Dayton 26WA77 Photocontrol Overview
The Dayton 26WA77 is a 2000 W incandescent photocontrol designed for 120 V AC circuits. It mounts on a 1/2 in conduit in a flush configuration and is suited for outdoor lighting that must switch automatically from dusk to dawn. The gray aluminum housing carries a raintight enclosure rating and UL Listed marking.
Installation Notes and Common Issues
The unit includes a lock nut and washer gasket for the 1/2 in conduit entry, so mounting is straightforward with basic hand tools. Wiring follows a simple SPST contact form rated for 16.7 A on both incandescent and ballast loads. The most frequent problem is overtightening the lock nut, which can crack the gasket and compromise the raintight seal.
Sustained Load Behaviour
Under continuous operation the contacts remain within their 16.7 A rating across the full -40 to 158 degrees F temperature range. The thermal mass of the aluminum housing helps dissipate heat during long nights, preventing the drift that can occur in smaller plastic-bodied controls. The 10.0 to 20.0 foot-candle turn-on and 30 to 60 foot-candle turn-off thresholds stay stable over extended cycles.

What components are included and what must be purchased separately for mounting?
The package includes a lock nut and a washer gasket; 1/2-inch conduit, wiring and any additional sealant are not supplied.
Which rating should I choose for a 120 V AC circuit with a 2000 W incandescent load?
This model is rated for 120 V AC and a maximum of 2000 W incandescent or ballast load at 16.7 A, matching those requirements exactly.
