RVelectricity Weekly Digest 7/7/24
mr mike. this happened to me yesterday and while it did not occur in a rv it may still apply. the ballast went out on the fluorescent lights in the kitchen. it turns out it is more expensive to buy a replacement ballast than it is to buy an entire new led fixture. so i made sure the existing lights were off and started to remove the existing fluorescent fixture. in doing so i got a shock from the black (hot) power lead. but i had made sure the lights were off! in thinking about this i realized that there are different ways to wire a switch into a light circuit so that the switch turns the light off. power may be fed directly to the light fixture and the switch opens and closes the neutral. the light will go off but the light fixture is still powered. moral to the story: use a non-contact voltage tester and verify that the power is actually cut, not just that the circuit is opened. turn off the circuit breaker if necessary.
