> Probably the least common voltage in Canada. We’ll have some 347V though. Yeah, if you don’t have 480V, extremely unlikely you’ll have 277V. 347V has comparable issues to what I was referring to with 277. 480/600 aren’t voltage you’ll normally find wire nut’s in a jbox or behind say a light switch for example, but 277/347 you will. Unlike 120V though, if something were to cause it to arc (or worse, electrocute you), you’re going to have a very bad day! Not tagging off a circuit is always a bad idea, but especially when voltages are 250+.
