I have a 50’ (15.25 m) extension electrical cord on a wind-up reel.
It has a separate 10’ (3m) cord from the reel hub, to plug into the wall outlet.All I want is a way to plug it into the wall and be able to unreel it as I work, without that 10’ section getting all twisted. Kind of like a phone cord detangler (pic below), or the brake cable detangler/gyro on BMX stunt bikes.
I was trying to think of a way to make one but apparently it’s a “dangerous fire hazard” or whatever.

I've heard the Christmas lights one before too, but I never got it. How do (American) Christmas lights work that you'd need one of these cords?
In North America, Christmas lights usually have a plug end and a socket end so you can connect multiple strings together in series.
If you accidentally put the plug end at the top of the tree, it might be tempting to try to buy or make one of these cords so you don't have to take the lights down and redo them.
It is as dumb and lazy as it sounds.

yeah, that's some counter-productive signage.
like getting on a bus and seeing:

It is written in the book of Leviticus: "It shall be unclean for one end of an electric cord to match the other"
Holy shit, this is what that part in the bible is actually about. People back then just didn't know about electricity so they thought it was about gay people.

People use them to make their generators power their homes, by adding power into an outlet.
So, whatever time of year power outages are likely to happen in this area.

I have heard there are ways to use these to back feed power from a generator into a house’s system, at least on one breaker, but by definition that bypasses the breaker panel, and the only safe way to use your generator for your house is with a proper cutover installed by an electrician. I can think of literally no other use for one of these cords, except maybe fixing your fuck up if you install Christmas lights backwards.
So yeah, dumb, dumb idea.
There are voltage converters (230V<->120V) that have female connectors in both ends. So if DIY guys are playing with tech from other continents.

I'm gonna guess winter, hanging Christmas lights. People string up their lights and then realize far too late that they put two strands with female ends facing each other and instead of restringing they look for a male-to-male cord to bridge the gap.
A little live wire shouldn't stand in the way of holiday cheer, after all.

honestly tho. if the Torah is legit its advice should apply to the future too. haShem wouldn't just have been writing to Moishe's time.

Holy shit, does that work?
I'm only familiar with having a generator properly wired into the house system at the panel, not some electrical Uno Reverse.

Any serious DIY person can just splice an extra male plug onto a cord faster than driving to the store and reading this sign.

I don't understand why it would have female on both ends?

My friend's house does this with their generator. There is a lockout on the breaker, and the main must be off to move it and open the one that feeds the back porch where they tie the generator in. Once the breakers are cycled, they can plug the generator into the outlet on the porch, and it runs there, sheltered from the weather. When the main power is working again, they turn off the generator, remove the cord, disable the breaker, toggle the lockout bar, and turn the main back on. The particular outlet on the porch is useless when using grid power because of this setup.
So if it's only for the generator, why is it wired as an outlet, not an inlet?

If you have to ask, don't do it.
The proper way to connect a generator is with a breaker panel interlock. This gives you a circuit breaker for the main, grid power; a second breaker for the generator; and an interlock device that only allows one of those two breakers to be active at any given time.
Trying to use a suicide cable can get power into the house; disconnecting the main breaker would prevent the generator from back feeding the grid. However, the circuit you are plugging the breaker into is only rated to 15 or 20 amps, and you're backfeeding it with a lot more. You can easily overload this circuit without actually blowing a breaker.
There's other problems as well: your house wiring is designed for two opposing hot, 110v phases. These are combined to provide 220v power to major appliances. Improperly backfeeding your wiring can potentially damage those major appliances.
You are better off with a nice, heavy-duty extension cord than a half-assed suicide cable.

wrote on last edited by [email protected]It does, but it's super dangerous to do unless you have it wired up properly. Proper installations will use a special connector so you can't plug anything else into that receptical, and will have it interlocked against the main breaker - you can't plug anything in without disconnecting from the grid. The dangers of doing it amateur-hour are:
- You now have a cable that you can unplug and have live ends exposed - which if you don't realize is connected to an active generator is super dangerous, and even if you do one slip and you are now the ground conductor
- If you connect the generator while still connected to the grid, your generator is almost certainly going to be out of phase. This will probably cause damage to your generator and anything else plugged in at the time
- If you don't have an interlock and run the generator while connected to the grid (say during a power outage) you will be back-feeding power into the grid. This is super dangerous for anyone coming to fix the outage, as things that they've isolated to fix can still end up being live
Note that this interlock is also required if you have solar - although it's usually in the form of an automatic breaker that will disconnect and put the circuit into "island mode" if it detects a loss of grid supply

I did it last week. We were out of power for about 30 hours. But I actually have a degree in Computer Engineering, and I did it with a friend who is a professional Electrician.
It is indeed EXTREMELY dangerous. If you don't know what you're doing, or make a mistake, best case scenario, you fry your generator. Worst case, you electrocute a lineman from the power company, who isn't expecting lines to be live when there's an outage, because yes, if you feed power into your house, that will flow OUT of your house onto the main lines (to some extent), if you let it. You could end up trying to power your whole block on your little gas generator.
We made sure both the indoor and outdoor main power shutoffs for the house were turned off, as well as all breakers. Then we unplugged the oven, and used that for the feed from the generator. Then we gradually re-activated breakers so as not to add too much load to the generator at once. Ultimately, we were able to run the whole house, except for the AC compressor, which the generator actually would have had enough power to run, but not to kick-start.
The proper way to hook up a generator to feed your house is to install an "inlet" which is both nominatively and physically the opposite of an outlet: instead of holes going into a box, you have prongs sticking out of a box. Generally, it'll be one of the big fat 4-pronged round cables, like what your oven might use. That'll feed down to a large double-breaker, in the top-right slot of your breaker panel. That breaker stays off until you want to run a generator, and, to meet code, you have to also install a special bracket that prevents you from turning this breaker off without turning off the primary feed for the whole house. Still kinda dangerous, but they make those brackets surprisingly foolproof.
