Question: A journeyperson is connecting a 20 A, 120 V circuit to a duplex receptacle in a dwelling unit bedroom. Which of the following statements regarding the receptacle connection is correct according to CEC?
Answer options:
- Both halves of the duplex receptacle must be connected to the same ungrounded conductor.
- The receptacle must be a Ground Fault Circuit Interrupter (GFCI) type. ✅ The receptacle must be Arc Fault Circuit Interrupter (AFCI) protected, but not necessarily GFCI.
- The receptacle must be connected via #14 AWG copper conductors.
Correct answer: The receptacle must be Arc Fault Circuit Interrupter (AFCI) protected, but not necessarily GFCI.
Explanation: CEC Rule 26-710(1) requires that all 125 V receptacles rated 20 A or less, installed in dwelling unit bedrooms, shall be protected by an Arc Fault Circuit Interrupter (AFCI). There is no general requirement for GFCI protection in bedrooms. #14 AWG copper conductors are rated for 15 A, so for a 20 A circuit, #12 AWG conductors would be required, as per CEC Rule 14-100 and Table 2.
