We ran into some TW75 cable in a recent installation, and I'm perplexed, as it's not listed in NEC. Is TW75 the canadian version of THW? Are the two identical aside from the labling, or is there some difference? Is TW75 legal to use in the US?

Steve:
Looks like no one wants to touch this one.
'TW' is 60c; THW is 75c.....that's all from 310.13
Perhaps 'TW75 in Canada is rated 75c??
Best guess, no facts
