Useful side-by-side distinctions
NEMA 5-15 versus 5-20 formsIs the item a plug or receptacle, and does the 5-20 form/T-slot cue apply?↗NEMA L5-20 versus L6-20 locking plugsIs the documented locking plug configuration L5-20P or L6-20P? Connector-family identity is only the first layer; implementation-specific electrical and protocol requirements still need exact documentation.↗NEMA 1-15P versus 5-15P plugsIs the documented plug the non-grounding 1-15P configuration or grounded 5-15P?

Discovery is not a compatibility verdict.
These discovery surfaces route and reorganize facts already represented in the atlas. They do not add electrical ratings, universal pinouts, measured tolerances, exact-device support, wiring approval or an end-to-end compatibility result.
