  1. Electrical
    New homeowner here and weekend DIYer. Changing some light fixtures in my house and in my plastic box there is one hot wire and one neutral, but the bare copper ground wire appears to be screwed to the box. To attach the ground wire from the fixture, should I unscrew this wire that is in the box...

    How to I properly ground this? This gfci is on its own breaker directly from the panel. Can I cut the ground after the green screw in the box and tie all three grounds together with a wire nut? I am a beginner for sure! Thanks!

    I'm about to install a 100 amp subpanel directly next to a main panel to be used as a generator panel during power outages. I'll connect the two with probably a foot of 2" conduit and run the 100A feeders along with the dedicated circuits through that into the sub. I plan to splice extensions...

    Hi, I'm planning to run some EMT conduit sleeves with romex to protect the romex from one wall to another wall. I'm also planning on running some (separate) EMT and metallic raceway for ethernet cables. (NEC does not require the EMT sleeves to be grounded and I am unsure whether the EMT and...

    I'm putting in service wiring for a new heat pump unit and a nearby hot tub enclosure. Two 50 amp circuits plus one 20 amp circuit for a couple outlets by hot tub for lights, stereo, etc. The power is coming from an indoor 200 amp main panel. I am planning a large conduit inside the wall to an...

    I would like to verify some information I was taught today by an experienced electrician. I asked him:"If I have three wires which I don't know which is which -- and the colors of the wires don't help -- how can I identify what's what?" To identify live: which wire lights the tester. Now with...

    I just purchased a re-sale light fixture. When I looked at it, it has what looks like an extension cord but no ground wire. It requires 2-40 watt max lights. There is no smooth / ribbed wire as I've seen before. Should I be ok to connect black and white to the existing wire on the light...

    Well I found out that there isn't a ground wire running from my breaker box to the incoming water supply pipe. This sounds like something I can do myself but I can't find anything online about how exactly to go about this (how to make the bond, type of wire to use, where exactly to connect it...

    Hi, I hope this is a simple question. I am replacing a dimmer switch and when I pulled out the old switch I saw that the ground wire was not connected. There were two ground wires in the back of the box that were connected in a wire nut. When I put in the new switch I would like to ground...

    Hello, I have started a new hobby of refurbishing antique light fixtures. I am currently working with a three-wire, cloth-covered pendant wire (black, white, green), but the new socket (a vintage replica) does not have a place to connect the ECG - at least not one I can identify. So, I need to...

    I was in my attic today doing some work when I noticed a bare twisted copper wire that ran along a ceiling joist. All along it was charred wood and charred fiberglass insulation. Luckily the fire it caused did not sustain itself and I was able to find the problem. I then traced the wire and...

    I hate two-prong outlets. I have one in a box that is cemented in the wall with no access to the type AC (armored cable) feeding it. (It used to be a fireplace.) Among the thousands of threads I have read it was said that one should not depend on the armor as a ground conductor. However NEC 2011...
