Leviton Auto-ON/Manual-ON Power Pack, 120/208/220/230/240/277V AC, 20A

The Leviton Auto-ON/Manual-ON Power Pack is a control accessory designed to interface low-voltage occupancy and vacancy sensing circuits with line-voltage lighting loads. Rated for 120/208/220/230/240/277-Volt AC systems at 20-Amp capacity, this power pack supports both Auto-ON and Manual-ON operating modes, giving installers flexibility to match the switching behavior to the space and code requirements. Its compact housing is finished in gray for straightforward installation above ceilings, in wall cavities, or within fixture housings.

Key Features

  • Dual Operating Modes: Supports both Auto-ON and Manual-ON switching, allowing lights to turn on automatically upon occupancy detection or to require a manual switch action, depending on the application and local code requirements.
  • Multi-Voltage Compatibility: Rated for 120/208/220/230/240/277-Volt AC service, allowing a single power pack to be specified across a wide range of commercial and light industrial electrical systems.
  • 20-Amp Load Rating: Handles up to 20-Amp of connected lighting load, supporting larger fixture groups on a single control zone.
  • Low-Voltage Sensor Interface: Bridges low-voltage occupancy/vacancy sensor control wiring to line-voltage lighting circuits, isolating sensor electronics from the switched load.
  • Gray Finish: Neutral gray housing for unobtrusive placement in ceilings, junction boxes, and fixture enclosures.
  • Space-Saving Housing: Compact enclosure designed to fit within standard ceiling, wall, and fixture-mounted electrical control installations.

Technical Specifications

  • Operating Modes: Auto ON / Manual ON
  • Voltage Rating: 120/208/220/230/240/277-Volt AC
  • Current Rating: 20-Amp
  • Color: Gray

Typical Applications

  • Occupancy and Vacancy Sensor Lighting Control Circuits
  • Commercial Office and Classroom Lighting Zones

Leviton OPP20-D2 – Frequently Asked Questions

1) What does a Leviton OPP20-D2 power pack actually do in an occupancy sensor lighting circuit?
The OPP20-D2 is the interface between low-voltage sensor wiring and the line-voltage lighting circuit. The sensor sends its low-voltage control signal to the pack, and the pack does the actual switching of the line-voltage load, keeping the sensor electronics isolated from the switched lighting. Without a pack like this, a low-voltage occupancy or vacancy sensor has no way to break a line-voltage branch circuit.
2) How much lighting load can one Leviton OPP20-D2 power pack switch?
Up to 20A of connected lighting load on a single control zone. That is enough to put a sizeable fixture group on one sensor rather than splitting the room across multiple packs. If your zone draws more than 20A, or you are switching more than one branch circuit, you need an additional pack per circuit.
3) What is the difference between Auto-ON and Manual-ON, and does this Leviton pack do both?
The OPP20-D2 supports both modes. Auto-ON turns the lights on by itself when the sensor detects occupancy. Manual-ON requires someone to hit the switch, and the sensor only handles the turn-off, which is what many energy codes call for in offices and classrooms. Because one pack covers both behaviors, you can set the switching to suit the space and the code requirement instead of ordering a different part.
4) Where does the Leviton OPP20-D2 power pack get mounted?
It is built for above-ceiling, wall-cavity, or fixture-housing installation, so it lives out of sight near the load rather than at the switch location. The compact gray enclosure is meant to sit in ceiling spaces, junction boxes, and fixture enclosures.
5) Can I add occupancy sensor control to an existing lighting circuit without rewiring the whole zone?
That is the normal use for this Leviton pack. It is listed for retrofit lighting control upgrades: the pack goes in above the ceiling on the existing line-voltage circuit and the new low-voltage sensor runs to it, so the branch wiring and fixtures stay as they are. The 120 through 277V AC rating means you do not have to identify the system voltage before specifying it, as long as it falls in that range and the zone is 20A or less.
6) Does the Leviton OPP20-D2 include the occupancy sensor?
No. The OPP20-D2 is the power pack only, a control accessory that switches the line-voltage load on command from a low-voltage sensing circuit. The occupancy or vacancy sensor is a separate item and is ordered alongside it.
7) What is the exact Leviton part number for this 20A auto/manual power pack?
Leviton OPP20-D2. It is a single-model item, so there are no finish or voltage suffixes to choose from; the gray housing and the 120 through 277V AC, 20A rating are all one part number.
