What is an AFCI breaker?

An arc fault circuit interrupter (AFCI) is a circuit breaker designed to prevent fires by detecting non-working electrical arcs and disconnect power before the arc starts a fire. You can read more at wikipedia or at the U.S Consumer Product Safety Commission.

The use of these safety breakers were written into Canadian code, in January 2002. Code and products are always changing. Next time your Electrical Contractor is in your house ask him/her to ensure your electric service is safe and up to code.
