Panel-Mount Inlet for 20 A Service
The Hubbell HBL5478C is a flanged inlet rated for 20 amps at 250 volts AC. It provides a NEMA 6-20R single-phase, 2-pole, 3-wire grounding connection for industrial equipment. The device is UL listed and CSA certified for use in demanding environments.
Nylon Housing with Brass Contacts
The body uses a nylon and polycarbonate housing rated UL94 V-2 for flammability resistance. Brass blades and terminal screws accept #18 to #10 AWG copper conductors via backwired screw terminals. Panel mounting screws are included for secure installation.
Replaces Hard-Wired Power Entry
This inlet replaces a permanent cable connection where a detachable cord set is preferred for service or relocation. The jump is worth it when equipment must be disconnected quickly without tools. It does not suit applications requiring a NEMA 5-20 or higher amperage configuration.
