I am having a problem with my Semens 35 amp GFI. When I use

I am having a problem with my Semens 35 amp GFI. When I use a regular Semens 20 amp braker everything works as advertised. When I use the GFI any thing I use trips the braker even a garage door motor that is not running.I ran a # 10 stranded wire to connect to # 12 solid bx cable for outlets, lights and 2 garage door openers.I disconnected each junction box. When I turn on any light switch on or use an outlet it trips. With every thing connected, as soon as I turn the garage door opener on ( not energizing the motor ) it trips too. ?????

My hard wired dishwasher had a "cord" problem - there was a

My hard wired dishwasher had a "cord" problem - there was a recall on it and I'm replacing it with a proper plug in style cord. My issue is that that the old electrical wire is in the floor - with no way to really wire it to a wall outlet and pretty difficult in general to remove it all together. My thought was to wire it to a floor outlet. My concern is the floor outlet is directly below the dishwasher. It will not be used as I have an under sink outlet I can plug the new cord into. Dishwasher has never leaked, I can put some type of cover over the outlet once it's wired - but just am uncertain whether this is kosher or not. Any thoughts?

I have a strange electrical problem with a house built in

I have a strange electrical problem with a house built in 1980. While replacing some receptacles, I noticed that when I turned off the breaker and removed the wires from the old receptacle, it became "hot", and all of the LED lights in two rooms started blinking in a random pattern. I had to turn off two breakers to safely replace the receptacle. The break-away tab by the screw terminals was not clipped, which would normally be the case when one wants to isolate a duplex receptacle from another circuit. Now, the two breakers I had to turn off were on the same right side of the panel, so I would assume they're on the same phase. What gives?

I have an outlet that is reading 120v from hot to ground,

I have an outlet that is reading 120v from hot to ground, from neutral to ground and from hot to neutral...120v at all three..what does this indicate?JA: I'll do all I can to help. How long have you been dealing with this?Customer: Standard three prong, two plug outlet..top plug reading normal, but bottom plug reading as I already statedJA: Do you plan on doing the work yourself?Customer: Was moving my dryer to check my vent line three winters ago and the entire house surged and went dark. I lost all of my TVs, phones, toaster, radios, etc that were plugged in at the time, as well as my furnace. Since that time I had partial power come and go in odd places..one outlet in each room, some room lights but not all..I located a short in one of my outlets due to black burn up the wall and removed the outlet, capped the lines and since the intermittent lighting had ceased. I recently began to assess my furnace and found that the transformer was bad. Replaced it and when I applied power it immediately began to overheat the new transformer. Also verified that my blower motor windings have shorted and I need to replace the motor. I'm afraid to complete the repair due to past power issues without troubleshooting everything, so I started by checking the power at each outlet. That's when I came across the before mentioned issue. Yes I hope to resolve the issue myselfJA: Did you check the furnace's filters?Customer: Yes, but what does that have to do with the 120 at the outlet in another roomJA: Anything else we should know to help you best?Customer: Is this a real person or are these answers computer generated. I just gave a valid description of the issues

Two issues here and questions regarding them. First, 1)

Hello,Two issues here and questions regarding them.First,1) Grounding issue detected through tester in the outlet.2) I have checked the outlets on the affected circuit as well as switch ground and ceiling fan. All connected to each other through ground.3) Went down to panel and open the panel cover. Identified circuit and checked connection to panel ground up until exposed ground exists the panel. It is connected.4) Checked from affected outlet box ground to bare/exposed ground in the panel and connection is 'open'.5) So ground of the circuit somewhere is not connecting......Any ideas what is happening and how to find out where the open ground is?? Wire is not exposed and is behind the wall.Second,1) On the same circuit as above (important), I turned on circuit breaker at the panel and contact-less tester does not detect live wire. When I turned off everything on the panel and ONLY turned on problem circuit and brought contact less tester (Kelvine tester) on the black wire - where wire enters the panel - I see live wire. But as soon as I go test where wire exists the panel with jacket (Romex) I do not see live wire detected by the tester. Totally confused as to why no live wire detection in the panel and no detection as soon as wire exists the panel..... I verified another wire that exists from the same connector as circuit in question and turn on/off and tester just works fine on it and detects live when it should....but not on the circuit that is having grounding issue.This is older house and wiring is done in 1970's sometimes.

Wiring in my new hvac compressor. It is a 13 seer, 2.5 ton

Wiring in my new hvac compressor. It is a 13 seer, 2.5 ton unit. They say it needs a 25 amp circuit. I bought a 30 amp fused disconnect box that I'll mount to the outside of my house near the compressor. I'm using 10/2 exterior wire with a ground. The wire is about 1/2 " wide. What type of conduit do I need to use between the disconnect box and the unit? Do I need to use water tight, or just the flex type. I live in Minnesota.

This AM we turned on the hall light and the hall light came

Hi,This AM we turned on the hall light and the hall light came on but also the bathroom fan. This is definitely not normal but both are on the same breaker.I turned off the breaker.How can I find the problem?I looked in the attic and did not see any problems there. Just a visual inspection of what I could see but much of the house wire is under insulation.I looked in the switch for the bathroom fan. A 3 switch configuration in a one gang switch box and all looks right there as well.Any suggestions?Thank youNeil C.
