Position an outdoor receptacle at least 16 inches above the ground. An in-use cover increases protection from the weather. A simple wooden box built around it shields it from bumps by the lawn mower or kids at play. Outdoor receptacles must be GFCI-protected. Check local codes for approved cable, conduit, and boxes.
The quickest way to extend power outdoors is to install a receptacle back-to-back with one inside the house. You also can drill through the wall from a basement or crawlspace and attach a receptacle on the side of a house using an extension ring.

Can I tap into an existing circuit and still be within code?
1/26/2010 08:26:30 AM Report AbuseHow do you know if you are following code? I would like to install a sump pump (9 amp) next to the house (for yard drainage). Can I tap into an existing circuit and still be within code? The easiest circuit to tap is labeled "hallway" on the panel, is 20 amp, and has already been tapped into for a heat pump water circulator (7 amp).
