lighting circuit 142 volts phase to neutral and earth

[TONY144]

Has anyone come across this problem I have an idea someone may have connected from a strapper any suggestions?

cheers

Whereabouts on the circuit are you testing.

 

[TONY144]

at the light

 

[Gaz the Sparky]

what are you using to measure this

Martindale voltage testers need to be connected between either phase and earth or phase and neutral to make a circuit to indicate voltage

more info is needed

these are some things i could think of off hand

could be a loose neutral but that would me that the neutral is live

I think that it could be a short circuit in the cable somewhere where the insulation is down

it wont be the strappers of a 2 way lighting circuit because there is no neutral at any of the switches so you could only get voltage across phase and earth

 

[TONY144]

fluke true rms

 

[ricicle]

Are you testing between switched live and neutral and is the switch in the on position.Does the light come on at all?

 

[Spark123]

Are you testing the switch live with the lamp removed using a multimeter?

 

[TONY144]

yes spark 123

 

[TONY144]

correct me if i am wrong but a reduced volt drop to me would suggest that there is a series connection somewhere any thoughts please anyone?

 

[THRIPSTER]

Is there a dimmer in the circuit?

 

[TONY144]

yes there is does this make a difference the light is controlled from a dimmer which now thinking about it does vary the voltage i believe.

 

[Steve]

take the switch off, and measure between the permenant live and the earth terminal.

cheers to all who replied to my querie

I agree Secure
