What's Wrong Here?

Sept. 23, 2005
Hint: This green light means “stop.”

How well do you know the Code? Think you can spot violations the original installer either ignored or couldn't identify? Here's your chance to moonlight as an electrical inspector and second-guess someone else's work from the safety of your living room or office. Joe Tedesco, who has a knack for finding shoddy electrical work, did the dirty work and found this mess. Now it's your turn to identify the violation.

Find the Answer

Answer:

This service drop and associated service entrance conductors are too close to the window that can be opened. Per 230.9, 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.

An exception permits conductors run above the top level of a window to be less than the 900-mm (3-ft) requirement.
