In North America, these switches are UL recognized and CSA certified as Supplementary
Protection devices. Per the intent of NEC (National Electrical Code), Article 240, and CEC
(Canadian Electrical Code), Part 1 C22.1, supplementary breakers cannot be used as a
substitute for the branch circuit protective device. They can be used to provide overcurrent
protection within an appliance or other electrical equipment where branch circuit
overcurrent protection is already provided, or is not required.
