What is the red switch plate at the top of my basement stairs for?
Vo-tech student, electrical, Passaic County class of '27. This is about my grandparents' house in Wayne, which I've been looking at much more carefully since I started the program. At the top of the basement stairs there's a switch with a red plate that says something like "burner emergency." My grandfather says it's for the oil burner. They converted to gas a few years ago and the boiler is new. Does that switch still do anything now? Is it supposed to stay with a gas boiler, and if so, why is it at the top of the stairs and not next to the boiler? I'm only asking out of curiosity, I'm not planning to touch it.
