Exchanging circuit breakers?
Comments (6)Normel: Thanks for replying--I understand where you're coming from. I guess it still isn't too clear to me what the OP means by "hooked up with a 20a breaker on the left side and a 20a breaker on the right side". I don't know whether that means the breakers are on the same pole, exactly to the left and right of each other on opposite sides of the panel. My preference for MW cc's (and code now, I believe, in those jurisdictions using new NEC version) is to use two-pole breakers or, at least, to use handle ties. That more or less ensures the breakers are not on the same pole and also means the neutral won't be carrying current when one but not both of the breakers are turned off. But it's an issue that's come up before in this forum and there are at least a few sparkies here who argue that sometimes a feller's gotta put the breakers where slots permit, so long as he's sure they're not on the same pole. I think this OP's probably gone now, but I did want to raise the possibility that the overall wiring may be OK, but there's another garden-variety reason a breaker is tripping now and then. It seems to me that's at least as likely as concluding an electrician totally bungled the job. And while I agree that a miswired multiwire circuit can lead to an overloaded neutral, that's not likely to be the cause of the intermittant breaker tripping, given the infor provided in the post. I dunno. YMMV. Thanks again and cheers, Tom...See MoreCircuit Breaker Tripping
Comments (12)You can check inside the fixtures, and at junction boxes you have access to. these are often common places for failures to occur. An actual failure in the branch circuit cables is not as common, but if there is a weak spot in old insulation even a nearby lightning strike can produce enough further damage to trip a breaker (and ruin a section of cable by producing a permanently damaged spot in the insulation). We used to use 'meggers' (mega volt meters) to produce high voltage to trouble shoot these types of problems, but most modern digital meters in resistance mode on a turned off and disconnected circuit are more than adequate for checking insulation for weak spot.

Comments (12)We put our house on the market after we moved out. Frequently there would be lights left on after showings. If my realtor had an open usually everything would be turned off. If it was some other realtor doing a showing things were left on. I can't imagine how my realtor would control those people though I could have asked him to go over there after every showing and turn the lights off. Since the house wasn't that far away I ended up going over there any day there was a showing to make sure the lights were off. I was still going through some stuff and moving small things so it wasn't a total waste of time. Fortunately the place sold in about three weeks so I didn't have to do this for long. It happens all the time. I see homes for sale that I know are not occupied and the outside lights are left on for days. However I wouldn't turn the breakers off and on. If you can't get a realtor to turn the lights off I can't imagine they'd be able to handle that. I did make sure my water was turned off however and it was left off....See MoreVacuum Cleaner Tripping ACFI Circuit Breaker on Certain Outlets
Comments (22)@BTThere's actually two sub-panels. The original sub-panel was an Eaton type CH panel (see above screen shots at beginning of post). The second panel is a Schneider/Square D Homeline (HOM) panel. My gut tells me they put too much on one circuit breaker. The circuit breaker indicated this with the blinks. The issue is how do you fix it without tearing into a wall? Most of the main level of the house was taken down to the studs. They ran all new wire except for the two extra bedrooms and bathroom. This is a 15 a circuit breaker. When I asked about upping it to a 20a, the electrician said it was not possible due to the existing wiring in the two bedrooms. I believe they have on the 15 amp circuit - 2 bedrooms, 1 bathroom, living room outlet where router and tv is, hallway with smoke detector, kitchen cabinet lighting, and second smoke detector. I found out about kitchen cabinet lights when the breaker was first tripped by the contractor while adding a dimmer to a kitchen cabinet. Perhaps this is where your theory comes into play that when they added new wire, they split it into the existing wire?? During their second attempt to fix, they did find an issue in the under kitchen cabinet light. I think it was the ground fault issue. Unfortunately when they tested the fix (per hubbie), they had unplugged everything and then ran vacuum. The vacuum did not trip it but lights flickered. Today we had router going, two computer, and room lights. I flipped the switch on the floor space heater (which I've used before without issues) and it tripped the breaker. Then after resetting the breaker I turned heater on and no issues. The vacuum though tripped it every time I turned it on. The contractor and electrician are coming tomorrow at 7:30 and I'm dreading it because I know I'm going to have to fight with them to do it right. I know that I'm all done with this sloppy work....See More- 11 months ago
