    I working in a commercial building in NYC bad we have a generator (Kohler) with multiple ATS switches in different locations throughout the building. My question is can I run the genset control wires in the same conduit as the Ethernet ( Ethernet is for the ats which goes back to the generator...

    I am working on a service upgrade in Southern California in an area that was electrified in the 1920's w. underground conduit. We dug a nice trench down to an old 2" galvanized conduit to our new pad. When the time came to cut the old conduit we had exposed, to couple on our new conduit, the...

    Hey everyone, New to the forum, but not to DIY. Pretty handy with most things (cars, general carpentry, DIY around the house, etc), but not afraid to ask for help when I need it and for this project wanted to consult some of the experts so I get it right the first time since it'll be a pain to...

    Hello people! First of all, I am not an electrician. Having learned what (relative) little I know about electricity to apply it to a do it yourself off-grid solar system, I have HUGE RESPECT FOR YOU PEOPLE. Lord have mercy, this stuff is confusing!!! LOL. Anyway, I have a question if I...

    I have a question. Typically, when I do a panel change (residential), the cabinet may be lower or higher than the original. Sometimes the cable sheathing doesn't quite make it into the new panel cabinet. Therefore, I would often run metal flex over the cable to protect that portion of...

    I don't have a ton of experience bending EMT. I can make most of my bends without any issues. But I cannot seem to make a 4-point saddle bend in 1" EMT without kinking the last bend. Bending the EMT while it's on the ground isn't an issue. But once I have to flip the bender upside down and bend...

    Hey guys, Just wondering what everyone has done in the past for running conduits in the slab. On a recent job I have completed the layout and also involved in running the actual conduits on site. I have attached a couple pictures for an idea. What have you done in the past for going through...

    I have a friend looking to have a new feed ran to his garage for his future EV in Alberta. He is looking to run PVC underground from his house directly to his garage, and was previously suggested by someone to use 6/3 NMWU. Looking through the code now I'm not sure if it's possible to run NMWU...

    I am wondering people's thoughts on the effect Power over Ethernet will have on electrical infrastructure, especially in lighting. What conduit/cable products will no longer be needed due to this? I assume some armored cabling will no longer be necessary if buildings switch their ceiling...

    Hi All I am installing a 100 amp sub panel in a garage. The feed is coming from the 200 amp main in the house. I will be burying teck cable. The teck cable will come out of the ground at the garage and go straight into the back of the panel. My issue is what is the proper way to go through...

    Hello all :) My name is Kevin, I'm a students from the Cal State University Fullerton. This semester we are working with an independent electrician to create a tool use to bend conduits quickly and accurately. We’re interested in electricians who have experience in residential, commercial, 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 don't use many octagon boxes, but when I do, I mount them to sit flush with the finished wall surface (obviously, i guess). The problem I've had is, using 1.5" deep octagon box and coming into it with 1/2" EMT on the side, the box connector and EMT offset project beyond the stud. This means...

    Hi, I am having serious, serious trouble deciding how I should create a connection where I have between one and three 1/2" exposed run cable going into one side of a gang box and 1" conduit coming out of the other side. An animation (see below for link) I've seen has a box that fits the bill...

    This is not so much a code question, but a practical one. My septic system was installed 10 years ago. The company that did it put a pvc jb inside the effluent tank, in an effort to avoid a post and allow for mowing right over the tank. Sounds good, in theory, but the jb doesn't seal...

    I have come across a situation where I wanted to change where my service wires entered my meter enclosure. I am looking for a reference to find out what is allowable and what might not be. I recently connected an overhead service where I would have liked to punch a hole in the top back portion...

    Im laying out 6" recessed lighting for an apartment. Using remodel cans in old plaster ceilings will be enough of a PITA, but I'm wondering what the best way to run into them. Being remodels, i guess its inevitable that ill need to run some amount of flex. Can I use a flex to EMT fitting at...
  19. NEC Code Forum
    Does the NEC provide any guidance on running flexible cable through electrical conduit? Here it's 12/4 outdoor rated 240VAC cable from an Enphase solar array, and the wire needs mechanical protection between arrays. I'd been told by a local Electrician that the outside sheathing need to be...

    I've run across this a few times where home inspection reports point out that wiring outside needs to be in conduit, the latest report points out two locations. The first is a run along the outside of the house where 10/2 UF is strapped to PVC conduit and runs about 20 ft then into the...
