Electrical question

Sometimes i use brown, orange, and yellow. Lol
White wires are often used for hots, and if they are, they simply need a single band of black or red, or even blue phase tape..
Some of our residential houses have 240v 3phase services, they will have a 3ph meter, but only a single ph breaker panel.. the 3 phases will go from the meter to a 3ph disconnect, then straight to the a/c.

Would love to see some comments on a "california 3way" lol
Its how old timers wired 3way switches without travellers.
Basically, you use 2 3way switches, you wire the hot and neutral to each switch, then wire from each switch to the light., haha
The light works when it gets a hot from 1 switch and a neutral from the other.
Flipping a switch, the light goes out because it has 2 neutrals... or 2 HOTS, lmao

A meter comes in handy most of the time, just sayin.

I’ve seen that once in 30+ years.

If you cant find the breaker to shut off the control power.. it might be because someone tapped the feeder, lol

I see california 3ways odten, in nearly all of these old early 1900s homes

This is the crap i deal with, old "A-base" style meters, these meters are "hard wired", you cannot unplug the meter.. you have to de-terminate the wires, while hot.. and usually the insulation breaks.. is brittle from being overheated.

Then, theres lots of indoor fuse boxes, mounted outside.!

Heres a good one i found recently. Its a 480v 3ph feed to a twist lock outlet on a column, for a welder.. no telling how many years it had been operating like this.. basically, the brown didnt get stripped when terminated.. but it still made enough connection when the voltage blew thru the thin flattened insulation.. smh

[Zmaxhunter]

Heres another beauty..! Just kept adding wires to more fuse boxes or other loads. Another indoor fuse box mounted outside.. very large old home, 60amp service, they never upgrade them.. they just add on to what theyve got.. sad

Can see where it was burning up on the center.. neutral

A 5 wire system? Please explain? Or pictures would be better to see what’s wired wrong.

[Zmaxhunter]

3phases, neutral, ground... 5 wires

He said to a residence? Never heard of a three phase residence?

He didn’t say it was a 5 wire system...
He just said he used those colors.
It doesn’t make anything “wrong”.

Not common, but I have.
It was 480v 3 phase...You can get what you want if you’re willing to pay.
