Hubbell HBL4570C Locking Plug
The Hubbell HBL4570C is a NEMA L6-15P locking plug rated at 15 amps and 250 volts AC. Its ribbed nylon housing resists impact and chemicals while giving a firm grip during installation. The individually moulded face matches each blade configuration for a precise fit. This accessory suits technicians and installers who need a secure, twist-lock connection for high-voltage equipment in commercial or industrial settings.
Practical limits of a twist-lock 15 A plug
The L6-15P standard locks the plug into the receptacle so vibration cannot loosen the connection, yet it still tops out at 15 amps and 250 volts. The roomy wiring chamber eases termination, but the device cannot carry loads beyond its rated current or voltage. Installers must ensure the circuit breaker and wiring match the 15 A rating, and the plug will not mate with straight-blade or other NEMA configurations.
The 15 A 250 V rating decides fit
The single specification that determines whether this part works is the 15 amp, 250 volt AC rating combined with the L6-15P blade geometry. If the equipment nameplate calls for a different amperage, voltage or NEMA pattern, this plug will not connect safely. Buyers who need a higher current rating, a different voltage or a non-locking connector must select another device.

Questions about this item
Which amperage rating should I choose for a 15 A 250V AC locking plug?
The HBL4570C is rated 15 A at 250 V AC, so select this version when your circuit and receptacle match those values.
What does the 15 A 250 V AC rating mean once the plug is installed in equipment?
It indicates the plug can continuously carry 15 amps on a 250-volt AC circuit, suitable for locking receptacles wired to that voltage and current.
What does the L6-15P interface cap in practice?
The L6-15P locking configuration mates only with L6-15R receptacles, limiting use to 15 A 250 V AC two-pole three-wire circuits.
