Leviton OPP20-D1 – Frequently Asked Questions

1) Will the Leviton OPP20-D1 power pack work on a 277V lighting circuit, or is it 120V only?
It runs on either. The OPP20-D1 is rated 120/277V AC line voltage, so the same unit serves a standard 120V branch circuit or a 277V commercial lighting circuit. That means one part number covers both the office and the warehouse side of most buildings, which is why contractors stock it for mixed-voltage jobs.
2) How much lighting load can a Leviton OPP20-D1 power pack switch?
The OPP20-D1 is rated 20 amps at 120/277V AC. That is a full standard commercial lighting branch circuit, so a single pack typically handles the fixtures on one 20A circuit. If your sensor zone spans more than one circuit, you need a power pack per circuit rather than daisy-chaining the load through one unit.
3) Does the OPP20-D1 support manual-on (vacancy) operation for energy code compliance?
Yes. The OPP20-D1 is an Auto ON / Manual ON pack, so you can run it fully automatic (lights come on when the space is occupied) or as manual-on / auto-off, where the occupant switches the lights on and the sensor turns them off. The manual-on sequence is the one commonly required where a vacancy-style control is specified.
4) What is a power pack for in an occupancy sensor lighting system?
A power pack is the piece that does the actual switching. Low voltage occupancy or vacancy sensors don't carry line current; they send a signal, and the pack supplies low voltage power to the sensor and switches the 120V or 277V load. The Leviton OPP20-D1 fills that role at 20A, letting you add sensor control to an existing circuit without replacing the fixtures or the wall switch gear.
5) Can I use the Leviton OPP20-D1 on a retrofit, or is it for new construction only?
Both. The OPP20-D1 is a standard power pack intended for adding occupancy and vacancy sensor control to new or existing lighting circuits, and Leviton lists it for offices, retail, warehouses, industrial spaces and schools. On a retrofit you are adding the pack at the fixture or junction box and running low voltage to the sensor, rather than rewiring the circuit.
6) Is the OPP20-D1 a dimming pack or a simple on/off switching pack?
It is a standard switching pack, not a dimming control. The OPP20-D1 handles on/off switching of a 20A, 120/277V lighting load under sensor command. If your specification calls for 0-10V dimming or daylight harvesting, you need a dimming-capable pack instead.
7) What color is the Leviton OPP20-D1 housing?
Gray. It is a utility housing that mounts at a junction box or in the ceiling plenum, so the finish rarely shows in the occupied space, but if you are standardizing a building's control hardware every OPP20-D1 comes in the same gray.
