    Do Distribution circuits require RCD protection?

    I'm doing a college design project and need to choose a suitable range of circuit protective devices for the whole contact. I've chosen and already done all the protective devices for all my final circuits but was curious if the distribution circuits need RCD protection aswell. The project...

    Maximum Zs on circuit protected by RCD - 1667?

    Does a RCBO protecting a single circuit mean it can have a maximum Zs of 1667 Ohms since it's being used as fault protection?

    Does anyone know what RCD fault he is talking about

    Hi Basically I have visited a youtube link of another electrician and he is talking about how many electricians find RCD fault very hard to resolve and he mentioned it takes less than 3 minutes using the method he mentioned but not completely hence its really puzzling me so if anyone could...

    UK RCD sockets regulation

    Can anyone tell me the latest regulation for RCD protection on socket outlets, I believe it's required for sockets up to 32A but I'm told it applies to all socket outlets, we have to install a 63A 5 pin socket located outside. Thanks in advance

    N/E fault IR=0 - RCD won’t hold

    Hi all, After some options/opinions on fault finding N/E fault on ring final as fairly newish to being out alone. Customer wants to upgrade from rewirable CU to RCBO so fairly old wiring but no signs of cable breakdown or anything totally messy on inspection. This circuit basically holds...

    EIC additional circuit main switch/switch-fuse/circuit breaker/RCD

    When doing an EIC for an additional circuit (which only covers that circuit), does the 'main switch/switch-fuse/circuit-breaker/RCD' section refer to: a) the MCB you're adding for the new circuit b) the existing main switch (whatever it is) for that board c) [if the DB the circuit is added to is...

    EICR question, OLD AC RCD- code 3 or no code?

    With regards to Regulation 531.3. 3 of BS 7671:2018+A2:2022 Older AC type RCD's are prone to being blinded by dc leakage from other items plugged in to the property. In other words this RCD may fail to operate when other electronic items are plugged in which leak DC in to the mains. Regulation...

    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 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...

    I've got a dual rcd mk sentry board that I want to inverter into an rcbo board. If I link the two neutral bars from the main switch is this OK to do regs wise? Thanks

    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...

    PV and not and RCD protection.

    Had a customer ask for RCD to be changed to Type A as he has had a company install a PV unit which they have left with the spur switched off as new regulations state that PV units must have a type A RCD 🤔. Has anybody else had this situation??

    UK What’s the correct way to enter RCD’s on a split load board on a schedule of test results?

    Would entering each RCD as a line on the schedule of test results be correct? If so, what would be entered in boxes such as Zs?

    UK Can you add additional sockets to non RCD protected circuits via RCD spurs or sockets?

    Evening all, If a socket circuit is not RCD protected via an RCD/RCBO and there isn't the option of fitting an additional RCD enclosure or fitting RCBOs, is it permitted to add additional sockets to the circuit via RCD spurs or additional RCD socket outlets? (type A of course)...if the sockets...

    3 phase RCD question

    Hi everyone, each leakage question here. I am needing to run some LED screens, professional type, not TVs. These are 500mm x 500mm panels and traditionally have 2/3mA leakage per panel. So we generally have a 63A three phase distro with a 300 mA on input and multiple outputs protected by 30 mA...
