 Supersized the tread has gone on as long as it has. Haven't read a new idea or thought is quite a while now. It's probably past it's bedtime and should be instructed to go to sleep.

Natural rubber for example is black, so maybe they first insulated live wires with rubber? I really don't know, but either way they had to choose colors at some point and no matter what they chose somebody is eventually going to wonder why.

Knob and tube wiring typically used black rubber coated cloth insulation for both the hot and neutral wires.

When polarized AC outlets were introduced, white was probably chosen for the neutral wire as the logical opposite to black, and also because other colors tend to fade over time.

In U.S. wiring, the hot wire isn't actually required to be black. It just has to be some other color besides white, gray, or green.

Is there someone forcing you to read this stuff? You do know you can enjoy every other part of EEVBlog without ever seeing a post in this thread again if you want?

Come to think of it, your post is exactly why this thread exists: someone decides they don't like something and figures everyone else should feel the same.
