Hello friends Replaced a smaller window ac with a larger one altho both were still 110s. problem is that sometimes the ac will trip the breaker, it is in the bathroom window and the breaker supplies both bathrooms electricity. don't recall the other unit tripping the breaker. House is about 25 years old and the breaker is a "American" brand? have a tough time finding replacements. Do u think that the breaker is just old and should replace with same size or should replace with a larger breaker, currently is 20 amp. In the fall i want to replace the whole breaker box with a updated version.

Hello, I have an older home, and 2 3-way switches (top and bottom of stairs), which control 2 lights simultaneously. Wiring is BX for these switches/lights, and I'm not sure what the order of wiring is for this setup. Wiring is old, and hard to even tell black from white. Here is my problem: The switch at the top of the stairs was an illuminated 3-way, which worked just fine. Switch at the bottom was a normal 3-way. I replaced BOTH switches, putting a NEW illuminated 3 way back at the top of the stairs. I tried to hook them up exactly as they were removed. Now, either switch will successfully turn on/off both lights, as before, but the 3 way illumiated switch has a couple problems. 1) The 'illuminated light' on the 3-way switch is always on. This should only be on when the lights are off, as it was before I updated my switches. 2) The illuminated 3-way, if you 'tap' it just right, or don't hit it 'gently' enough, it will 'spark' or 'pop' and trip the circuit. I have tried a new illuminated 3-way switch, as well as hooking up the 3 wires going to that switch in every possible combination. I cannot seem to fix either problem. I would assume that since the 3-way functionality is working properly from both switches, that the wiring must be correct - but something must be wrong. Could the problem be with the wiring of the OTHER 3-way switch at the bottom of the stairs? Would that have any effect on the illumination at the top of the stairs switch? Any help or advice would be appreciated! Thank you.
