    PSU works with a multimeter attached, but trips the safety without it.

    Hey, I want to use an old xbox 360 PSU- 12V 175W output- for my 12V sup pump (pump/air compressor). When I connected the PSU to the pump directly the SUP pump worked without a problem until it switched to the air compressor( it does it automatically after the pressure reaches 1 psi. The moment...

    RCD trips with all load breakers open

    My circuit panel has two banks of breakers, each bank protected by an RCD. One of these RCDs has been problematic in that it trips intermitantly. A few months ago it became so frequent that we had the RCD replaced. It would trip regardless of what load breakers were shut or open. No fault could...

    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...

    Dehumidifier trips breakers on one panel but not another

    Hi everyone. I have a basement that was finished years ago. The basement is on a separate panel than the rest of the house. For years I've had several dehumidifiers die various deaths in my basement. I thought it was just bad luck, but now I'm not so sure. My latest dehumidifier started tripping...

    RCD trips when screw touches lug

    DIY question. I have been changing old metal socket faceplates to the normal plastic ones. All are working fine except the faceplate of a fused switch. Everything works fine when it isn’t screwed. It is a fused spur for a light in the conservatory. The light works fine when the screws are off...

    Cooker RCBO trips when any other RCBO tested?

    I will start with apologies, as I have not thought this through very much (at all) yet and have just sat down with a beer.... meaning I thought I'd ask the collective. CU change today. I did my pre checks and I knew I had a major IR fault on the cooker circuit (N-E 0.3ohms, yes that figure is...

    Washer earth trips unless it is rocked back & forwards aggressively.

    Very appreciated forum. Washer earth trips RCCB unless it is rocked back & forwards aggressively. This is a struggle. One brush had worn excessively and tripped and changed. I wonder if there is excessive wear due to uneven commutator causing a pile of debris bridging to brush housing? Any...

    Isolate circuit but trips fuse board

    Hi Weird problem. I’m replacing plug sockets. I isolate the circuit for the particular sockets at the fuse board so it is safe to swap out. All good. Suddenly the RCCB for all sockets - not just the circuit of the sockets I have isolated - trips. Why is this happening? The RCCB doesn’t trip...

    Device randomly trips ARC Fault Breaker

    if my brand new fridge is connected to a circuit with an ARC Fault breaker, and if the circuit has ONLY ONE OUTLET on it (the one to which the fridge is connected), then what are the most likely causes of RANDOM arc fault trips. It'll stay on for a week...then all of a sudden...it'll trip (even...

    Hi all, so just moved into a new property, the light fitting/rose was removed from the living room, nothing looks to be shorting (But there is a single neutral with no connector block?) but the breaker trips straight away. There are 4 fittings on this floor, none with bulbs in, none with any...

    How to keep power trips isolated and not trip the whole place when testing faulty appliances?

    Having some 1400W 230V heaters to test and repair that have a power trip problem. I've unplugged all the connections and open them up one by one to identify the part that is causing the trips. Everytime it trips, it trips the whole place through the main circuit breaker. How can I do it safely...

    Two Lutron RA2 Switches - both switched on, and RCD trips, either on and no problems

    Only a DIY'er here, usually safe and competent enough to fix straight forward problems, but this one has me stumped. I have two outside lighting circuits running through Lutron RA2 dimmers. Both go back to a Hager MTN106 RCD. All been working fine for over a year, but now the breaker keeps...

    RCBO Trips After 10 seconds

    Hello - I wonder if anyone can give me some advice about the following: My house has two outside lighting circuits (front lights and back lights). These are controlled via separate switches which are connected to a 6amp RCBO (30mA B curve) in the CU. Each circuit has 20x GU10 LED spots at 5w...

    20 amp breaker trips

    The 20 amp breaker that protects ceiling can lights trips with increasing regularity. It takes a few tries to get it to reset. The can lights (led bulbs installed 2 years ago) are on older dimmers. They worked fine until recently. Should I start by replacing the breakers, the dimmers, or...

The circuit has a warmer plate, food warmer, ice cream freezer and a drinks freezer running on the circuit. I disconnected the appliances and plugged them back in and everything...
