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.
