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.
It also backfeeds the grid and can kill someone working on the lines.
This is the real issue and why you need a modern transfer switch. Lineman is working on the transformer on the pole, “it’s fine we cut it off upstream and I checked” and BOOM anyway
This is all reasonably accurate. Source: electrician, who worked at a supply store for a while. I’ve had people ask how to make all kinds of stupid cords.
If you don’t know what you’re doing, don’t fool with electricity
The problem is that people read a few things on the internet, think they’re now suddenly domain experts, and do it anyway.
Oh I know.
I’ve talked to them.
Don’t do it. If you haven’t actually worked with an electrician for at least two or.three years, just leave the repairs and shit jobs for people like me.
If you can’t explain why the white wire is incorrectly called a neutral in single-phase systems, don’t touch it.
