Help!
Went to job at end of day today. Client reported lighting mcb tripping. 1 fitting had been leaked on, and 2 others she said had been flickering on and off. Just one lighting circuit. Tested to find dead short between p and cpc. Will need to go back and investigate further.
HOWEVER, the 2 flickery lights were on 2 gang switch and when testing I got 230 on all cables (lives and switched lives). This was confirmed at the lights, which were 'on' even if the switch was operated. The client tells me that the lights have worked before OK. The 2 gang switch appeared to have a live link and one of the gangs is two way. Neutrals looped at lights. Switch operating OK
Any ideas what could be making the switch lives live? All other lights operated OK. Could it be linked to the p-cpc fault? Cables run in a mixture of steel conduit and plastic trunking.
Ideas/thought's gratefully received
