    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?

    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...

    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

    Seeing the PV install is going to be starting soon I thought I'd treat my bungalow to a new CU and replace old 3036 one with an 8 way RCBO board. The only RCD's in the place are the plug top type I have on the extension leads. (Only been in here for a year) I haven't had any dealings with a...

    Hi folks, Well today I attended another house to perform a bathroom upgrade. Upon visiting the mains board I noticed it was a MEM.
