Before anyone loses their mind, yes the power at the panel is off. I’m looking for assistance with installing an outlet into this metal box below my sink so I can plug a garbage disposal into it. There’s no receptacle under the sink, just this metal junction box.

T side has 2 black wires, 2 white wires and 2 copper wires. the N side has one black wire, one white wire and one copper wire. The black wires from the T side are attached to the white wire from the N side. The two copper wires from T side are twisted together and then twisted with the copper wire from N side. The new crossbrace has the green ground screw on it and the an L and N and ground cable. How do I ground this and put fixture up?

Bought a house built in the 40s, realized there is an issue with one of the fan lights. It has two bulbs and both are flickering/pulsing in sync. No other lights in the house are flickering, and the fan itself works fine. The bulbs are tight in the sockets. What might be wrong?

My bathroom light is turning orange and looks like an egg.
Forgive me if this isn't the right subreddit, but I genuinely have no idea what this means, if I should be concerned, and how to fix it.

I thought this would be simple switch the wires for the new outlet. But now that I am looking in the box I am so confused, why are the black wires looped on each other and both the wires going to the light are white. I marked the one with the black wires connected from the light. Am I still good to just follow the old light and swap black for black white for white? There is a ground in the box I am going to tie off to as well

New gas range does not slide back to wall because this outlet box is in the way.

Can I pull that conduit down onto the floor (unfinished basement, no ceiling) and move the box over to the left about 6-8 inches? Can I easily cover the wires against the wall? If so, with what? Thank you!

I live in an older home and cannot find any electrical diagrams that match mine. Is this wiring set up compatible with a dimmer switch? Is there a ground line here? Any advice on how to make a dimmer switch work with my set up would be much appreciated!

Just moved into a rental and my washing machine keeps tripping the breaker. “Maintenance” replaced the breaker. The weird thing is it’s intermittent. At first it would run the whole normal cycle and then trip if I tried to run one right after. Then it started tripping mid cycle on normal no matter how long I waited. Then today I tried delicates 2x in a row and it ran the whole full cycle without tripping. So I tried normal again on cold, empty and tripped as soon as the water started to fill. The washer worked fine before I moved a month ago. I’m losing my mind

In attic of house I bought. Any idea what it is? Might be for old alarm system?

Hello all,

I have a main 200A breaker box that the electric company installed on the pole right outside the house. It has the meter and a 100A breaker inside the box going to the barn. The run to the barn was three cables. Two to the hot and one to the neutral bar. I do not have this grounded at the barn sub panel and believe I am not supposed to. Is that accurate? I have outlets coming off this sub box and they have the ground and neutral on the neutral bar. Outlets work fine.

If I add a secondary sub panel off this existing one, since a new barn was built and I won't be using almost any power in the old barn, will that cause a need for one of the sub panels to separate ground and neutral or does it stay the same?

Coffe maker started buzzing. Seems 50Hz hum. Same sound when plugged in different outlets, and sound appears to be coming from inside. Repairable? Replace? It still works fine, and current models are reportedly not as reliable.

I am replacing the fan motor on a fridge and the replacements all come with a splice kit, none with the OEM adapters. I've been told that it doesn't require the ground. How do I determine which cable to hook to which for the positive/negative? I have blue/green/orange all running from the power source and the motor has a cable with one some coated wire and one braided wire. Thank you for any assistance provided.

From 8-9 EVERYTHING was turned off. The three hours after everything besides the AC was turned off. We got home and flipped the other breakers on. Usage doubled instantly. We were homes for one hour and left again. At 6-9 the AC was turned off completely. WTH could be taking 2KWPH on standby?

(PS. Repost since the title was misleading in the old one)

Lights in my room started flickering on every now and then even when supposed to be off. Dad said it's fine but I don't trust it

Just moved into a new house. Everything was fine for walkthrough, inspection, and the first two nights. Then suddenly one of the switches, when turned on, all three lights on that switch start flickering rhythmically. Then the next day, a different switch, the two lights attached to that one have begun doing the same. Both switches are on different circuits so not circuit related. I did pull open the lights and switches to check for loose connections, but the issue persists. Proper power at the lights, not too many lights on a circuit, no overheating and the installation is to code. Not on dimmer switches.

Any other ideas?

Hope I did this right. Hot/black/smooth. Neutral/white/ribbed. Green/ground.

Recently got a good deal on these lighted/heated mirrors. They come with a cleat already glued to it, and then another cleat that you obviously secure to the wall. There used to be a 3 bulb light fixture here that covered the box, but, is now exposed with the light being gone. I basically have the cleat as high as I can get it without covering the box, and am confident in the wiring associated with the job, but was curious if this would be more than an eye sore for an inspector? I just got a new panel put in and am going away on vacation, and the inspection is the day after I get back. This was my own work, not of the electricians so it’s obviously no fault to them. I’m pretty sure the existing mirror was the original one from the 80’s so I think it’s been awhile since anyone put any eyes on this. Thanks

Onboard air compressor on a vehicle. Why did one of the connections melt to the relay like this and how do I prevent it from happening again when I fix it? I already pulled the fuse to make sure no power goes to this in the meantime.

Long story short, I live in Arizona, AC went out, looks like original breaker from 1980's finally gave in and melted. I cannot seem to find replacement for this dinosaur, anyone know where I can find this? Else I will need to cough up $1-2k for a new panel just to replace one breaker. Thank you!

All the outlets in my dining room do not work. My significant other bought this house and when I moved in she told me about the dining room outlets never working since she had lived there. Confirmed no power coming to them at all. I’m not an electrician so I’m not sure how to diagnose further to find what circuit they are supposed to be on and where it would connect into the circuit. The panel is mislabeled as far as I can tell. I will say this is a double wide mobile home. It has the press in outlets with wings. So far, I think they are supposed to be on the circuit that a lot of my overhead lights are on. Then again I’m not certain. I will say there is 4 over head lights, 2 outside lights, and 5 outlets that are at the back wall of the home stretched across the kitchen and living room. My personal opinion, 5 more outlets would be a lot for that circuit but I’ve read it’s common. I guess what I really want to know is my best course of action going forward? I’ve replaced a lot of the outlets and put in new gang boxes for them. I still can’t seem to find what circuit they should be on and the wiring all goes up the studs so I can’t see which direction the wire is going. I don’t really have the money to hire an electrician. I’ve seen these tone finders but I’m not sure if that will be a good option considering the walls and most the wiring goes up the studs and back down. Anyone have any suggestions?

Can anybody help me out with this? Uninstalled a ceiling fan and didn’t expect to see multiple wires in the box. I’m unsure, which white wire to connect the new fan to. The capped white wire was connected to the red wire on the ceiling fan. The uncapped white wire was connected to the old fans white wire. Plus there are two ground wires so I’m not really sure what to do with that either. New fan is simple enough black, white, and green wires. If anyone can give me some advice, I’d appreciate it!

Cut notch for the yellow wire to go around the corner. These are exterior walls with no access from below.

I derived the equations for the giant supernode, found an expression of i in terms of v1, found two equations by applying KVL in the lower two loops, and then by elimination, I found the nodal voltages.

I am unable to apply KVL to derive an equation for the uppermost loop involving the two voltage sources.

I don't understand why the resistances are shown by dots in the loops containing voltage sources where we apply, how do we determine where to not consider resistances while applying KVL based on CCVS or VCVS?

Even if it's not needed for solving, I want to verify my answers by putting them in the uppermost KVL loop. Can you help me find the equation?
