About Black High Temp NEMA L6-30P to IEC320 C21 20A 250V
The NEMA 6-30P is a (hot-hot-ground) grounded plug that is rated up to 250V and 30A. This plug will supply either 208V or 240V based upon your electrical service, and will provide no neutral connection. This is commonly found on in-rack power distribution units where the electrical service is greater than 120V. The locking safety feature prevents this plug from disconnecting without intent.
