ABSTRACT:
The present invention is a receptacle level that simulates a male electrical plug and also contains a liquid bubble level such that when the device is plugged into an electrical wall outlet, proper orientation of the wall outlet can be obtained by reading the bubble level. The receptacle level includes tapered male plugs and fits within coverplate clearances as are typically used with the electrical wall outlet to be leveled. This device simplifies the leveling of electrical wall outlets during installation.
