Question: A residential garage, attached to a dwelling unit, has a 120 V, 15 A general-purpose receptacle. This receptacle is installed less than 1.5 m (5 ft) from the floor and supplies power to a temporary workshop setup. What specific protection is required for this receptacle according to the Canadian Electrical Code?

Answer options:

  • Arc-fault circuit interrupter (AFCI) protection only. ✅ Ground fault circuit interrupter (GFCI) protection only.
  • Both AFCI and GFCI protection.
  • Neither AFCI nor GFCI protection is strictly required for this specific application.

Correct answer: Ground fault circuit interrupter (GFCI) protection only.

Explanation: CEC Rule 26-704(1)(d) requires all receptacles in a garage to be protected by a Class A ground fault circuit interrupter. CEC Rule 26-704(1)(a) lists locations requiring AFCI protection and garages are not included. Therefore, only GFCI protection is explicitly required.
