Product identity

The Dayton 26WA81 is a 1,800 W incandescent photocontrol designed for dusk-to-dawn lighting automation in commercial or industrial settings. It suits facility managers and electricians who need a raintight, UL Listed switch for outdoor circuits up to 277 V AC.

Thermals noise and power

The polycarbonate housing operates reliably from -40 °F to 158 °F without active cooling, so it adds no audible noise to the installation. Power draw is limited to the control circuit itself, with a maximum ballast rating of 4.6 A and incandescent rating of 9 A at the stated voltage range.

Installation fit

A 1/2 in conduit flush mount with an included lock nut and washer gasket secures the unit in a standard knockout, while the compact 2 7/8 in length leaves room inside crowded enclosures. The SPST contact form provides a simple on-off path for single-circuit loads, and the 10.0 to 20.0 foot-candle turn-on threshold with 30 to 60 foot-candle turn-off prevents nuisance cycling in variable ambient light.

Questions about this item

How do I install the 26WA81 photocontrol and what is the step people often miss?

Mount it through a 1/2 in conduit opening using the included lock nut and washer gasket; the step often missed is tightening the gasket to keep the raintight seal.

What maintenance or replacement will the 26WA81 need later?

The polycarbonate housing and SPST contact are sealed; no user-serviceable parts exist, so replacement is only needed if the unit fails to switch at the 10.0 to 20.0 foot-candle on point or 30 to 60 foot-candle off point.

What limit appears first when the 26WA81 runs continuously at full load?

The 9 A incandescent or 4.6 A ballast current rating at 208 to 277 V AC will be reached before the -40 to 158 °F temperature range becomes a factor.
