UK Live neutral terminal LED bulkhead.

[Conan90]

Evening everyone,

I had new one today, a live neutral terminal on the connector of a LED emergency bulkhead. This fault repeated on 4 other units.

The neutral was being taken from a 4ft fitting next door that a new guy had been messing around with.

Any ideas why or how?

Cheers

Was the battery still connected?

What made you try that in the first place?

Yeah it was connected

A N terminal will always become live if the following are true

Live is connected to to corresponding live terminal of the load
The load is switched on
The N terminal has become disconnected from supply N.

Watch out, one of the floating N cables is likely to be live as well.

Looks to be a loss of the Neutral, I assume the fitting wasn't working.

If you disconnect N from an energised working circuit, you would expect to see voltage on the N connector of the fitting.

Leaving hanging conductors like that isn't a good idea either.

2 prong teste?

What’s the other end connected to?

The way it's shown it looked like single -point contact testing but it's not
