Questions about this item
What amperage circuit must I already have for this 20 A toggle switch to operate safely?
The switch is rated for 20 A at 120 to 277 V AC, so the branch circuit and breaker must support that same 20 A capacity.
Will the back-and-side wiring terminals accept the same conductors I use with older Bryant switches?
Yes, the 4903 provides both back-wire and side-wire terminals, matching the wiring method found on earlier Bryant industrial toggle models.
How can I confirm the 3-way circuit is wired correctly after installation?
Toggle each switch position; the load should turn on and off from both locations without binding, indicating proper traveler and common connections.
