Hello,Does anyone know where I can find out how much current specific gaugesof wire can handle? I've looked up web pages on it, but can't figureout what they mean... for example atThere's a column that says: Current Carrying, and another that saysFusing CurrentI'm interested in figuring out if 20 AWG wire can handle steady DC of7.25 Amps, for 20 AWG is saysCurrent Carrying: 1.46Fusing Current: 58.4? I don't get what they're saying.... other websites have beensimilarly confusing..Much Thanks

then Jim's Engineering Page, then Wire Table.# 20 wire can carry any current you like, up to the fusing current. It is all a matter of how hot you are willing to let the wire get. The referenced table above will let you calculate the temperature rise of a wire over ambient for any arbitrary current and gauge.The Current Carrying is how much current the wire can handle for a given rise in temperature over ambient. There should also be a note that the temperature rise will be more than calculated if the wires are in a bundle together. An unbundled #20 wire at 7.5 amps will rise about 30F (15C) over ambient, which is pretty warm. Your call.Fusing current is the current at which the wire will melt.Jim

Said the retarded fuck that used to post under several nyms as well.

USENET is so simple, even a caveman can do it. ;-)
