A bit of an oddball question. We bought, through a US distributor, a ceiling light fixture that was made in Europe (Netherlands). It is a metal fixture, connected to the ceiling via a metal chain, which connects to mounting bracket which has a grounding wire attached to it at the bracket only. The lamp wire is 2 wires, one with blue sheathing, one with brown sheathing. The bulbs are E14 which I connected with an e14 to 12 reducer. I checked on EU standards and blue wires are neutral, brown is for line. When I wired it, it did not work but it was not hung at the time (I was testing it). It was sitting on cardboard box that was on the floor. A non-contact tester lit up when near the fixture (all over it) when the switch was on. I immediately disconnected it (after turning off the breaker). This is a well made fixture from a reputable company, wires appear intact, no obvious reason to think there is some kind of a short. It did not trip the breaker when hooked up.
My questions are 1) Using a multimeter, how could I test the fixture if re-wired to ensure that it is not actually live (maybe the non-contact tester is measuring a floating ground?)?
2) Is it possible that a fixture will not work without being connected to the "ground?" I have had that happen with a step down transformer which would not work until the ground wire was hooked up. No idea how or why that was that way (if someone knows please let me know).
Thank you very much for your help.
Lastly, I am contacting the seller to find out if this is approved for sale in the US. The company website does list the US as an area of distribution. I think they also make some of the fixtures for a large US light seller so I'm pretty sure it's ok. Thank you again.
