What is the Correct Way to Install Electrical Outlets: Ground Up or Down?

Ask an electrician which way a receptacle, or outlet, should be installed: “Ground up or down?” Typically, the response is “both are fine,” but most of us have a preference. The National Electrical Code (NEC) does not specify an orientation, so you can put them any way you wish, including sideways or on the floor.

If we tend to believe that one method is “right,” why are they occasionally installed with the grounding connection up? Is one superior to another? What should you do within your home? Let’s dig in below.

Why Are Receptacles Installed Ground Up?

Proponents of installing ground-up receptacles point to the risk of short circuits if something metal falls on the exposed blades of a partially plugged-in wire. Plugging in the cord with the grounding pin on top may provide some protection by deflecting a falling object. Ground-up receptacles are prevalent in hospitals, where electrical arcs from a short circuit could be extremely disruptive.

To distinguish between conventional and switched receptacles, electricians may occasionally install ground-up versions. Dryers and other appliances with huge, bulky plugs are generally better suited to “upside-down” receptacles.

There’s also simple preference or habit. Many people were taught a specific way to install a receptacle, and because either direction is valid, they stick with the method they learned. Local codes or special customer requirements may also influence their course of action. Early patents for grounding-type receptacles show the grounding prong on top, so there’s that as well.
