I have wired up a Jacuzzzi that it turns out is set to draw 36amps. I used 8ga NM for part of the run, which for no reason that I can comprehend, is rated at 40 amp. I propose to use a 40amp breaker to protect the circuit.
I am not troubled by running the wire steadily at 36amp, I really think that it can take a fair bit more than this.
But how will the breaker perform? I know that one traditionally runs a circuit at 80% of the rating of the breaker, and can make out with ease that 36 is 90% of 40.
What do you think? I don't want to reconfigure the Jacuzzi (apparently it can be set to run under a 30 amp breaker but this precludes the heater running at the same time as the two pumps are running at full speed.)
