Mornin All,
I was called out to a lighting failure. The upstairs lights in a large house caused the 6 Amp. M.C.B. to trip off and it would not reset.

After removing all lamps and carrying out insulation resistance testing the fault was located on an external L.E.D. floodlight. The L to N resistance was about 4 Ohms.

Why don't these type of fittings have an internal fuse or other device to disconnect just them if they short circuit? The light was at high level and was not easy to access. It did not have a local or even a remote isolator so that the householder could operate it and disconnect it. Local or internal fusing would prevent inconvenience.

What are others' views.

Bye,

Z.
