Industrial 50 A Straight Blade Plug
The Hubbell HBL7513C is a 3-wire, non-grounded straight blade plug rated for 50 A at 125/250 V AC single phase. Its corrosion-resistant nylon housing carries an IP20 rating and UL 94 HB flammability classification. Screw terminals accept cable diameters from 0.625 in to 1.218 in for secure field wiring in harsh environments.
Verify NEMA 10-50P Compatibility
Confirm the receptacle matches the NEMA 10-50P configuration with three blades and three poles. Ensure the circuit supplies single-phase 125/250 V AC and that the application does not require a grounded connection. Check that the cable outer diameter falls within the 0.625 in to 1.218 in range for proper terminal fit.
Replaces Worn 50 A Non-Grounded Plugs
This plug directly replaces damaged or aged 50 A straight blade plugs using the same NEMA 10-50P layout. The upgrade is worth it when the existing housing shows cracking, corrosion or terminal loosening that compromises the 2 hp or 3 hp motor circuit. It restores a polarized, corrosion-resistant connection without changing the wiring scheme.

Questions about this item
What comes with the HBL7513C plug and what must I source separately?
The package contains the straight-blade plug with screw terminals and a nylon housing rated IP20; you must supply cable between .625 in and 1.218 in diameter and any strain-relief hardware.
How do I decide between the 125 V and 250 V ratings on the HBL7513C?
The device is rated for 125/250 V AC single-phase; choose the voltage that matches your supply and the 50 A load you intend to run.
What does the 50 A rating mean when the HBL7513C is wired into a real circuit?
It indicates the maximum continuous current the screw terminals and 10-50P blades can carry at 125/250 V AC, with a 2 hp motor load at 125 V or 3 hp at 250 V.
