Electrical Code/Drafting Practice • Duplex convenience outlets (wall plugs) should be a maximum of 12’ apart. Closer spacing is desirable, although economy is a factor. Code reads: “no point along a wall is further than 6’ from an outlet. ” • Duplex convenience outlets should be no more than 6’ from a corner • There should be a duplex outlet in any usable wall space over 2’ long • Place a (one) duplex outlet in a hallway

Outlet Placement Example

Electrical Code/Drafting Practice Kitchen /Bathroom areas – usable counter space of 12” & greater require an outlet – outlets are required every 48” of counter space (with new code text is in error) – note mounting height for outlets above counter (+44”) – special purpose outlets for garbage disposal, dishwasher, separate oven, and hood – range outlet for electric range – GFI or GFCI protection for any outlets in rooms with a water source.
