There certainly are!!!

The correct way to wire a 120VAC receptacle is as follows:

Looking at the receptacle face on, the ground pins should be aligned 
downwards. This will result in the larger of the two prongs aligned 
to the left. This larger prong is the Neutral. The smaller prong is 
the Live. Also the live is usually indicated by a brass-type metal 
screw, while the neutral is usually silverish in appearance.

Also, avoid plugging interconnected gear into receptacles on opposite 
walls of a house- agreat way to destroy gear and life.

Be careful.
