Question: A journeyman electrician is installing EMT (Electrical Metallic Tubing) for a branch circuit in a dry location. According to the Canadian Electrical Code (CEC), what is the maximum number of 90-degree bends permitted in a single run of EMT between two pull points (e.g., outlet boxes or conduit bodies)?
Answer options:
- Two (180 degrees total)
- Three (270 degrees total) ✅ Four (360 degrees total)
- Six (540 degrees total)
Correct answer: Four (360 degrees total)
Explanation: CEC Rule 12-1110 (2) specifies that the runs of conduit, tubing, or other raceways shall not contain more than the equivalent of four 90-degree bends (360 degrees total) between pull points. This limit helps prevent wire damage during pulling and makes future wire replacement easier. Three bends (270 degrees) would be permissible, but four is the maximum.
