Build an inexpensive and yet effective inter-communication system at home or office with ease! Plugs into a 240V power point and will send to another room, upstairs etc., ...Price: $29.98

Does anyone know if this would work if the plugs are on different circuits? If the circuits are both single phase, but if one trips, the other one doesn't, so they're on different circuits, would this intercom still work? Sort of obvious, but worth double-checking. Ta Jason

my understanding is, it will only work if they are on the same circuit, in fact, same phase....so my guess is, if the circuits are on different circuits (not sure if this sentence make sense or not), even if they are both single phase, it probably won't work.

Even room to room the circuit varies, so mine are in the cupboard, and have been after the day I bought them.
