I need to wire an Appleton pin & sleeve plug & receptacle for a mobile generator feeding a transfer switch (240V/120V 3-phase delta). The plug/receptacle is AP20044ERS/AR20044RS (200A 4-wire/4-pole); both are Style 1 (grounding on the shell only). The four pins/sleeves are for L1, L2, L3, & N (there is a lug inside the aluminum shell for bonding the ground). None of the pins/sleeves are labeled for phases/neutral inside the plug or the receptacle.
The only open standard I can find for wiring industrial connectors is IEC 60309, but that doesn't apply to the older North American pin & sleeve connectors like this Appleton. The Appleton catalog does not discuss the details of wiring any of their connectors. I do see references to UL 1682 & UL 1686 specifications, but I can't find any open source of the specification. I can't believe I would have to purchase these standards at over $500 each just to learn the correct way to wire these connectors. On the other hand, I can't believe that the wiring of the phases/neutral is completely arbitrary and left to the discretion of the installer at every site. That would mean each site installation would be unique and not interchangeable.
What am I missing here?
