To clarify: Yes, an extension cord can heat up in normal use, meaning plugged into an outlet with an operating appliance on the other end. Yes, a coiled cord will heat up faster, because the heat is concentrated in a smaller space. No, a cord plugged into itself does not contain endlessly circling electricity; that is called a perpetual motion machine and is a violation of physics.

Think about it for a second. The heat emitted by a cord under load comes from electrical resistance. So we know the cord has resistance; therefore electricity cannot circle endlessly in it. The resistance dissipates it. Also, since electricity is the movement of electrons between negative and positive charges, then even if there weren't resistance, the flow would stop once the charges had all evened out and the entire cord was at the same electrical potential.

Also, it wasn't mentioned, but a cord that is plugged in on one end but has nothing connected on the other end will not heat up. There's no current flow, hence no energy passing through the cord to be dissipated as heat. The cord has to be part of an active circuit for it to get hot.

. . .a cord that is plugged in on one end but has nothing connected on the other end will not heat up.
Right.

But just to be a little fussy, unless it has a short.

I only bring this up because I see a lot of extension cords strung up, wrapped around studs or joists, left on the floor or the ground, etc., when not in use, and exposed to damage. Sort of like 'permanent - temporary' wiring. These cord are often kicked around, or run over, and have damaged ends or insulation, and can short if left plugged in (they usually are). If the short is not large enough to trip the fuse/breaker, and there is flammable material nearby, it can lead to a hot time in the old town that night.

Right.

Fire inspector showed me after a house fire. Couple had run some extension cords for power, and a mattress on the floor for a bed. Lifted up the mattress and you could see the burnt imprint of the coiled cord, and how the fire progressed through the house.

Even if not insulated like that, the coils do not let the heat escape. I had friend wiring a new house and the electrical inspector made him re-do some of the Romex (NM cable) between the studs, spacing it farther apart, for the same reason. Doesn't have to happen a lot, but enough that it is a concern.

Yeah, generally only x amount of wires per hole and conduit.

It may not heat up much but there is still a little bit of current flowing in the coil due to induction effects of alternating current.

Here's the opposite of a craigslist laugh. I hired a painter from a CL ad to paint a bathroom that was all fiddly cut-ins; I just didn't want to deal with it.

I should have known things weren't going to turn out well when she showed up with her tools in a plastic garbage bag and said "Oh good, you have a ladder." I was outside splitting firewood for most of the time she was working, and only got an inkling of what was happening when my wife went in to check on her, came back and told me, "She's doing a really sloppy job." My standards for job quality are quite a bit higher than my wife's are - the words "anal" and "picky" have seen regular use - and if she said it was bad, I knew it was going to be bad.

The "painter" struggled for six hours, getting as much paint on herself as on the walls, and what I received was a paint job in about a dozen randomly-distributed shades of brown. She apparently never stirred the paint at any time over those six hours, and the pigments settled, and so every time she'd pour into her tray she was rolling a different color. This would have been bad on its own, but she made it a lot worse by periodically going back and doing a roll or two on a wall she'd painted earlier because she saw something she didn't like, so there were random strips and patches of color all over the place.

The cut-ins were sloppy and haphazard. There was paint on the sink, the toilet, the tub, the shower, the mirrors, and the ceiling - but amazingly there were places where she'd missed the wall. She claimed she'd put on three coats, but she'd only used one gallon, so I think not. When called out on the uneven results, she blamed the paint. (She had been pushing Behr, but I'd already bought Sherwin-Williams.)

I should have known better. You pay cheap, you get cheap. I wound up taking the whole day off from work today to fix it. Taped straight lines to cover all the wavering cut-ins and repainted the entire room properly. It looks nice now, but I had to put in more effort to fix it than if I'd just painted it myself in the first place. Live and learn.

these are the smallest logs I've ever seen.
Free wood for your fire

I am trying to get rid of twigs and logs from a tree that fell in our backyard during the ice storm. Worked on it over the weekend and placed it *neatly* on the curbside. All the twigs are bundled so it can be hauled away - could weigh about 50-60 lbs. And I DON"T KNOW WHAT TYPE OF TREE IT WAS. If interested, pls come and get it. Obviously, it is free. I will take down this post once it is gone. Location shown in map. If unsure, pls reach out.
