knowing the newer ppl that live in the apartments, they would not say any thing to us if their electricity to part of their place went out for a while. And each of us have our own fuse box in the basement. But the way everything is rigged 'here -there-and everywhere'- It's extremely hard to try to trace back to which box the water heaters are actually connected to! I have tried many times, too many wires and cables going all over. We have even stopped having a land line phone, because we could plainly hear others talking on the phone, through our computer speakers!
