If it is impractical to locate the service head above the attachment point, the maximum distance between them is?

• A. 12 inches
• B. 24 inches
• C. 36 inches
• D. 48 inches

Answer: (B)

When wiring overhead service conductors, the weatherproof service head (the point where the conductors come together) should be located directly above the point where the service enters or attaches to the building. If it’s not practical to place it right above that attachment, the code allows a limited horizontal offset. The maximum allowed distance is 24 inches. This limit keeps the weatherproof connection reliable, maintains a proper drip loop to shed water, prevents undue tension on the conductors, and preserves required clearances. Distances shorter than 24 inches may be workable but unnecessary; distances longer than 24 inches would compromise weatherproofing and code compliance.
