    UK Local RCBO protecting ring final alteration.

    Hi I completed a job recently where a hotel reception had a new desk fitted. The old desk dado was supplied via an RCD spur from the existing ring. This ring is fed from one of the very old Merlin single phase boards which I’ve been told you cannot retrofit Schneider ic60n RCBO’s in. I had to...

    RCBO identification

    Take a look at the 8 live circuits, including lighting made off into 1, 20A MCB I found while carrying out an EICR inspection today! Does anyone recognise the manufacturer of RCBO?

    Wylex RCBO

    Hi, this Wylex NHXSBS1BO6 has failed and I'll get a new one but I don't know if you see that the live is the hole at the back and the connection is really deep! Seems a stupid design. Also when fully tightened these RCBOs have a small gap? They just seem garbage to me. Can I use another brand...

    RCBO wiring direction?

    Hi All - I have a new-to-me boat and I'm trying to better understand the electrical system. I'm sorry if this is the wrong forum, but it's a French built boat using all Hager MCBs and switches. None of this stuff exists in the U.S., afaik. I'm not on the boat at the moment to test but from...

    individual RCBOs or a main breaker RCBO? and what trip level 10mA or 30mA

    I have the feeling that I might have small currents running in the house. So first of all, I am considering to get a leakage clamp meter. But besides of this, I am also considering to replace the breakers with RCBO. But then the question, should I go for indivdual rcbo or just replace the main...

    Will the mini (or larger) RCBO fir in the this starbreaker board?

    2 questions.. 1. Will the mini Starbreaker RCBO's fit in this board? Below is a picture of the board and also the type of RCBO I want to fit in? Thanks :) 2. The existing 100mA RCD is type AC. The RCBO's will be Type A. I have never quite got my head around how this 'incorrect' selectivity...

    UK RCBO Testing

    Just wondering if someone could help provide an explanation as to why this might be the case when testing an RCBO. Testing the RCBO at the DB recorded a value of >300ms (test probes connected N&L load side, and E bar), yet when running the same test at a socket-outlet of the same RCBO tripped at...

    RCBO curve

    I’m probably going to look stupid here, but it will be worth it if I get the answer 😆, as I can’t fathom it out. I’ve never really thought of it before, but….. A circuit breaker comes in curves B, C, and D. Now we all know it’s mostly to do with the in rush of current ( layman terms) but the...

    RCBO installtion in old MCU following EICR Report

    Hi, I recently had an EICR done at my property which unfortunately was unsatisfactory. So the electrican advised a new fuseboard from BG General or Fusebox but he advised there will be alteration to the wall as the unit is flush mount inside wall and the mounting frame is glued in with screws...

    RCBO or not?

    Folks. I need to install a defib unit outside on a wall. Does this require an RCBO or not, just wondering as the unit has a small heater within and should it trip out for any reason other than under fault conditions (it is in a dampish environment, a harbour) it will get damp. So MCB or RCBO...

    After a New Consumer Unit, now I need EICR & 100A DP Isolation Switch

    Trying to organise a CU replacement at home. It's a 1930s property. It's got a 10way CU but with no RCD protection. Was after a larger unit with full RCBOs. Every Sparky I've spoken to has varied in their suggested plans. 1) Some say do an EICR first, others happy to just go straight with a...

    Can you feed a RCBO with a MCB

    So here is the thing Rhere is an old MEMSHIELD TPN+E Board that is pretty mich obsolete. The only place that sells their breakers would be Ebay right. After having EICR done on it it's been flagged that It requires RCBO/RCD for sockets right. So here is where we are at It's not really...
