Well, my follow-up is late, considering I thought this was a dead thread...
Haven't we had threads in the past in which it's been said that in the 50s/60s some areas commonly used red for the high leg?
Nicknames for the 208V-to-ground phase of a four-wire delta:
high leg
wild leg
stinger leg
red leg
orange leg
bastard leg
Have I missed any?
Also, is there any country besides the USA which possesses such a strange beast?
There may have been some areas that used red. Anybody know?
Here in Austin the colors for 208 service are red-black-blue, and have been since at least WWII. For delta they are red-orange-black (B-phase being 208). On old deltas (usually '50s), I've found red-black-blue, and the blue is always the high leg.
I've even found this on single-family residences from the '50s. The earliest central air conditioning systems apparently required 3-phase ('round here we take our air conditioning
seriously!)
