Basic Wire AWG Theory and Current Rating
Basic Wire AWG Theory and Current Rating
(OP)
Hi, I'm looking at supplying 4.3A through a 19way connector, each crimp can accept max wire size of 22 AWG. I was looking at an AWG able to check the current ratings, for 22 AWG: in air 7A and in jacket 0.92A, so does that mean to get the 4.3A its 4.3/0.92 = 4.67, therefore I need 5 22 AWG wires to acceptably achieve the desired current. So with the ground or return I need a tool of 10 22 AWG wires to my connector to provide the 4.3A. Is there a table similar to translat the wire size into track dimesnions for a PCB for current ratings. Thanks Paul

The usual weak link is the contack resistance in the connectors, but you also have to consider the number of mating cycles expected.
