The CSA equivalent of IEC 1010-1 is CSA C22.2 No. 1010.1. The National
Forward states that CSA C22.2 No. 0 also applies. This standard specifies in
4.6.1 that 'Terminals that are intended for direct connection to either a
grounded conductor or a neutral conductor of a supply circuit shall be
identified unless their intended use is clearly evident. They shall be
substantially white in colour if colour coded, or be marked "N", "Neutral",
"W", or "White" either on or adjacent to the terminal.'
I have had a CSA engineer in the last month inform me that 120 v circuits
must specify "N" or "Neutral" or "NEUT" and that 240 V circuits must not use
this term.
