I got a 240 plug in room a, running 4 1000 watt lights.
I got a table lamp in a 110 in room b
When the 240 kicks on in room a, the light i have pluged into the 110 goes off for a second or 2 in room B, actually the rest of the house, then they're back on, without any breakers tripping. These are obviously different circuts, why is this happening, and is it dangerous?
