    Well Pump Control Circuit Troubleshooting

    I have a 4-wire well pump (red, yellow, black, and green) which just quit. Cycling normally, then shut off and never came back on. I've gathered that yellow is the common, red is the leg for the start winding and black is the run winding. I've got a couple ohms (4-ish on my trusty Harbor...

    Australia Lighting circuit trips RCD but not MCB, can’t find E-N fault

    Long shot but thought I’d try, have a lighting circuit that trips the RCD as soon as the neutral touches the neutral bar for said RCD. Bypass that and it works fine just on an MCB so would think earth-neutral fault, but doing an IR test between N and E shows as a pass (>99M ohm). So unsure of...
