Hi. I'm looking for some guidance on RCD/ RCBO selection for heat pumps. The heat pump manual states: The RCDs follow the standards and regulations but may be not applicable for heat pumps that have high frequency ampere peaks caused by the inverter technology. Therefore, RCDs need to be...

I have an old MK Sentry Consumer unit fitted with LN59xx MCBs: I want to replace the LN5905 5A MCBs with H6832s (6A, 30mA, Type A) RCBOs so that the lighting circuits are RCD protected (given that I cannot find an RCD to fit this CU). I can see that the busbar isn't compatible, so I will...

Hey there! A few weeks ago I posted on this forum asking for advice on converting my existing split-load Hager consumer unit to an all RCBO consumer unit. Huge shoutout to the folks who provided some helpful feedback and shared their wisdom on competencies and qualifications. Your input was...

Hi DIYers! I just moved in and I needed additional breakers in the Hager Consumer unit (VECOS33-6H), but there was no space and no way to replace the unit with a larger one. Since it's a split unit, I freed up space for additional breakers by replacing the existing ones with RCBOs and removing...

Hi All I need to install a coffee machine onto its own circuit. The existing connection was from an FCU protected by a 20AMP breaker @ the CU on the RCD protected side of the CU. We have had to relocate the coffee machine. There is currently an unused storage heater connected to an FCU that...

Hi Guys. I’ve got a 12 way Volex 17th Edition split consumer unit that currently has 4 MCB no RCD (for electrical heating) and 5 MCB with RCD protection for lights, immersion, Oven / Hob, Final Ring, & radial socket. There’s a guy on ebay selling New Old stock Volex RCBOS’ of the right...

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...

Hi all, I am moving some downlights in the Grandparents bathroom to inside a new shower cubicle. Old mr16 downlights from zone 2 have got to go. In the situation we are having i cant find any 12v ip65 downlights anywhere. toolstation had a clearance and not to be restocked. 3 options i thought...

Hi all, Hoping you can offer a novice some advice. We've had the house re-wired with a new fuse box with RCBOs. Our electrician left the build a while ago and has sadly passed away since. Before he left he didn't finish connecting up the SWA cable running to the shed, so I've done it using some...

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...

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...

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...

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...

MK have issued a recall for some of their B and C curve RCBOs CLICK HERE FOR DETAILS The recall notice states We have identified a potential safety issue with the manufacture of a limited number of MK Sentry RCBOs which may result in the device failing to trip under certain very limited...

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...
