My thought was to share it with the lights, so you get an early indication if/when there is a fault than just your fridge going out.

Didn’t notice the coffee was cold?

Overall, given the massive fears of a fridge failure, which can happen beyond just electrical failures, very very very few people have any kind of monitoring/alarming for this event. You’d think that would be the first requirement.

> counter circuits were shared with the refrigerator

Ouch. Code here (Ontario) is that not only does the fridge need a separate circuit, but counter outlets need two separate circuits: each socket on the duplex outlet is required to be on a separate circuit (although multiple outlets can all share the same two circuits, but you're supposed to alternate top and bottom).

Of course, if your home is older than I am or it's a handyman special, all bets are off. If I run the microwave while someone is vacuuming in another part of the house it'll trip the breaker.

Good point. I haven’t tripped a GFCI in a long while but I don’t actually know if my fridge will lose power when I do trip the GFCI. My guess is that it will since it does have a water line and ice dispenser so probably requires being wired into the same circuit.
