Lights and indicator lights flicking

[Gary1255]

Hi All - I was called to a customers house this morning. All their lights and switch indicators are flickering. I checked IR - all good. I had one circuit at a time e.g. sockets and indicators flickered. I had just light circuit on - turned lights on one room and lights flickered. Tried another room and lights flickered. Incoming voltage at the board ranged from 230v to 248V. I put my clamp meter on each circuit and amp stayed constant if lights turned on for example. All the lights are LED spots of various makes in each room but that does not explain socket indicators and even fridge light flicking. I tightened all screws at board also Am I missing something - any suggestions gratefully received

Check the incoming neutral.

Yes, does sound like bad connection on the supply side. Especially if you are getting voltage variations like that. Tighten everything that you can access. If it still is happening, you'll need to get the DNO to investigate, it could be in the cut out, or buried underground outside..

Many thanks - I tightened everything at the main switch and still variance - I did tell him to contact DNO - I was just having one of those doubting moments
