Hi all. Today I had a new consumer box fitted. It took the electrician about 3 hours to do the job. Now when we turn the bathroom light on it trips the box. Any ideas why. It was working fine on the old box. Thanks
You need to get him back, there's obviously a fault on that circuit which should have been picked-up when he did his testing ! In fact I doubt he did much testing if he did the complete job in 3 hours!
That's terrible. Can't believe he didn't do any testing. Get him back. Out of interest is it a plastic fuse box or Metal?
Thanks for your responses. Not very happy with this. It's a metal box. He's coming back tomorrow morning to sort it out. He's registered with the NAIPT and local council. Thanks
MAte, you can't be registered with the local council. Make sure he gives you a install certificate - EIC.
My bet is most likely a shared neutral, or dodgy bathroom fitting. It sounds like very little testing, if any, was done.
The guy has been back and he said it was a shared neutral problem. All the house lights are now on one trip switch in the consumer box. Before this problem there were two trip switches in the box is this correct
Although you cant say the sparks is responsible for the shared neutral. However this problem would have shown up if the legs were tested prior to bringing the new db into service.
Its not the rarest scenario on older properties where a two way upper landing light was wired in two core for the two way switching and used the lower floors lighting feed. Just seems odd for a bathroom light to share a different floors neutral ?!
Hmmm - when I used to do rewires many years ago I always put the bathroom light (usually ho skirt) on end of run - in other words it was the last fitting on the circuit. Nowadays on my own gaff I use a dedicated rcd protected circuit for my bathrooms - this circuit also runs fan etc.
Impossible to quantify the above Gary. What does the EIC cert say in the departure notes section? You know the cert issued by the sparks who carried out the db swop.
It's safe in that it will work ok, the problem is for who ever might work on the ctt's in the future as there is risk of electric shock. I guess most sparks would prove it's dead first but not so much diy'ers.
So its okay to have all the house lights on one circuit. Is it ok, normal practice and safe as it's a new installation.
