HI Norman Sounds like there is a problem with this light. As Bogdan says your new board with RCD is very sensitive and will detect even minor faults very quickly and they can sometimes be a pain but it is for your safety. A lot of people find out they have problems they didnt know they had until they fit a new mains board. Ask the electrician to return to return and sort the bathroom light.It shouldn't cost that much to sort Hope this helps Russ

Hi, The electrician that fitted the new board should have tested the circuits for this before changing it. Did he give you an installation certificate? Assuming no extractor fan working off this light fitting. Sounds like the switch wire cable for the bathroom light needs replacing. Possibly a neutral to earth fault. Hope this helps, Andy

Hi Norman this is a common problem once a new board is fitted as the RCD is more sensitive than the old style boards! as it also senses neutral to earth faults. which could be a fault in the cable, faulty shaver point, faulty light fitting, faulty dimmer. Ask tye electrician back to do a full test on the circuit. Is it definitely the lighting circuit? hope this helps dave

Hi. Old fuse box was without RCD so even in small current ,,leak,, due to humidity or old cables no chance to tripping fuse . But in case to use RCD in new fuse box - (very selective device) which recognise even small current leak or cable fault , reaction is quick . In finally my advise : 1. check you have correct IP rate of lights in bathroom 2. check wires condition . You need electrician with tester . ps what about bathroom airfan ? where is connected ? regards Bogdan Banasiewicz PROTON
