Vertical weatherproof cover for 30 A Hubbellock

The Hubbellock HBL20405 is a single-gang cast-aluminium cover designed for vertical mounting on FS or FD weatherproof boxes. It accepts 30 A, four-wire Hubbellock receptacles and meets UL and Canadian safety standards. Installers working on outdoor or wet-location circuits will find the self-closing lid and included mounting screws simplify code-compliant assembly.

Self-closing lid maintains seal during repeated use

A neoprene gasket and spring-loaded lid work together to reseal automatically after each insertion or removal of a plug. The cast-aluminium body resists deformation when mounted on vertical surfaces exposed to vibration or incidental impact. This behaviour keeps the enclosure rated for wet locations throughout daily service cycles rather than only during initial inspection.

Low thermal mass and no active cooling required

The aluminium cover dissipates ambient heat passively and adds negligible thermal resistance to the receptacle beneath it. With no moving parts beyond the lid hinge, operation is silent and power draw is zero. The neoprene gasket remains flexible across normal outdoor temperature ranges, preserving the weatherproof seal without maintenance.

Questions about this item

How much heat does the HBL20405 cover dissipate when the 30 A circuit runs continuously?

The cast-aluminium cover with neoprene gasket is a passive enclosure; it adds no active cooling and its thermal dissipation is not rated by the manufacturer.

Which mounting box must I already have to install this vertical weatherproof cover?

It fits FS or FD weatherproof boxes and includes the mounting screws for that installation.

Will the self-closing lid on this cover clear the plug on my existing 30 A 4-wire Hubbellock receptacle?

Yes, the cover is designed specifically for 30 A 4-wire Hubbellock receptacles so the lid closes over the plugged-in connector.
