Thread: Question about service drop and window

Hello all,
My first post and question here.
I know that a service drop can't be located within 3" of a window, but what if it's a fixed picture window? Does that still apply?

I appreciate all the knowledge available to me from this site. Thanks.

Tony

TD: I think you meant 3' and not 3". The rule applies to operable windows, and not fixed pane units.

Here's the applicable code:

230.9 Clearances on Buildings.
Service conductors and final spans shall comply with 230.9(A), (B), and (C).
(A) Clearances. Service conductors installed as open conductors or multiconductor cable without an overall outer jacket shall have a clearance of not less than 900 mm (3 ft) from windows that are designed to be opened, doors, porches, balconies, ladders, stairs, fire escapes, or similar locations.
Exception: Conductors run above the top level of a window shall be permitted to be less than the 900-mm (3-ft) requirement.

"230.9 Clearances on Buildings.
Service conductors and final spans shall comply with 230.9(A), (B), and (C).
(A) Clearances. Service conductors installed as open conductors or multiconductor cable without an overall outer jacket ..."

That's odd, if I remember correctly, a cable is defined as;
2 or more conductors with an insulating overall outer jacket.

Yep, meant 3'. Thanks for the replies, that's what I thought.

First, the outer jacket is not "insulating", it is for "protection", and, yes, you can have cable with or without an overall outer jacket.

The service drop cable you see is multiconductor cable without an overall outer jacket, NM cable is multiconductor cable with an overall outer jacket.
