service conductors without required clearance

What’s Wrong Here? Hint: A Window with a View… of Conductors!

Dec. 22, 2022
Think you know how this installation violates the NEC?

Hint: A window with a view…of conductors!

Section 230.9(A) requires service conductors to have a minimum clearance of 3 ft from doors, porches, balconies, ladders, stairs, fire escapes, and windows that are designed to be opened when the conductors are installed as “open conductors” or multiconductor cables without an overall outer jacket. These conductors are right next to the window and can be easily reached when the top window is opened. Since these conductors are not installed entirely above the top level of the window, the exception of allowing less than 3 ft of clearance from the window would not be applicable.
