rcd

In one of your forums someone stated that a split-load CU protects circuits by RCDs and a dual CU doesn't. So what protection DOES a dual unit provide? Surely ALL circuits are protected by an RCD even if several circuits use the same RCD?

Hello, I'm in the process of planning a small garden office build. I'll build the office but pay an electrician to install the electrics. However I just want to understand the potential extent of electrical works required. I currently have a BG dual rcd board (I know BG isn't great but it...

Hi all, Want to know what sort of IR readings I should be expecting between the case and the various elements (with the elements disconnected of course) of my Electrolux Steam fan oven as in recent times it has been tripping the RCD. :rolleyes::( I have had it switched off at the local...

Hi guys 'n gals. In a nutshell what would you recommend from the consumer unit, 30m to a garage, CU in there and out to an old oil filled arc (stick) welder capable of going from 30 amps up to 180 amps. At the moment I have CU in the house with 45amp Type C RCBO, 10mm T&E to garage 30m away...

Looking at that eyesore of our CU, I noticed that the RCD (which protects only kitchen, upstairs and downstairs rings) is rated for 60A when the circuit breakers are 32a each. Is that a problem? I am aware that it is unrealistic to have 3*32A=96A at any given moment, but it is theoretically...

We don't generally use the immersion heater so I'm planning to wire it into a Solic 200. First - to make sure it is working I removed the old time clock and controlled it direct from the 16A MCB switched spur - 80A RCD tripped. Isolated the tripping to the immersion heater, as wiring a light...

Good Morning All, Im wondering if anyone may be able to help or advise please. I have an issue I believe is tied to a leak coming from the combi boiler (Biasi Riva Plus HE M296 28SMC, 2015 Model): Last night the RCD on my home electrical system consumer unit tripped, after much hunting...

Hi. Wonder if anybody can help with this please? We have a baumatic p632ss single oven. It seems that when it hits the temperature set on the dial, it trips the RCD. If I switch off at the wall, I can then reset the breaker. Otherwise i have to wait a minute or so. Setting the temperature...

Here's my problem: I hope I've isolated the appliance that causes the right hand side of our consumer unit RCD to trip. If we leave the dishwasher on alone we can come home to find the CU has tripped. I flip off the offending circuit (washing machine, tumble dryer, heating boiler, dishwasher)...

Even with the power disconnected. If you hold the trip switch in reset position, motor starts and runs perfectly until you release the trip switch (which is inside the switch panel, not accessible without dismanteling the switch unit). No signs of excessive heat, no bare wires, no burning...

Hi, I’m not an electrician so won’t pretend to understand anything. But I’ve just lost all power to my flat, nothing tripped off but the power had been intermittent on and off when ever it rains. I’ve visited the meter boxes and there were a smell of burnt plastic like when a capo blows and the...

New BG domestic box has been fitted. Everything in box works ok, without tripping, except the led lighting circuit, which trips RCD every time wall switch is activated. Lighting circuit trips either B6 RCD it is connected to, or larger in line 63A RCD. LED lighting circuit works Ok when MCB...

Hi all, I have recently replaced one of the sockets in my house and for some reason it is tripping the RCD on the consumer unit. Can anyone help please? A little background info, Following some recent works on the house I have had to replace an electrical cable to a socket as the original...

Hi all, looking for electrical advice. Have a Bosch single built under oven (approx 6 yrs old) - has started to trip out the RCD on modern fuse board but can't find a pattern to it. Mainly happens when been on for a while with lots in (sunday roast etc.). Each time I have been present when...

Hello, The house that we have bought has a CU that was last tested in 2016. It has a 100A supply Main Switch and then a single 63A RCD that protects 7 x MCB: 1 x 40A Shower - 10mm Cable 1 x 32A Cooker - 6mm Cable 1 x 32A Ground Floor Ring Main - 2.5mm Cable 1 x 32A First Floor (small) +...

Hi All, I’m doing a DIY project but needed some advice before I comitted and would really appreciate any help/advice you can offer. I have recently moved in to a new house and wanted to put in electric underfloor heating in the hallway. The property is a bungalow and all the wiring goes in to...

Curious about how those on here handle testing RCD's when doing EICR's or MWC's? If you have several circuits protected by an RCD as is often the case, do you test the RCD on each circuit it protects or just once for each RCD what is ideally done with no loads at the distribution board. In...

Just been reading my copy of BS7671 in my spare time, regulation 710.411.6 says that an IT earthing system with a IMD must be used for group 2 medical locations. Does that mean that expect for devices covered by reg 710.411.4 in group 2 locations, all medical devices must and always be fed from...

Hi All, I have a socket in the bathroom which has gone dead. I can tell this is not on a ring main as it only has one set of wires connected to it, could anyone tell me how I would find out whether it is connected directly to the CU or it is a spur off another socket. I was going to open all...

Trying to work out if the DiLog DL9118 MFT tests Type B RCD's? The instructions say it tests DC RCD's of both selective and non selective types. Is this referring to Type B RCD's or just to pure DC RCD's and not AC RCD's what can detect DC bias? Am I also right in that 2-Wire no trip loop...
