Newbie screaming for help with constantly tripping RCBO.

[Cyril Eaton]

Hi - I would get hold of some extension leads sharpish and get the freezers back on power. It will be tough to find the fault(s) without test gear.

Power has been temporarily restored to the Freezers, thank you.

 

[Cyril Eaton]

Well firstly thanks for your service, I have high regard for service personel. Now that aside you should know better as an ex spark, changing a board and connecting existing circuits to it without testing is literally appalling, sorry but there you are, you will get the odd nice comment but it will be few and far between I am afraid.

I'm not looking for nice, but helpful is useful.

Where have you connected the neutral...into the RCBO or to the neutral bar?

 

[Cyril Eaton]

So you are familiar with Part P of the building regs then?

I am, and that's part of the plan. Mostly I wanted something safer than what was there - and that's still my aim.

So did you notify BCO before you started? before you paid their fees?

Too true, there may be beer in the fridge.

only philistines and lager louts keep beer in fridges.

I keep my cider in mine Tel, the farmers toe nails harden in the cider and they are easily removed when cold mate.

I'm replacing an old MEM Fuse Board in my garage with a Small CU. The power was supplied from the ground floor ring main, so I've removed that and added a separate circuit in the main CU with its own RCBO. Problem is, the RCBO trips every time I turn something on and I can't understand why. Apart from the supply cable - main CU to new CU - the cabling is exactly the same as yesterday and was working so I can't understand why there's a problem. Help desperately needed as I have 3 freezers in the garage.

What sort of main CU do you have? is it a relativley new one with 2 RCDs?

 

[gazdkw82]

Does it trip with no load? I.e nothing plugged in and turned on?

If yes then I'd suspect a short within your new (notifiable) circuit.

If not then turn your appliances on one at a time and narrow down the offending item.

I trained as an Electrician with the RAF in 1975 and I've been doing it since.

You might have trained but did you actually qualify or fail?
I call bull**** on this, if you really were an electrician you would have the knowledge and experience to not get yourself in to this situation.

Problem sorted. Everything up and running.

Problem sorted. Everything up and running.

and what was the fault?

 

[Cyril Eaton]

and what was the fault?

The old strip light. I had planned to replace it at some point in the future. Just had to bring the plan forward a bit.

If the main cu us a split one are live and neutral on same side?
