Thanks Bob. I've also had it pointed out to me that the writing on the sockets themselves is usually oriented ground-up, and some are even marked "TOP" with ground-up orientation. Seems to be a preference but not a requirement.

Proposals to establish an orientation have been proposed to the code panel and rejected. See http://electrical-contractor.net/ubb/Forum2/HTML/000553.html for a discussion. You will find ground up preferred by some to provide protection as mentioned by Art Michaels. However, you will find many direct plug in products configured with ground down. Dimensions for these and twist lock plugs are in NEMA standard WD6-88. Sorry, I don't have a copy. Bob Johnson ITE Safety -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Jim Eichner Sent: Friday, July 19, 2002 1:40 PM To: 'EMC-PSTC - forum' Subject: Nema 5-15R sockets A couple of questions about our standard North American 120Vac socket: 1. Orientation: We have lots of people in the office here on both sides of this one, and I can't find a normative reference in the CEC or the NEC. Which is the correct way "up" when installing a socket on a wall - ground pin above the L and N blades, or L and N above the ground? What is the code reference for this requirement, or is there none? 2. Dimensions: Can anybody share the spec's for the dimensions, with tolerances, of the line, neutral, and ground blades for this configuration? I'm sure it's in the UL and CSA standards but I don't want to spend hundreds of $ for a one-time question. We have no on-going need for these standards!
