Questions about this item
How do I verify the L7-20R connector is wired correctly after installation?
Confirm the line terminals marked X, Y, Z and the grounding terminal marked G are secured, then twist a matching L7-20P plug until it locks; the connector should deliver 277 V at up to 20 A without overheating.
What is included in the package and what must I supply myself?
The package contains the yellow ETL-listed NEMA L7-20R female locking connector only; you must provide a compatible 18–10 AWG three-conductor cord such as SJT, SJTW, ST or STOOW types.
Which amperage rating should I select for a 12 AWG cord on this connector?
Use the 20 A / 277 V rating (5540 W) when wiring 12 or 10 AWG cord; for 14–13 AWG the rating drops to 18 A, for 16–15 AWG to 13 A, and for 17–18 AWG to 10 A.
