Just been to test off a lighting circuit.
r1+r2 fine at 1.01 ohms
IR passes at +200 mohms
Voltage at loop and switch line when closed is 240V
Zs at the live loops OK
Zs at switch lines OK
But I am getting a voltage across the switch line when the switch is open. There are three lights on circuit two are 1way and the third is 2way. The two 1way lights are reading 19v & 17v (these two are 18w 4 pin DD 18w 4 pin DD fittings) The third 2way is reading 40v at the switch line when switch is open. Readings have been taking between switch line, referencing across both CPC and Neutral, still the same reading regardless.
When the lamp (GLS B22) is installed to the third light lampholder, the voltage drops to zero.
I have tested the switch line at the switch, also when open getting same readings. I have disconnected the lampholder, made no difference.
A bit puzzled?
