Induced Voltage LED / Steel Trunking

[Sidecar Man]

Just fitted some 10 Low Bay Led all wired in steel trunking. Have just noticed my volt stick light up on 3 cables that are not even connected to anything. Gets volt meter out and I've got 38v on it. Seems a hell of a lot. Anyone else found this with LED power supplies

Have you tried testing with an analogue volt meter?

They are great. Just remove the 'test' component inside and the screw driver is really useful.
Right size for choc block, opening small tins of paint, removing screw cover caps, removing battery cover for kids toys.....

its one of those fingerby bobs that tells you are good to go .

if these "dead"cables are running alongside "live" cables, then you will get phantom voltages present. as post #5.earth the buggers preferably at both ends , or remove.
