A few years ago, I had my kitchen renovated. This included replacing
the old overhead light (regular bulbs) with halogen lights (the
dangling kind). Everything worked well.
Recently, I've noticed something really bizarre. When I turn on the
halogen lights, one of the GFC interrupters trips. The GFC outlet is a
few feet to the left of the light switch.
The bizarre part is that the GFC outlet is on a completely different
circuit than the halogen lights. Yes, I've tested this with the
If I turn the light on, reset the GFC, and then turn the light off and
on quickly (1-2 second delay), the circuit doesn't trip. If I wait
longer, it trips. The transformer for the halogen obviously needs a
second or so to "power up", so this is a clue.
There are two switches for this light, on either side of the kitchen.
Both switches cause the GFC outlet to trip, so it's not the switch.
Just to make sure, I checked the switch that's closest to the outlet,
and the wiring looked OK (although for some reason, it is a 4-way
switch, despite the fact that there are only two switches for the
The only thing I can think of is that the wires from both circuits run
side by side in the ceiling, and the transformer is somehow generating
a field that causes the GFC outlet to trip. Is this in the same
category as aliens-have-infestated-my-house or is this at least a
remotely plausible explanation?
I could test this theory by wiring a regular light instead of the
halogen light, and see if it still trips. Before I climb onto the
countertop, I'd like to make sure I'm going in the right direction.
Any advice greatly appreciated.
