They also use the same colors for 347/600 and 120/208.Welcome, eh!
The hosers that picked the LV colors for Austin must have been from the Great White North.
Supposedly, its because the city owned electrical utility delivers power "CBA".
CANADIAN WIRE COLOR CODES FOR AC POWER
In Canada, wire color coding standards are set by the Canadian Electric Code (CEC). The color code for AC power wiring is similar to the code used in the United States (and the same as Austin, TX):
Phase 1 - Red
Phase 2 - Black
Phase 3 - Blue
Neutral - White
Ground - Green with Yellow Stripe
Yes, that's close to what it is, PVC coated MC. Actually is it XLPE conductor insulation (XHHW-2), then a PVC inner jacket (like Tray Cable), an aluminum armor like MC, then another PVC outer jacket. MC, even the versions with the outer jacket, doesn't have the inner PVC jacket, usually it just has a clear mylar sheath.All I know about Canadian wiring practices is they use this stuff called Tek cable. Sounds like coated MC?
