Watertight 20 A 250 V Connector

This Hubbell straight-blade connector provides a grounded, watertight power connection rated for 20 A at 250 V AC. It accepts cables from 0.38 in to 0.63 in diameter and uses screw terminals for secure wire termination. The yellow HAWA housing resists corrosion and impact for demanding environments.

Press-On Cap and Screw Terminals

A press-on cap seals the connection point against moisture and debris when the connector is not mated. Screw-terminal wire connections allow reliable field installation without specialised crimping tools. These features support quick maintenance and durable performance in wet or outdoor locations.

20 A Single-Phase Capacity

The device handles single-phase loads up to 20 A and 1 hp motor loads within its 250 V rating. It is not suited for circuits exceeding 20 A, three-phase power, or cable diameters outside the 0.38 in to 0.63 in range. Builders needing higher current or multi-phase configurations must select a different connector.

Questions about this item

How often should the screw terminals be checked after the initial installation?

Inspect the screw terminals after the first hours of operation and then at regular maintenance intervals to ensure a secure connection under vibration and thermal cycling.

What cable diameter range fits the connector and prevents water ingress?

The connector accepts cables from 0.38 in to 0.63 in outer diameter; using cable outside this range will compromise the watertight seal.

How hot does the housing get when carrying 20 A continuously?

The housing is rated for 250V AC and 20 A continuous duty; temperature rise depends on ambient conditions and cable size, so monitor during initial sustained loads.
