    What test to carry out before consumer unit change?

    What test should I carry out before changing a consumer unit to ensure that it is eligible for one? I’m guessing R1 + R2 to make sure it has cpc at circuits. Say for lighting do I check every single light fitting or...? IR test I’m assuming of course so there are no trips. I’m not a testing...

    Consumer unit top knockout

    Does the consumer units top knockouts need to have stuffing glands installed even if a 50x50 trunking will cover the holes? Or is it sufficient to use a grommet or grommet strip if a rectangular hole is cut? The stuffing gland will maintain the IP rating but that will be maintained by the...

    Are Danson consumer units and RCBO's ok?

    I am in the habit of fitting 'Fusebox' consumer units. However, I notice that Danson are even cheaper. Has anyone fitted them? Are they acceptable quality? Any problems with the RCBO's? If they are 'Chint' like quality then I would rather avoid them. Chint are the only RCD's I have ever come...

    New Garage Consumer Unit

    Hi guys, Just a quick one. I’m installing a garage board in, planning on a 6mm SWA supply coming from a 32a MCB. The DB I’m feeding from is a split load board. My question is, what is the best way to move over the current MCBs to allow me to put in a MCB that’s not on any of the RCDs (as I...

    Morning everyone, I have a customer with an old CLICK consumer unit, the MCBs are DB132, DB106, DB116 etc. Does anyone know if the new CLICK elucian range of RCBOs fit this board?

    Electrician says I need a new consumer unit to pass inspection - do I really?

    He says 'it's fairly important to change the consumer unit as it wont pass the Inspection in its current state.' He's coming round tomorrow to replace it, has he given me duff advice? Cheers, Matt

    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...

    Can't find a consumer unit....!

    This is getting embarrassing - I've been looking for a sub-main consumer unit in a church for an hour now. I've found the incomer. There's a nice old Crabtree board with black breakers, one of which is a 50A for "Hall DB". It's a split level site and the hall is downstairs, and the fat 10mm T+E...
