    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...

    I'm looking into replacing about 250 feet of THHN wire thats been buried in PVC conduit for 20ish years. Wanting to do this in order to upsize the wire and make the circuit a higher amperage. I've done the conduit fill calcs and I'm within the limits if I upsize. What is the best way to do...

    Hi there, Is there anything wrong with having 2 220v circuits in the same conduit going in different directions? I have a conduit currently serving a well pump, and I'd like to use the same conduit to run a generator feed up to a main house panel. The conduit is big enough for the additional...

    This is a little long but bear with me: I live on a barrier island where all houses are built on pilings. Most, including mine have the area underneath the house filled in with a concrete pad a few inches thick so it can serve as either a car port or a garage. Mine is one of those where the...

    I added an outlet box and an additional light fixture in my attic. I already know that I should have made the last conduit longer so I could staple it to the rafters <6" from each box. Soon I will relocate it to allow for the staples. Apart from that, is there an NEC issue with mounting...

    For context, I'm working on installing a transfer switch, and re-routing some on-wall conduit to be more in-wall than it was before. This conduit contains 3 #8 THHN wires. This is the red line in the image below. The section in question here is the 90 degree turn below the "future transfer...

    How should conduit (PVC in this particular case) terminate at or above a drywalled ceiling? Specific case is a surface-mounted subpanel in an attached garage. Would it just be a hole in the ceiling drywall, through which the conduit passes and then simply ends with the wire coming out?

    I'm getting ready to install a transfer switch next to my main panel, but in order to install it I need to move some on-wall conduit out of the way. Here's what the space looks like now, with the prior conduit positions shown: And here's what I want it to look like: The conduit will...

    When installing wire in a short section of pvc conduit above ground (like to an outside sub-panel with UF wire) is it permissible to strip the wire's sheathing back the same length as the conduit and then install it? Or is this not advisable since the ground wire would be exposed/unprotected...

    Please send me the link of a coupling or reducer that can join the two conduit types. I could not find them at Homedepot or Lowes.

    I have a security access panel in a closet. Behind the wall is an attic. Through a 1.5in conduit, I have about 3 CAT5e cables running through from the attic through the access panel. Is there a way to seal or terminate the conduit? Right now I just have some masking tape around it, but would...

    Quick question (probably a dumb one) I wanted to add outlets to my unfinished basement. Block walls, open floor joist, with no plans of ever finishing them. I plan on running 12/2 (from the breaker box) through the open floor joist, over to the wall, down a vertical piece of conduit then...

    I'm in the middle of pouring a slab for a new freestanding garage and I'm running 4 wires 100' of #3 AWG THHN/THWN in 2.5" sch 40 from the main to a new sub in the new garage. So far I've run about 30' underground from the new garage and up the side of the single level existing house about 10'...

    Hi, I'm planning several projects over an extended time period which all involve electrical work to various points in my property. An example is i'm getting a new well put in soon; but sometime next year I will be putting in an outbuilding with a subpanel. Even farther out will be a standby...

    Given: There is no requirement for AFCI protection since there is no new work or modifications to circuits. The electrician was working on the main electrical panel, and recommended adding AFCI protection to the bedroom circuit. Since he did not have a combination breaker for this panel, he...

    I have a detached garage ~15ft from my house, which is currently fed by a buried 15A cable. I want to remove that and run the following: - 4x THHN 6AWG (for 50A circuit) - 6x THHN 12AWG (for two 20A circuits) My plan is to dig and run a 2" PVC conduit (18-24" deep) using LB conduit connections...

    For my personal education, please explain the difference in these two MHF cables (mainly the difference in the neutral and ground sizes and why each variation is produced). 2/0-2/0-2/0-1 2/0-2/0-1-4 Under what cirumstances is the larger neutral required? Installing in U/G conduit going 300...

    I am installing a sub panel in my house and running the wire through the attic. I am planning to run THNN wire in PVC conduit or SE cable. Since the circuit will be breaker protected I am thinking SE cable is OK. However if I use PVC conduit and pull the wires I can save some money and of course...

    I am trying to repurpose some existing UF wire. It currently goes through my foundation, with no conduit involved, about 14" below ground and runs a long way to a place that does not need it. I would like to cut it short and bring it up to slightly above ground level to a new outlet that...
