NSi 3010 – Frequently Asked Questions
1) Will the NSi 3010 button photocontrol switch LED fixtures, or is it only rated for incandescent?
The NSi 3010 handles all three load types: 2000W tungsten, 1800VA ballast, and 600VA LED at 120V. The LED figure is the one that trips people up, so size your LED pole or pathway fixtures against 600VA and not the 2000W number. Driver-based LED loads draw inrush, so keep total connected LED wattage comfortably under that 600VA ceiling.
2) Can I use the 3010 photocontrol on a 277V circuit?
No. The 3010 is a 120 VAC only device, rated 50-60 Hz. On a 277V branch circuit you need a 277V-rated photocontrol instead. Wiring this one to 277V will destroy it.
3) How does a flush mount button photocontrol install compared to a stem or twist-lock type?
Button-style means it presses through a drilled hole in the fixture housing or canopy, with 9 inch leads hanging inside for splicing to the hot, neutral, and switched load. There's no stem elbow and no twist-lock receptacle involved, so it's the choice when you're retrofitting sensing into an existing pole lantern or landscape fixture that has interior wiring room. If the fixture already has a NEMA twist-lock receptacle on top, you want a locking-type photocontrol instead, not this one.
4) Will this photocontrol hold up outdoors through a northern winter?
Operating range is -40 to +140 F, and the body is a Lexan housing, which is what carries the UV and impact duty on an exposed lantern or walkway fixture. That covers most North American climates year round. The housing still needs to be mounted so the lens faces out and water is not standing against the leads.
5) Why does my photocontrol need a time delay, and what is the delay on the NSi 3010?
The 3010 has a 2 minute timing range. That delay is what keeps headlights, lightning, or a neighboring fixture's own output from cycling the lamp off and back on. For property managers chasing nuisance flickering on pathway lighting, that delay is the spec that fixes it.
6) At what light level does the NSi 3010 turn lights on and off?
Turn-on happens between 1 and 5 footcandles and turn-off between 3 and 15 footcandles, read by a cadmium sulphide cell. That spread between on and off points is deliberate hysteresis so the unit won't hunt at dawn and dusk. In practice lights come up at deep twilight and drop out once full morning light hits the lens, which is why mounting orientation matters: aim the lens away from the controlled lamp and away from any adjacent fixture.
7) Does the photocontrol itself add measurable load to the circuit?
Under 1 watt. On a multi-fixture retrofit across a campus or apartment complex, the sensors themselves are not a load worth calculating into your panel schedule.
8) What kinds of fixtures is the NSi 3010 button photocontrol intended for?
Pole lanterns, lawn and landscape lighting, and walkway or pathway fixtures are the stated applications. It's a dusk-to-dawn switch for small exterior loads on a 120V circuit, not a parking lot or roadway control package.
