    UK RCD rating in Sub board less than suppy protection

    I have a 40amp RCD downstream of a 50a MCB (10mm csa cable) should the MCB be lowered to protect the RCD from overload? If so why does this not apply to RCD devices in Split Load boards

    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?

    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...

    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??
