Do Amperage Ratings Add in Parallel or Series? Answered
I was wondering if the amperage ratings of devices, say, for instance, circuit breakers, add in parallel or series. For example, if I hooked up 5 20 Amp circuit breakers in parallel, would it take 100 amps to trigger them all? Or would it take 100 amps with them in series to trip them all? I'm not sure about this because I have used two 1 amp solid state relays in series to switch loads well above 1 amp, but it seems more logical for them to only do that if they were connected in parallel. Also, whatever the answer to my question is, does it apply to all devices? Circuit breakers, Triacs, etc? Thanks!
