Question:
Thanks for the great Code discussions. How is the new NEC written to install service entrance cable over flat roofs? Stephen Douglas
A
Answer:
Hi Stephen,
The rules for clearances for service conductors installed over roofs are found in Section 230.24(A). The general clearance requirement is not less than 8 feet, but there are allowances based on the pitch of the roof and distance from the edged. See the entire text of Section 230.24(A) and the exceptions for alignment with your specific situation.
