It is 33 amps Total. Phase 1 current draw 33 amps, phase 2 current draw 33 amps, phase 3 current draw 33 amps = a Total of 33 amps MAX! Not 99 amps Total. Three phase 40 amp breaker or fuse for power distribution.
Thank you for the advice. I am using the flexible current probes. Really nice when you are measuring large diameter wires. Someone told me to measure both wires independently and add them up, but the distribution box that these are located in I couldnt get a mechanical clamp around but one wire...
800 amp 3 phase breaker, it has (2) 500 mcm wires connected to each lug, do i clamp around both wires or each individual wire for correct amperage reading. It makes sense to me even though there are two wires to each lug that both wires act as one wire is this correct.thanks
