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.
