    Wiring a workshop...is it correct?

    "With 225' of #8 AWG copper, you'll only be able to draw about 10A for a 120V load, or 20A for a 240V load, while staying within the guideline of 3% voltage drop." Hmmm....I don't know why I was thinking it would be higher. 10 Amps won't be enough to run my 15 Amp/110V compressor. 20's...

    Wiring a workshop...is it correct?

    I finished the wiring to my shed/workshop this weekend. The connection between the two is 225 feet of direct burial 8/3 cable with ground. Where it exits/enters the house and shed it does so via 2" electrical conduit. The shed panel is mounted to plywood and the electrical coming in stays in...

    Amps at 230' via 8/3

    Thanks for the clear explanation. Much appreciated.

    Amps at 230' via 8/3

    The panel in the shed is existing and it doesn't have a ground rod as it was wired to connect to my generator and everything I found on grounding indicated that when a generator is used the genny itself provides the ground. The feed to the shed from my house is replacing the generator feed...

    Amps at 230' via 8/3

    Does the small panel I have in the shed now not serve as a disconnect given it has a main breaker throw before the individual breaker feeds?

    Amps at 230' via 8/3

    I’ve got a run of 8/3 with ground direct burial cable to run to my work shop that is 230’ away. Using the following voltage drop calculator I get a voltage drop of 3.97% at 15 Amps: https://www.calculator.net/voltage-drop-calculator.html However, I have two hots...does that get me more usable...

    Powering a shed 250' away

    Thanks. If I want 30 Amps and 220V at the shed panel, it looks like to be under 5% voltage drop at around 230' (i can get it down to 230) I need two hot legs of 4 awg. Is it less expensive to run individual conductors or cable? --Rick

    Powering a shed 250' away

    Hi all. I’m looking to power a shed about 250’ feet from my house panel via a buried PVC conduit. Lowes sells Southwire 8/3 Stranded UF Wire with ground by the foot. Is this wire sufficient for PVC conduit burial up to 250’, 2 legs each sending 120V paired to a double throw 30 Amp breaker in...

    Led channels & tile

    Hello all. We're doing a master bath right now and I'd like to put some LEDs running vertically in a waterproof channel to really create a clean and modern aesthetic. I have a couple of questions though... If the aluminum channel is embedded within the tile, is it likely that the grout around...

    Running electrical 250'

    Cable like this qualifies to enter both premises? 1/0,1/0,1/0 & #2 Notre Dame Underground Secondary Distribution Cable

    Running electrical 250'

    I will more accurately measure the distance but it appears that if I'm around 250', using feeder cable I can get at least 2 legs of #2 30 Amp, a #2 neutral and a #4 ground. Does this sound correct? I wanted 50 or 60 amps so I could run a welder but it looks like i would have to go with copper...

    Running electrical 250'

    Hi All. I want to run 30 amps to my work shed about 250 feet from my house panel. It currently has a 60 AMP subpanel that I usually power with a generator. I've got an electric heater in there and some power tools including a wood lathe, saws, bench drill and bench grinders. I believe I can...

    Sharkbite Manifolds...reliable? Pex size recommendation

    Three questions: 1 - I have 3/4 copper for both hot and cold running into the space that will be our master bath. If I sweat on a SharkBite manifold to each of them and then attach Pex to SharkBite fittings, assuming everything is done correctly, will this setup be reliable and not leak 2 or 3...

    Moving a vanity drain about 4 feet

    Wasn't sure I could do that because it's not clear to me what that main stack connects to on the floor below me. So in my drawing it's clearly a vent as it goes up and out to the roof. However, if that stack somewhere below me acts as a drain for the sink or shower in the room below does that...

    Moving a vanity drain about 4 feet

    So if I understand it correctly, my new run should look like the black line I depict in the attached screenshot?

Hey, wait a minute.

This is awkward, but...
