I want to use a 50-pin cable to ignite e-matches connected to fireworks. The e-matches require about 1 Amp to ignite. The individual conducting wires in the cable are obviously very thin, and thus can't conduct a continuous 1 Amp current. My question though is this: can the very thin conducting wires safely carry 1 Amp of current if just for a fraction of a second? And how does one go about figuring out how much current is safe for short pulses through similar wires?
