Why? If you have the breaker off like you're supposed to, the voltage between
all the wires will be -zero- regardless of how the circuit is wired.

It's no surprise anyway if you know what you are doing. 3 colours in
the box means their's 220 in there somewhere. Splits will have both
red and black "lives" plus the white "nuetral"


Not correct. Three colors in the box means there *might* be 240V in there
somewhere. It could also mean switched and unswitched 120V.

You are correct. But I stand by my statement - 220 is NO SURPRISE if
you have both a red and a black wire.


I'm going to suggest a slight rephrase:

220 SHOULD be no surprise if you have both a red and black wire.

If it is a surprise, you have no business futzing with wiring.

[In realith, 220 shouldn't be a surprise even if you only have
a black and white wire. Think 220-only circuits. Like electric
baseboards and perfectly legal practise of using ordinary wire,
rather than the somewhat less common black+red+ground/no white
wire.]
