    Is it style Z not class Z?
    They say I shot a man named Gray and took his wife to Italy
    She inherited a million bucks and when she died it came to me
    I can't help it if I'm lucky

    I suspect it’s Type Z listed in Table 310.104(A) for special applications. Basically we would call it Teflon if that weren’t a trade name.

    I took a test and the question was. Which would be classified a class Z wiring method of an oil burner heater? A) Firematic B) Thermostat C) Motorized zone damper D) B & C.
    I've never heard of Class Z wiring meathod and maybe it was just a typo and should of been class 2
