    Wanted Old/Used/Faulty BG RCBOs for wiring practice rig

    As title; am after old/used/naff BG RCBOs to throw one or two in my wiring rig and as they wont be used IRL I can't really justify the £10-20 price tag new ones attract so figured I'd be cheeky and ask. On a side note; do many sparks reuse old/removed kit if its still in workings order...

    Hi all, Does anyone have any apps/conversion charts that are handy for swapping out circuit breakers to rcbos without relying on electrical stores to check conversions/fittings. Im quite fresh out my time so a lot of the common ones are not common to me as yet. The problem I am having is, I...

    Recommend me a small CU with DP MCBs / RCBOs

    I need to go shopping in the morning for a small metal CU, about 5 outgoing circuits, but they have to be fitted with DP OCPD including some C-type. One overall RCD is OK but if I can get suitable RCBOs that is a possible. It's so rare that I fit a small single-phase board, I've no idea which...

    Domestic Questions about choosing RCBOs

    Hello, I have been reading the topics on this forum which have been very helpful.

I have gathered that...

    6kA (Not 10kA) RCBOs in commercial TP boards: Why not?

    I'm fitting two replacement sub-mains panels as part of a long-term upgrade from split-phase to three phase on a part-domestic part-commercial site (my own gaff). I'm using all RCBOs because I like them, but am less keen on the cost of the commercial variants ... Fellow spark says one MUST use...

    Class A RCBOs - list of manufacturers

    I'd find a list of manufacturers who are currently producing single module class A RCBOs (and perhaps class A RCDs) quite useful. To my knowledge so far there are: Hager Doepke Schneider Does anyone know of any others?

    Electrician Changing garage Mcbs for Rcbos

    My garage has a small consumer unit fitted with elcb and mcbs for the socket and lights. After cutting through a circular saw cable it did not take out the garage elcb but the elcb in the house consumer unit. If I get an electrician to changed the mcbs for Rcbos would this prevent the house elcb...

    Board change (RCBOs) Lights trip sockets

    Evening all, I changed a board today in a ground floor flat. 3 circuits with separate RCBOs (Shower 40A, sockets 32A, and Lights 6A) Switching on any light switch causes the both RCBOs for the lights and sockets to trip. Insulation resistance results are in the 100s between conductors on...

    Converting split load CU to Main Switch (RCBOs)

    Hi folks, i have a 16 way British General CU which was configured as split load. I'm converting to all RCBOs which is fine apart from one small detail, i don't have a single neutral bar long enough. The earth bar is fine - plenty of ways for CPC doubled with RCBO functional earth. The neutral...

    100mA RCD on PME system

    I am going to a job this afternoon, new shower circuit. I noticed yesterday that the Wylex CU has a 100mA S-type RCD as the main switch and all the circuits are on 30mA RCBOs. PME system as far as I could tell (certainly not TT). Didn't give it much thought then, but was thinking about it...

    RCB or RCBO in a Distribution Board.

    61009-1 or 61009-2 RCBO's

    Afternoon guys, Just wondered what the difference is, if any between a 61009-1 RCBO and 61009-2 RCBO? Are the characteristics different for any reason for different applications? I noticed that 61009-2 came out 1995? Thanks

    Sports pavilion rcbos or rccb incommer

    Hello guys. I was asked to quote to replace a 3 phase db in a sports pavilion. All cables are twin and Earth in the wall.

    S-type RCBOs

    Does anyone make S-type RCBOs? For discrimination you should use an S-type RCD to protect a sub-main feeding a CU with a normal 30mA RCD or RCBOs. This can be handled with a 100mA 100mSec S-type RCD. It would be convenient if this were combined with a type B or C 63 amp MCB. This is in a...

    All Rcbos

    Someones told me that to comply with the latest regs then a split load board with half the circuits as rcbos & the rest on mcbs with an RCD is no good & all rcbos is the way to go. I can see the point but it seems overkill ???
