ECN Forum Forums Code Related Discussion Canadian Electrical Code Topics T rating of a switch

Rob,
Welcome to ECN,
What sort of a switch is this and what sort of application is this being used in?
I suspect that the T rating, as you refer to is the Thermal Current rating.
Switches, if they are going to be used to interrupt/make inductive loads depend heavily on "AC Ratings", like AC-3 or the like, otherwise the switch contacts will be seriously damaged by the arc created when the contacts open or close.
