Question: A Red Seal electrician is installing a new 30 A, 240 V electric stove in a residential dwelling. The existing circuit consists of 10 AWG copper conductors run in NMD90 cable. What is the maximum continuous load permitted on this circuit according to the Canadian Electrical Code (CEC)?
Answer options: ✅ 24 A
- 30 A
- 20 A
- 21 A
Correct answer: 24 A
Explanation: According to CEC Rule 8-104(1) and Table 2, for circuits supplying continuous loads, the maximum continuous load shall not exceed 80% of the rating of the overcurrent device, or the ampacity of the conductors, whichever is less. For 10 AWG copper, the ampacity is 30 A (Table 2, NMD90). Therefore, 80% of 30 A is 24 A. This question tests the understanding of continuous load calculations.
