At home I have (off-grid) 48vdc solar & batteries, grid 208 Wye and 208Y genset. In our second home we have grid 120/240V split phase. (and nothing else so far) PoCo says we are 1.4 miles away from "three phase power" --when I asked what flavor she said "three phase power, sir". Eventually...

I posted a little while back about how best to move an oil tank (with oil in it). When I moved it I noticed a small tray with kitty litter under the bottom shut-off valve. I've been watching it. Looks like it drips maybe one drip every week or so. Maybe one drip every 5-6 days... When I moved it...

Please forgive my ignorance. This is where my lack of NEC knowledge shows. I have 120/240V residential split phase. I'm in the middle of a whole-home rewire (ahj has adopted 2017). I've got a brand new 200 amp square-d panel but not much more than that. I'd like to run a short section of...

Just wondering. I was taught to set tape in durabond then second coat easy sand (90) then maybe a 3rd coat with ES 45 or 20 here and there. Recently been trying Fibafuse tape but same process. I'm happy with it but always interested in what others are doing.

Looks like prior owner notched out the bottom of 15-ish studs to hide the orange oil line in the wall, behind some 3/8" plywood. Plywood is down and I'm hanging drywall. No idea if it is code or not to shove a line like that in the wall but I don't like it (doesn't make me comfortable). I've...

I have a duplex receptacle in 1-gang new work. Tabs are broken off. One receptacle will be on/hot all the time, other will be switched. (switch over bench for extra lighting in back of garage) Do they make duplex receptacles that are two different colors? I Googled and didn't find anything but...

Inside the panel I've been doing it like this picture. I figure it's easy, understandable --and if it's not to code, etc. I can always slide the jacket sections off. For white, yellow and orange jackets I've been using a black Sharpie. For black I've been using a white paint pen. I'm using 3M...

Any other better ideas? It's in a corner and I need to move it so I can finish the insulation and drywall behind it. Could take a few months for the oil to burn down closer to empty and I don't want to wait that long. Thanks.

I got a little carried away with home runs in the house so decided to do a garage-only 100A panel. It is an attached garage, service entrance is in the garage and second panel is going be right next to SE panel. Do I need an additional ground rod for the new panel? Can I come out of the second...

I see a lot of sketchy stuff online --like buy a universal 5-15P at home depot, hook up the ground and plug it into a receptacle... I just ripped out all the old (cloth wrapped non-grounded) wire from this house. I have a ton of solid copper 12 and 14ga. How do I get it from the PVC pipes to a...

As the title says, that's it. Nothing crazy, I need to send the following letter and want to know how to address the building official. He's a cool guy but I want to be respectful. I feel like "Dear Mr. XYZ" isn't good enough. Also is it OK to address fire marshall as "marshall xyz"? Letter...

Looking for a good shade of grey. Probably looking for more of a recommendation of flat vs. eggshell/semi vs. whatever else. Wiring is done, inspector came today and put eyes on for rough and I'm currently hanging drywall. (attached garage, yes I understand firecode/firewall, I'm actually...

I have three NM cables. One #10/2 and two #12/2. 16"OC 2x4 exterior wall. I understand NEC states no ratio of the size of hole compared to the size of the wire. I don't know the rule number but it states something like: "as long as you can pull the wire through the hole without damaging it..."...

Trying to figure out how to use the internet. My copy & paste from a spreadsheet didn't end up looking all that great so here is a link: https://imgur.com/57wrgLw and I also attached the same thing. This seems like an insane number of circuits for 100 amp service in a ~1300sf home. Do they...

I've lurked for a while and finally bit the bullet. I'm having an electrical issue/question in my garage so what better place to ask. I didn't know how to fill out the registration forms. I've got cars, motorcycles and love anything that burns fossil fuels. I can weld (have welders), build...

I have exposed nm-b (romex) tacked to the walls in my garage. Garage has drywall. Looks like someone nailed some 1x8 to the studs over the drywall so there was something to staple the wire to. All the exposed wire is up higher than 8-feet. (my state is nec 2017) I'd like to put in several...
