Situation - local rugby club. Clubhouse has 18 external bulkhead (Phillips) fittings each using 1 G23, 11w lamp; split into two circuits each on 6amp B type mcbs. Both circuits operate via a contactor & photocell.
Problem - one circuit mcb keeps tripping, holds for three/four evenings typically, then trips.
I've swapped the tripping mcb, checked insu res etc; checked each fitting, no obvious probs.
Any suggestions?
