This rule is required to be applied when inspecting Mobile Homes, it is the only place that I am aware of in the NEC that gives a specific orientation requirement.
As I said before, the argument is very old! I have records, and reports and even articles that I wrote for EC&M that discussed the many different proposals that asked for the end of the argument.
This will never happen!
The picture above, of the receptacle showing arcing, was intended to make us aware of the condition that could be present when a metal plate falls off of the receptacle when the 6/32 is loose, or falls off and is missing when some school kid decides to have some fun with a teacher who has something plugged into the receptacle.
A two wire transformer, used for printers, PDA's, or other devices will always result in this arcing, so the best advise that can be given is to replace the metal plates with plastic plates.
I actually own this receptacle because one of my students sent it to me for show and tell.
I am also happy to see Dennis come aboard again, welcome back and you may be busy if you read some of the previous messages and replies where we discussed items that I am sure will be familiar to you.
I await your replies and resurfacing of the issues that were covered.
Naturally, I am always happy to hear meaningful and qualified replies from those who are "qualified persons"!
