I was testing how much amp my heater was taking up by testing the Amp but it tripped the outlet. I tried the test 2 times more and tripped every time. Why does the clamp amp meter trip the outlet?

  • Since you aren't using a clamp meter (pretty hard to trip the breaker with that), I assume you're using a normal two probe multimeter. Where are you putting the probes? What settings are you using on the meter? Nov 29, 2021 at 19:01

    Hmm. I thought "can't be clamp" because how in the world could that trip anything. But says "Clamp" in the title. Make/model # of meter? Make/model # of heater? Picture of how you are using the meter? Nov 29, 2021 at 19:07
  • I'm using a Commercial electric ms 2002 clamp meter. If this is weird, there must be a short somewhere. Nov 29, 2021 at 19:35

    This may sound stupid, but: This is a clamp meter that also has leads for other things. How are you using it to measure amps? Nov 29, 2021 at 19:37

    Thinking you are moving the wires to use the meter. Possible the wire insulation is damaged/ nicked somewhere, and your moving it to use the meter is causing a short.
