Do I need to replace 14-Gauge Wire on 20-Amp Circuit?

Except when there is an actual danger right now (there isn't), the problem is always the future. It is extremely unlikely that any future homeowner or electrician doing additional work will notice the ...

Should I rewire my house?

the electrical system as a whole is grounded via the conduit with no ground wire present That is perfectly fine. As long as it is all metal conduit (conduit can also be PVC) and connects to metal ...

How do I install a smart switch with this wiring I don't understand?

What you are likely seeing is "phantom voltage" except when the circuit is turned on. That is quite common and doesn't necessarily mean much. The key is "120v (0v at switch) when ...

Is this a sound plan for rewiring a 1920s house?

How will a stud finder find the wires? Usually, there is no bonafide way to identify a buried wire's run except by trial and error. This is why after virtually every knob-and-tube removal, there are ...

Electrical line has no juice after being shortened

Usually there is a switch before the disposal. You push a button, or flip a switch to turn on the disposal. Did you turn the switch on? If this is the case, then this was not the best option for this ...

Can I get 240v out of a 120v generator?

What you describe won't work, and it's not safe for you (or anyone else) to do what you describe. If you have a single phase 120 volt generator and you need to supply power to a 240 volt split phase ...

How to repair basic cable/wire issue for household appliances

There's no good way to repair just that wire, and the adjacent wires are also probably close to failure. You'll need to remove a section of cable and rebuild. Label the cable a ways from this end so ...

Wiring an in-line on/off toggle switch on an LED lamp with additional controllers is not working as expected

Yeah, this is a "throw parts at the problem and hook stuff up randomly" type deal. There is a significant knowledge gap here. Not least you did not notice the circuit is on with the ...

Do I need to replace 14-Gauge Wire on 20-Amp Circuit?

In the real world you can't control what crazy-seeming thing the next guy is going to do 20 years down the line. What seems unlikely to you today (extending the circuit off the end of that 14 gauge ...

Stapling cable inside of a box when there is no room

Is it safe to replace a lamp's UK 5 amp round 3 pin plug with a 13 amp rectangular 3 pin plug?

Yes - almost certainly. You need to get the wiring right (the wires should be colour coded in the usual way - if in doubt post pictures). The pins are in the same positions in both plugs. The 13A ...

Wiring question regarding replacing hardwired fluorescent shop lights with LED plug-in lights

For what it's worth, my solution was to install outlets in the ceiling box, using a faceplate designed for the purpose, then just plug in.

Can I get 240v out of a 120v generator?

Transformers are your friend! Easy peasy, if the numbers work. Start by looking at the air conditioner. You need to know the number of "watts" the air conditioner uses, probably between 1000 and ...

Can I split a circuit in the middle of a 3-wire cable?

You can splice into a 3-wire cable just as you'd splice a 2-wire cable, assuming it's not for a three-way switch or some other specialty case. Do it as you've drawn. You'll need slack. If you don't ...

You're better off re-routing the feeder to the new box, and then running power to the original box as a subpanel. The reason is subfeed lugs are costly or unavailable. The only panels that come with ...
