Need good reference for Nema 4,4x,12 wiring practices
Need good reference for Nema 4,4x,12 wiring practices
(OP)
Anyone have a good reference (electronic or book) that details the specific requirements for an electrical installation to be classified Nema 12, Nema 4, and Nema 4x. I work for a company that is an OEM of pkg equipment and could use a good reference for these situations. Including allowable enclosure penetrations, enclosure and cable types, etc.
Thanks.
Thanks.

BuzzP is right. The standards aren't that expensive, and if you're in a reasonably big city they'll be available at a public library (Memphis has 'em). My company uses them all, so we have a set. They're fairly detailed about testing, so a summary won't really do. Wiring practices aren't covered, just enclosures. Wiring methods are in the NEC.
Good luck!
