I've seen reviews where people said their breaker wasn't working when it was supposed to. Well, my situation might be related to that. I ordered a 15 amp switch but received a re-branded 20 amp switch. 15 amps at 120 volts = 1800 watts (my outlets are designed for this). 20 amps at 120 volts = 2400 watts and potential fire hazard. Be sure to check the parts you receive!
