rcd

Morning all, Whilst washing my car with our power washer the wife turned on the kettle (both were using kitchen sockets) and tripped out one of our RCDs. We have an old house and the kitchen sockets are with the upstairs and conservatory whilst the remaining rooms downstairs are on a different...

some advice needed. Before I ask advice I will be getting any wiring signed off and completed by a qualified electrician before connecting to the house mains. I just want to save some time / money by running the cables around the stud frame of my garden office and want some basic advice if...

I have connected up a new 5 KW instant water heater and have used 4mm cable of about 4 metres long to connect to the modern Wylex consumer unit with 2 RCDs using a 32 amp circuit breaker. The manual for the water heater suggests that it draws 22 amps or so, but the 32 amp breaker was to hand. As...

Hello - just want to double check I am wiring this RCD/RCCB correctly only its only got 'N' stamped on the left hand side. - it is feed/supply from top and Load from bottom isnt it? Thanks.

Hello - my sockets RCD tripped the other day and all sockets upstairs and downstairs went off - all well and good so far - but all the lights in the house were on , and I see in the (GE Euroline) CU that there is only one RCD trip and that is protecting the sockets only - the Lighting Circuit...

Hi All, On Saturday night about 1am (give or take a couple of hours) our RCD tripped, if we turn the socket breaker off then the main RCD will stay on, (lights kitchen etc) Our kitchen units are on a separate breaker so it won’t be the fridge/freezer. We have unplugged all appliances taken...

Hi guys, Having some work done in the bathroom. When finished the installer will have fitted a small heating mat under the new bathroom floor (<300W). I have a few questions about connecting it up. Previously the bathroom had a 6mm cable running from a wylex fuse box (with MCB type fuses), to...

I have a old Seaward RCD tester that tests the tripping time at 1x, 2x, and 5x of the RCD's rated tripping current. It tests 10mA, 30mA, 100mA, 300mA and 500mA rated RCD's, both at 0° and 180°. When was this type of RCD tester in mainstream use, as I have not heard of modern RCD testers being...

Hi folks, We've had some sporadic tripping of the RCD recently. Probably needs a little background in case that helps. About a year ago, RCD trips and wont reset. Disconnect appliances one at a time until RCD resets; offending appliance seems to be old cooker. Remove the cooker, everything...

I have just replaced the plug for our immersion heater. The plastic on one of the pins was melting and the smell alerted us to the problem. The RCD never tripped. I replaced the entire cable and plug as it didn't look like a great job had been done. When I opened up the old plug I noticed that...

Just wondering if the only reason some RCD's/RCBO's have functional earths is to allow the electronics inside the RCD/RCBO to remain active in the event the incoming neutral is lost or impaired casing a low/absent voltage between L & N. Any other reasons for functional earths? Are RCBO's/RCD's...

For the past few weeks, we have had one of two socket circuits tripping about once a day, including at night and day, in all weathers. The wiring is by no means new, but the consumer unit was installed only 2 years ago and the wiring fully checked. There are a few clear indications of 'DIY'...

Just wondering what BS7671 says about fixed sockets being RCD protected when being fed from a portable UPS (i.e. removable rack type UPS) when the the UPS is operating on battery mode and the Line & Neutral conductors are isolated from Earth. (Effectively a Isolated Terra based earthing system.)...

Hi, I wonder if anyone could help me. We have recently done some renovations work and my electrician has installed a new consumer unit with RCDs etc. Separate to this is a small older unit which must have been installed when the previous owners had an electric shower installed - this is the only...

I've just bought a 12ft diameter outdoor swimming pool. its a bit like this one...

Hello all, I’m looking for logic check on some work I’m planning to do, it’s quite a read so settle in, but please check my logic, anything else I should do or check? First things first, no I’m not a qualified electrician but am a competent person, well at least more competent than the...

If not, I understand it's recommended to upgrade with one, so my question is what would be the most practical installation to request from an electrician? A single RCD plug or a new fusebox? Is there anything else I should look for in selecting a new fusebox?

Hi, A few weeks ago my Diplomat 3940 oven tripped the RCD, the oven came back on after I reset the RCD but fan element wasn't heating up. The oven still worked on every other function so I assumed the fan element had blown. I bought a replacement element and fitted it (the old one was visibly...

I hope it is only MY logic that is failing... ...and that YOU can figure it out! This happens to be in Cyprus, but it could just as well be the UK or elsewhere. Immersion heater (IH) connected to Neutral-Earth fault. I installed a new one (Backer 314C, 3kW), ran for an hour then RCD tripped...

Just a RCD operating with the front cover removed, 20w load connected between line out and neutral in. Shot at 50 FPS using my Panasonic HDC-SD600. Also before the video, I wired a Plug to the Input of the RCD and a 20w CFL lamp to the output of the RCD, I then wired a switch in between the...
