Regarding this the only thing I can say is if the outlet is located where metal objects such as spoons may fall, and the cord may be partially pulled out of the socket, install the outlet with the ground on top. That way a falling object possibly will not contact the hot and neutral legs. But that is a stretch of imagination to think that may happen.
99% of every outlet I can recall seeing has the ground down.
ReplyDeleteSame here. That must be a standard most electricians follow.
DeleteThis came about from the medical field. Several cases of metal(stainless) clipboards falling off carts contacting partially. Exposed prongs on plug
ReplyDeleteThat would explain it.
DeleteWhen I built my house, I installed all with the ground up like you suggest. Horizontal outlets have the common (white wire) up for the same reason.
ReplyDeleteAbout 40 years ago i installed a bunch of outlets, all horizontal. Don't know whether I followed a pattern or not.
DeleteBuilders where I am put the ground up when the outlet is switched, as in for a nightstand lamp in a bedroom. Usually one per room.
ReplyDeleteI don't like wall switched outlets. I have one in this house I still don't know what it goes to.
DeleteThe electrons don't care, it doesn't freakin' MATTER.
ReplyDeleteYep. A matter of preference I suppose.
