www.re-wrenches.org/etiquette.htm Check out or update participant bios: www.members.re-wrenches.org ______________________________________________________________________ This email has been scanned by the Symantec Email Security.cloud service. ______________________________________________________________________
