    rcd tripping

    Has anyone found the rcd tripping even when on no trip on a new circuit. Cannot find a fault on the circuit. Tried on another socket circuit in the premises & that tripped as well.

    The RCD is tripping after few minutes of the light is on.

    I have done the new wiring in my garage with a new distribution box having a RCD and 4 MCB's. And now when I switch a light on, it works for 5 to 10 minutes and then suddenly RCD trips. Please advice what I can do to find the fault. Many thanks.

    Delayed tripping on RCD

    Not even sure where to start with this… Got a split board RCD which is tripping after 10mins of being ON. Never had this before. I thought I identified the circuit with the fault (RCD trips immediately when circuit on) but looks like a fault on more than 1 circuit Customer just had a brand new...

    UK RCD tripping explanation

    As a keen adult learner any help would be appreciated I understand that an RCD trips when there is an imbalance detected between L and N. If a 30mA RCD is monitoring several circuits (in a split board for example) and one of the circuits is protected by a 32A Type B MCB. I'm trying to...

    Faulty RCD tripping on the button but not via the tester

    What should you do if a client has a CU that is a split board protected by 2 * 63Amp 30mA double pole RCCDs, you took Zs and tested both RCCDs by their buttons before starting work. But on completion of work, one of the RCCDs, when tested via tester, would not trip, the other operated as expected!

    UK RCD tripping when using loft socket.

    Afternoon all, I have an issue with the loft socket. When we moved the previous owners had a 2.5mm cable going up from the CU Via FCU however, the wiring was old and did not have earths(they cut them off). So I decided to completely rip out the old wiring including unnecessary spur and put...

    Solar New Solis inverter trips house electrics

    Hello there I have just installed a new Solis S6-GR1P3.6K-M-DC Inverter - this replaced a 10 year old+ Sungrow inverter that failed/out of warranty! None of the wiring set up has changed other than a new AC plug for the Solis inverter. I have a 16-panel 4kw system. It seems, when the inverter...

    Real life examples of RCD fault

    What’s a real life example of an imbalance between live and neutral? For example, a faulty tumble dryer can trip a RCD on a split board - so I would assume there is an imbalance because of the difference in the magnetic flux between the Live and Neutral coils. But what would be the actual...

    RCD tripping on test

    Hi, while testing the new board I installed I got to the live testing at the sockets one of the RCD's kept tripping during the loop test, the other ring tested fine so it's not the tester, the insulation tests where all good. Unfortunately I didn't have a residual current clamp meter with me, to...

    Shared/borrowed neutral?

    Hi, I have an ongoing issue with an RCD which keeps tripping when bathroom light (not on RCD) is turned off. The issue doesn’t happen every time the bathroom light is switched off but only ever trips when I turn it off. It happens mainly at night and there doesn’t seem to be much of a link...

    RCD tripping when socket is turned OFF

    Hi, No electrician background here, so novice question! I have a new (<6 months) plug socket that whenever I switch it OFF it trips the RCD on the fuse box. I’d previously had an issue with the RCD and ‘socket’ switch tripping (all sockets are on one switch on the fuse box) which was traced to...
