What would cause individual lights in a multi-light fitting to cease working ??
Obviously I don't mean Bulbs blowing - replacing bulbs demonsrates the individual fitting has broken, yet other lights in the same unit work. Now happened with different light fittings - so I don't think I just got a dodgy light unit.
It does not break the MCB / RCD when it happens.
I have:
- an extension which takes its 2 lights by extending a single light leg (I don't believe it is part of a ring, though cannot be sure).
- in addition to the original 3-bulb unit (standard 40Ws), the extension has 2 Quadrupple 50W Halogens.
Could I be overloading it ? (50*4*2 + 40*3 = 400+120 = 500W on a single wire)
- An MCB breaker (ie fuse-board replacement trips). All House lights are on a single 'trip', and it is not effected when we notice a light has popped - ie it does not trip.
Even though it's not causing Trips, I looked for dodgy connections but didn't see any, so without removing ceilings I'm stuck for ideas.
I could buy new fittings and try fewer bulbs (ie over-loading theorey) but even if that is the problem it won't tell me the acceptable limit without blowing my 3rd light fitting, and I'd prefer to save the money if possible !
Thanks in advance - Mike.
