Hi all,
Wonder if any one can help with this problem. Had a bulb blow yesterday morning and half the house went into darkness. Went to reset the MCB only to find it hadnt blown.
Initially i thought it was the MCB so changed that over with no joy.
On testing the voltage at the switch i find
L/E = 250 volts L/N = 8 volts N/E = 230 Volts
I have isolated the fitting where the lamp blew yesterday, with no luck.
There is a hard wired smoke detector on this circuit ? will this have an effect.
Any help in troubleshooting this would be greatly appreciatted.
