Intermatic K4236C – Frequently Asked Questions

1) Will the Intermatic K4236C photocontrol work on a 277V parking lot lighting circuit?
Yes. The K4236C thermal photocontrol is rated 120-277 VAC at 50/60 Hz, so the same unit covers 120V residential security lighting and 277V commercial or parking lot circuits. You do not need to stock separate voltage versions for a mixed site.
2) What thread does the Intermatic K4236C swivel stem photocontrol use for mounting?
The stem is 1/2"-14 NPSM threaded, which is the standard stem thread on outdoor fixture housings and lamp posts. The swivel lets you aim the photocell away from the lamp or oncoming light after the stem is tight, so you are not fighting the thread position to get the sensor pointed north.
3) Is the Intermatic K4236C a stem-mount or a twist-lock photocontrol?
Stem mount, not twist-lock. It threads in on a 1/2"-14 NPSM stem with a swivel arm, gasket and locknut. If the fixture has a three-prong NEMA twist-lock receptacle on the top, this is the wrong body style and you need a locking-type photocontrol instead.
4) Does the Intermatic K4236C photocontrol come with a gasket and locknut, or do I need to buy them separately?
A washer gasket and locking nut ship with the K4236C, and it has #18 AWG 6 inch wire leads already attached. You only need wire connectors and whatever fitting the fixture requires, not a separate mounting kit.
5) Why does a photocontrol need a delay feature for street and pathway lighting?
Headlights, a passing truck's work lamp, or light bleed from an adjacent fixture can fool a photocell into switching the lamp OFF at night. The delay feature on this thermal photocontrol ignores those brief light hits so the fixture stays on until real daylight arrives. On parking lots and roadways where vehicles sweep the sensor all night, that is the difference between steady lighting and nuisance cycling.
6) Thermal bimetal versus electronic photocontrol: which should I use on exterior building lights?
This Intermatic unit is the thermal type, a mechanical bimetal switch triggered by a cadmium sulfide photocell. There are no electronic switching components in the signal path, which is why these are still specified for straightforward on/off exterior lighting. Electronic photocontrols are the choice when you want tighter turn-on levels or very fast response; a thermal unit's slower, built-in delay is an advantage where passing light sources would otherwise cause nuisance switching.
7) How much clearance do I need to fit the Intermatic K4236C photocontrol inside a fixture housing?
Plan for roughly 5 inches of height and 1.563 inches in both width and depth. The slim body clears most pole-top and wall-pack housings, but measure the swivel's arc before you commit if the stem hole is tight against the housing wall.
8) Can I use one photocontrol model across landscape, wall pack, and pole lighting on the same property?
Yes, that is the point of the 120-277 VAC range on the K4236C. It is built for outdoor lighting control generally, so landscape and architectural lighting, building exteriors, perimeter lighting, and pole-mounted area lighting can all run the same part number, provided each fixture takes a 1/2"-14 NPSM stem. Standardizing on one unit cuts the spares you carry.
9) Will the housing on this Intermatic photocontrol hold up mounted in full sun on a south-facing wall?
The housing is high strength plastic with UV resistance, built for prolonged outdoor exposure, and it is grey, which is the standard color for matching the rest of a lighting fleet. For property managers standardizing across many exterior fixtures, it keeps the look consistent and avoids the chalking you get from non-UV-stabilized plastic.
