    RCBO Trips After 10 seconds

    Hello - I wonder if anyone can give me some advice about the following: My house has two outside lighting circuits (front lights and back lights). These are controlled via separate switches which are connected to a 6amp RCBO (30mA B curve) in the CU. Each circuit has 20x GU10 LED spots at 5w...

    Sources for SPD RCBO type A boards.

    Hi all, With Amendment 2 here has anyone found any good suppliers for SPD and RCBO domestic boards? I've found online a BG SPD + 8 RCBOs for about £190 which is about £40 cheaper than the local wholesaler. Are there any better deals out there for decent boards (I've seen 'Live' offering online...

    Electric shower case: short circuits (?) and RCBO

    Hello, I have just posted in the Electrician's section one photo and two videos of what I believe to be a dangerous situation of short circuits happening within a shower unit. You can see (also here attached): 1) Extensive burn marks on the plastic cover; 2) A vast amount of water leaking from...

    RCBO tripping even when the switch is off

    Hi I have an RCBO that keeps tripping. It is a new install to feed an EV charger with an isolation switch between and is around 5 foot from the switch board. The RCBO trips at random when the switch is off to isolate the EV charger. It has not tripped when the charger is turned on. I have...

    20amp RCBO neutral fly wire only 1.5mm

    Why does a 20amp RCBO come with only a 1.5mm neutral flywire when you are driving a 2.5mm power circuit. Aren't you creating a choke, & potential voltage drop. I appreciate it can carry 20amps but it doesn't make sense to me

    Isolation switch vs RCBO

    Planning a kitchen design with a 7.2KW induction hob. The hob will be on its own separate circuit protected by an RCBO. Best practice seems to be to have an isolation switch for the hob but the ideal switch position would be directly underneath the consumer unit. Given that I would be able to...

    Advice yes or no? On RCBO fuse installation?

    Got a duel wylex RCB & RCBO board installed some time back. It has space I think for 3 RCBO's. The spark suggested putting the garage feed and the shower feed on rcbo at the time I stuck with the RCB option as a false saving but am now thinking of doing RCBO for garage and shower a suggested...

    have been to a convenience store and the rcbo circuit that is on a 32amp fuse keeps on tripping when it rains heavy. The circuit has a warmer plate, food warmer, ice cream freezer and a drinks freezer running on the circuit. I disconnected the appliances and plugged them back in and everything...

    Help please on a sub consumer unit fed from RCBO

    Long time lurker so this may be my first question. I am a qualified electrical engineer, but in aeronautics not domestic installations, and I may therefore ask silly questions. We have purchased a property that is unfinished, and where the electrician went bust before the installation was...
