A datasheet for a power connector I was looking at tonight has this warning:
Do not branch in parallel current which exceeds the rated current. If branched in parallel, current imbalance or other problems may develop. If it is absolutely necessary to branch such a large current in parallel, be sure to use contacts made of phosphor bronze. Design the circuits without causing imbalance and provide an extra margin for each circuit.
The connector has a current rating of 10A and has crimp pins that support 16AWG wire so presumably each pin of the connector can support 10A.
I read the language "do not branch in parallel current that exceeds the rated current" to mean that one should not draw more than 10A total across some number n of pins all hooked to the same power source.
I'm guessing it's a safety feature in case one wire of a parallel group were to break so that the remaining wires don't immediately have to take on a much higher current but I would like to check my understanding here.
Am I interpreting this correctly?
