I was reinstalling a light fixture and it bit me. I measured the voltage from its hot to neutral and it kept oscillating between 0 and 40V . It was not phantom voltage I checked. The light switch (dimmer) feeding this line was off, and there is nothing between the lights and the switch. What could possibly be going on here and is it dangerous?

  • What other equipment was operating in the house or area? only need 1 poor neutral connection...

  • Does the dimmer have a "click" at the end of its range to turn it off, or a separate on-off switch for that matter? Jul 27, 2019 at 15:05
  • @DDS AC. but there was definitely current going through it as per my test with my hand. Jul 27, 2019 at 16:44
