Testing low voltage lighting and fluorescent lights

[Mike2007]

I did assume the transforma would be double insulated construction, thus being the same 2 wire situation as a pendant light.

It will be if there's no sign of a CPC terminal.
Look for the small square inside a larger square, that's the symbol for double insulated.

Yes its double insulated. So if we have two wire at both sides and a transforma in the middle I cant do CPC continuity or 500v, but do 250v IR as a separate item completly!

Yes you do. after removing the transformer/s. So only from cu to the conductors that terminate into the transformer primary side terminals.

Yes.

The following link might help explain the IR testing.

Clear. But what a lot of tests, will take longer than the installation!
Wonder how many people test one and X by whatever lamps??
