Hubbell 1222I Double Pole Toggle Switch 20A 277V

Product Description

The HUBBELL 1222I is a heavy-duty double pole toggle switch rated for 20 amps at 120 to 277 volts AC. Built for industrial applications, it features a nylon toggle and thermoplastic body with an ivory finish. The switch delivers a power rating of 1 HP at 120 volts and 2 HP at 277 volts. It includes a one-piece rivetless copper alloy spring contact arm with large silver alloy contacts to reduce erosion and extend service life. A nickel-plated steel bridge resists corrosion. A licensed electrician installs this device as part of branch circuit wiring in commercial and industrial environments, typically during rough-in or panel upgrade work.

The 1222I is suited for industrial facilities, commercial buildings, and heavy-duty residential applications where a robust 20-amp double pole switch is required. It accepts back and side wiring configurations, and the back wire entrance points accommodate two wires per terminal for feed-through capability, eliminating the need for pigtailing. The color-coded base helps identify amperage quickly during termination. Prominent amperage markings on the device further assist techs working in multi-circuit panel environments.

Key Features

• 20A double pole toggle operation rated 120 to 277 volts AC
• Large silver alloy contacts reduce contact erosion for long service life
• One-piece integral grounding terminal with 8 AWG brass screw for low-resistance ground path
• Stainless steel automatic grounding clip ensures continuity between mounting strap and metal wall box
• Back wire entrance accepts two wires per point, supporting feed-through wiring without pigtailing
• Abuse-resistant nylon toggle with color-coded base for quick amperage identification
• Thread-cleaning captive mounting screw and strip gauge for accurate, secure wiring

Compatibility

Designed as an OEM-style replacement or direct-install double pole toggle switch for industrial and commercial branch circuit wiring applications requiring a 20-amp, 120 to 277-volt AC device.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the NEC and applicable local codes. De-energize the circuit at the breaker panel and verify absence of voltage with a meter before beginning wiring. The device supports both back-wire and side-wire termination methods. Use the built-in strip gauge to ensure correct conductor strip length before securing wire connections with the large brass binding head screws.
