Electrical Plans In habitable rooms, duplex outlets should be placed a maximum of 12 feet apart along the wall line.

Duplex outlets should be no more than 6' from an opening.

Each wall over 2' in length must have an outlet.

Outside duplex outlets should be placed at a convenient exterior location, such as a patio.

Electrical Plans *All exterior outlets must be waterproof and GFCI. The letters WP are used to identify the cover plate on exterior duplex outlets.
