Electric supply

[Duncan]

Hi
Advice needed on electricity supply, I've had my house totally rewired and been issued with part P cert, over the last few weeks i have had a problem with flickering lights ( all over the house not just one light ) - is it a supply problem or is there anything i can check in the consumer unit , cheers for any advice

Hi Duncan,
A simple diy test to see if it is a supply problem is to plug a table lamp into a 13 amp socket and see if that flickers. Are all the lights on one circuit breaker?

Hi John, thanks for your reply.

I plugged a bedside light into a socket last night, and didn't have flickering on it although I did on the main light (so I guess that proves that the problem is on the light circuits only).

I actually have two lights circuit breakers - one upstairs, one down (well that's what the labels say!).

Hi Duncan,
Best option is to get your contractor back.

If all other circuits are ok (i.e. the bedside lamp in the ring main) it won't be your mains supply. There could be a loose connection in the neutral lighting connection strip in your consumer unit even with more than one lighting circuit if they are connected to a common terminal screw on the strip,

your all posts show that you all have good knowledge in this field, Actually I have installed smoke alarms in my home and I want to supply them all the electricity back up which could charge the batteries when it's go down. so how can I do.........

Hi,
It all depends on the type of smoke alarms you have installed.
All the battery powered smoke alarms I've come across are just that, battery powered - you can't connect mains to them and the batteries are not rechargeable.
Mains powered smoke alarms include a rechargeable back-up battery which keeps them working if the mains goes down. Fitting mains powered smoke alarms as a new installation would be notifiable under building regs part p - so you would need to get a certified electrician in to do it.
Possibly not the answer you were looking for, but I hope it helps.
