Marinco Bumper Plug
Mounting with the ground up is very common in the industrial setting and is getting more common in residential (depending on code). The reason behind it is if something falls on the plug and slightly knocks it out of the outlet it will land on the ground and won’t hurt anything. If mounted ground down it will land on the common and hot and will cause problems.<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com
