    RCD tripping when planer turned on?

    Hi, I recently bought a new planer. When I switch it on the RCD in the garage board trips. The machine doesn't try to start, the power trips as soon as the ON button is pressed. It has a 16 amp plug. I plugged it into an existing 16 amp outlet that I use with my welder. The planers info plate...

    Meter box RCD tripping

    The meter box RCD for my power outlets in my home trips at random times, approximately every 13 hours. Have used a portable RCD box to test every appliance plugged into outlets but the portable RCD doesn’t trip. Any ideas? Faulty outlet? Faulty RCD ( it’s 25-30 years old)? No other circuit...

    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.

    RCD tripping only when high draw device and lighting ring is on.

    Hi. Wondering if anyone had any idea what might be happening. Last night I damaged a pendant light fitting by accident, not enough to stop it working. However later in the evening when my car charger started at 11:30PM the whole house RCD tripped. I only thought back to the light accident as...

    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!

    RCD tripping switchless socket?

    Hi, I swapped a 2 gang switched socket for a 2 gang switchless socket with usb ports downstairs. I switched off all the power to the house by pulling down the double red switch on the rcd box. When I turned it back on the individual rcd switch for the downstairs circuit tripped. I turned...

    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...

    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...
