Service point on roof

[Greg Fretwell]

From the handbook

BTW note the word "span" is not used in the 18" exception

Exception No. 3: Where the voltage between conductors does not exceed 300, a reduction in clearance above only the overhanging portion of the roof to not less than 450 mm (18 in.) shall be permitted if (1) not more than 1.8 m (6 ft) of service-drop conductors, 1.2 m (4 ft) horizontally, pass above the roof overhang, and (2) they are terminated at a through-the-roof raceway or approved support.

[Marc D. Shunk]

Neither the NECH commentary or the accompanying illustrations modify the base code text. The exception is an exception to the base rule which does reference "span".

...and open multiconductor cables. I will simply fail the SE part past the service point.
