As far as I know every splice needs to be accessible. Is there a way to splice a 6/3 cable in the ceiling without having it in a box? I want to run the cable to the garage for an electric vehicle charger but the piece I had turned out short. I have an extra piece but the splice would be in the kitchen ceiling.
What I've seen in other countries is something like a cast resin shell/box in which the wires are spliced and then resin is poured in the shell/box to completely fill it. Do you know of something that can be done in this case which can stay unaccessible in the closed and finished ceiling?
I have 2 light switches in my entry and need to add a 3rd. So…I removed the old 2-space metal box and will be replacing it with a 3-gang old-work box.
The issue I’m anticipating having is: The old knob & tube wires coming in aren't very long. As the locations of the openings for the wires in the 3-gang box is a bit different than the old box, I’m worried that the wires now won’t be long enough to now reach the light switches. So, my questions are... If I need to add 6” or so to some of these wires, is it okay to just splice a new piece of 14-gauge wire onto them?? I simply didn't know if you're allowed to do this. If so, is this just a matter of using a plastic twist cap to connect them…with everything being done inside the new box? Thanks so much for your advice.
I have a grounding question. I am installing 400a service to my new home. We ran 350MCM wire underground thru 3" conduit from the 2ndary terminal (moped) to the house into a 320A Cooper B-Line meter. From the meter we ran 2 sets of 4/0-4/0-2/0 thru the wall to 2-200a breaker panels ("standard practice", according to my electrical supplier). The ground wire (#4Cu bare) from the grounding rods comes up from the ground and we're curious if there has to be a special splice connecting the ground wire to each breaker panel or can we run thru one breaker panel to then next, say by connecting the ground wire to a ground bus on one panel and running that thru to the next with #4Cu bare or #6Cu in conductor. Different electricians are suggesting different methods and the electrical inspector is unsure, but seems to be leaning towards the "special splice". Any feedback would be appreciated.
I am only using a simple "non-contact" voltage detector. I am getting a reading from the switch, along part of the line and then at the lights themselves, but the lights are not coming on. I have not gotten into the attic yet to check the line and junction box. What could cause this? An open connection or loose connection? Any help with troubleshooting would be great.
This is a new install of lights, they were not existing. Power is at the switch. Had single pole now I have a double switch. (the existing light that was on the single pole is still working fine). At one point I connected just the new lights to the existing power, single pole switch, and still did not have lights.
My wife and I are doing some minor kitchen remodeling in a few months (new sink, countertops, backsplash, adding disposal). I was looking at the electric to see what I was in for. There is currently a switch located where you would locate the switch for a disposal... but it shuts off the dishwasher. WHAT? WHY?
So I look into the dishwasher circuit. 20a at the panel, wires run in conduit to the switch location. Out of the switch box comes 14/2 NM-B (WHAT, undersized!) comes out under the drywall and over to the junction box on the dishwasher. So, what do you guys see as the solution here? I was thinking to run a new 20a circuit, with 12 gauge THHN from the panel to the switch box, then splice that to a new piece of 12/2 NM-B to the dishwasher. Question: can the NM-B just lay behind the dishwasher like that? Should it be BX? The 14/2 NM-B would be removed and 12/2 run from the switch to a new outlet under the sink for the disposal. So, I would end up with 2x 20a circuits: one for disposal, one for dishwasher. Does this sound like a solid plan?
This should be simple but . . .
I am replacing a couple old 3 pole switches with 2 new decorator switches. First switch I rewired exactly like the old one black on black pole, a second black on brass pole on the same side, and red on the pole on the other side. I rewired the second switch exactly like the old one was too. White on black pole (I know ) red on the brass pole on the same side, and black on seperate pole on other side. light will turn on and off from first switch but only off from second and will not turn on from first switch if second is turned off. so I rewired second switch with balck on black pole, white on top brass pole, and red on seperate pole. Nothing changed. Do I need to test which wires are actually connecte to each other in the wall or what? thanks for your electrical wisdom
Can anyone please tell me what type of wire i need for my hot water heater? Also is it going to be a double pole 30A breaker or is it just 120V #10/2?
I'm wiring two lights to one switch with power coming into the switch. All the diagrams I see show the connection of the two lights at one of the lights(if that makes sense). Can all of the connections be made at the switch box if theres room? Basically a wire from each light and the power wire all run to the switch box and connected.
I know nothing about car stereos, but I had a crazy thought the other day and figured someone here on this board would know home electrical stuff and also car stereo (electrical) stuff.... so here goes....
How difficult would it be to "rig up" a car stereo (or, actually, an in-dash video player/receiver) in a house, hardwired in? I assume (admittedly, without researching) that the foremost issue is that car power is DC, so the first problem would be getting a transformer to take 110VAC to whatever the stereo required in DC, right? As far as speakers - are car speakers and home speakers essentially the same, as far as the signal sent to them from the receiver/amp/radio? Or are they a different capacity (resistance ohms or something)? Could you use home speakers (say, small in-ceiling type speakers, like you typically see sold for home theater surround usage) with a car stereo? Finally, do these systems typically have standard audio and video inputs in the rear (component, composite, S-video, headphone-jack type plug)? I know they typically have an "aux" input on the front (for video game systems, iPods, MP3 players, and whatnot) but do they have connections on the back where it would be out of view when permanently connected (for connection from the satellite box)? I had this crazy idea that I would love to install one of those car stereos with the slide-out, pop-up TV screen into my bathroom, and have the sound wired to ceiling speakers. If I built a cabinet with a mounting frame that would hold it in place, could this work? I am not looking for some high-end sound system that will blow me away and rock the house, nor do I care about a beautiful HD picture on the TV... I just want to have a small TV and a radio/audio receiver at the vanity area that I could hear with the shower running or whatever, and car systems like this are way less expensive than buying a small LCD TV and a stereo receiver (plus I can't find a receiver small enough). Plus, you would get the added benefit of the TV "disappearing" when not in use. Obviously, this would take some rigging - transformers and all - but can anyone clue me in on the feasibility?
Am doing a bathroom reno and installed a new fan. Original switch was a simple on off single pole. I want to install a DewPoint condensation fan switch that will turn on automatically at a certain moisture level.
The new switch as 4 wires. green ground, red fan, black power, and white neutral. I know the ground, but how do I hook up the neutral and fan to the existing fan set up? There is a double pole light switch in the same box that has a couple wires to it, and there is a mass of whites that I am not sure where they go Can I hook up the neutral somewhere else, or put it with the fan like a single pole? What do I do with this? In the attached picture the switch on the right is the 2 pole light switch and on the left is the fan switch that I hope to replace. Your Advice is appreciated |
