- 1 HP motor rating drives equipment directly
- 14–10 AWG screw terminals accept common wire sizes
- Shatter-resistant nylon housing withstands impact and corrosion
Single-Pole 20 A Switch
The Hubbell CSB120I is a commercial-grade toggle switch rated for 20 A at 120/277V AC. Its single-pole design controls one circuit from a single location. The ivory nylon housing resists shattering, cracking, corrosion and impact. It suits electricians and facility managers wiring lighting or motor loads in commercial buildings.
Back and Side Wiring Options
The device accepts both back and side wiring methods using screw terminals. Conductors from 14 AWG to 10 AWG can be terminated without special tools. This flexibility lets installers choose the fastest method for the box fill and cable type on site. The 1 hp rating supports small motor loads directly.
Straightforward Screw-Terminal Install
Installation follows standard single-pole practice: strip wire, loop under the terminal screws and tighten. The nylon body withstands job-site handling but can crack if terminals are over-torqued. Ensure the box depth accommodates the switch body and wiring folds. Not suited for buyers needing multi-location control or dimming functions.

Questions about this item
How often should the 10 AWG screw-terminal connections on the CSB120I be inspected and retorqued?
Inspect and retorque the 10 AWG screw-terminal connections annually or after any vibration event to maintain reliable contact.
What is the first limit reached when the CSB120I runs continuously at its 20 A rating?
The 1 hp motor-load rating at 120 V AC is the first limit reached under sustained 20 A use.
Does the nylon housing of the CSB120I get hot or make noise when the 20 A circuit runs all day?
The nylon housing stays cool and silent; the switch has no moving parts that generate heat or noise during continuous 20 A operation.
