Straight Blade Inlet 20 A 125V AC

The Hubbell HBL5378C is a straight blade inlet rated for 20 amps at 125 volts AC. Its white thermoplastic housing resists impact in demanding environments. Backwired terminations and #8-32 multiple drive terminal screws simplify wiring tasks. Mounting screws are supplied for immediate installation.

Indoor fixed wiring installations only

This inlet suits electricians and maintenance teams wiring permanent 20 A 125 V circuits in commercial or residential buildings. It is not for cord-connected portable equipment, outdoor exposure without a weatherproof cover, or circuits exceeding the rated voltage and current. Buyers needing higher amperage or different pin configurations should select another device.

Backwired terminations speed mounting

Strip conductors, insert into the backwire openings, and tighten the #8-32 terminal screws with a standard driver. The multiple drive heads accept Phillips, slotted, or square bits. A common error is over-torquing the screws, which can crack the thermoplastic base. Verify the circuit is de-energised before starting work.

Questions about this item

What circuit rating must the branch circuit provide for this 20 A 125V AC inlet?

The inlet is rated for 20 A at 125V AC, so the supplying branch circuit and breaker must match that 20 A 125V AC rating.

Will the included #8-32 mounting screws fit the same holes as my older Hubbell inlet?

The #8-32 multiple-drive terminal screws and included mounting screws follow Hubbell's standard pattern, so they align with existing Hubbell inlet cut-outs.

How can I confirm the backwired terminations are secure after installation?

Tug each conductor firmly; the backwire clamps hold the wire without needing the terminal screws tightened, and the multiple-drive screws can be snugged as a secondary check.
