[QUOTE="Evans Electric, post: 69599, member: 1408"] Picture the typical Bill or MEM metalclad industrial switchfuse or isolator . When switched on it shows red in the indicator window. (Red for danger) When switched off it shows green . ( Green for safe) The older ones ( 1960s-70s) which look exactly the same are the opposite. When switched on it shows green in the window. (green for go) When switched off it shows red in the window. (Red for stop) The position of the handle is the same but someone could glance at the isolator , see green and assume it is off. ( For the pedantic, Yes I know he should test it) The colour change crept in and I can't remember any publicity about it . [/QUOTE]
