Blue 20 A 125 V Receptacle

The Hubbell HBL420S is a surface-mount receptacle rated for 20 A at 125 V AC. Its blue polycarbonate housing encloses surge-suppression circuitry rated at 80 joules and 6 500 A per mode, with two 22 mm square MOVs delivering 240 joules of protection for each mode. A nylon component shield guards the conformally coated glass-epoxy board against moisture and contaminants.

Installers needing surge-protected power points

Electricians wiring workshops, garages or light-industrial benches where transient suppression is required will find the device suitable. The three-conductor feed energises all four outlets and break-off tabs allow split-circuit wiring. Buyers who need higher joule ratings, different voltage ratings or panel-mount form factors should look at other models.

Anchor-hole terminals and triple-wipe contacts

Anchor holes with loop features secure solid wire for fast terminations, while triple-wipe contacts improve connection reliability over time. The accessible break-off tabs simplify conversion to split-circuit operation without special tools. These features reduce installation time and help maintain consistent contact pressure in vibration-prone locations.

Questions about this item

Does the HBL420S need a 20 A circuit breaker and 12 AWG wiring to operate at its 20 A rating?

Yes, a 20 A branch circuit protected by a 20 A breaker and wired with 12 AWG conductors is required for the receptacle to deliver its full 20 A 125 V capacity.

Will the triple-wipe contacts and break-off tabs on the HBL420S work with the solid copper wire already in my existing boxes?

The anchor-hole and loop terminals accept solid copper wire for fast termination, and the break-off tabs allow split-circuit wiring with the existing conductors.

How do I confirm the 80 joule surge suppression is active after I wire the HBL420S?

The built-in indicator lights illuminate when the MOV protection is functional; if the lights are off, the surge circuit has sacrificed itself and the receptacle should be replaced.
