Hey guys,
Doing basement development at parents place right now and we going to be installing an Arc Fault breaker for the basement bedroom, however, the guys in the store said we have to use blue NMD-90 cable. Is that really the building code now? I saw no mention of blue cable anywhere on city of Calgary website? I have a ton of white cable and would really love not to have to buy freaking blue one just for the one bedroom, as I would spend just as much on it by the meter as a full 75M roll of white stuff.
Please advise. Is this really the law or just a preference?
