Intermatic LC4523 – Frequently Asked Questions

1) Does the LC4523 fit the twist-lock receptacle already on my pole-mounted fixture?
If the fixture has an ANSI C136.10 NEMA photocontrol receptacle, yes. The LC4523 uses a locking type plug base that twists into that standard receptacle, which is the socket found on most street, roadway and area light heads. No wiring is needed at the fixture, so swapping a failed control is a plug and turn job.
2) Does the LC4523 meet ANSI C136.10 for photocontrol interchangeability?
Yes, it is built to ANSI C136.10, the standard that governs locking-type photocontrol and receptacle compatibility. That is what lets it drop into any fixture already fitted with a C136.10 receptacle regardless of the luminaire brand.
3) Is the LC4523 a thermal (bimetal) photocontrol or an electronic one, and does that matter?
It is a mechanical bimetal thermal type using a cadmium sulfide photocell. The bimetal switch gives thermal protection and keeps switching dependable across temperature swings, and the built-in delay stops nuisance OFF switching from passing headlights or lightning. Electronic solid-state controls switch faster and silently; a thermal control like this one is the long-standing choice for street and area lighting where ride-through on brief light flashes is what you want.
4) Can I mount the Intermatic LC4523 photocontrol outdoors with no extra enclosure?
Yes. The housing is integral high impact thermoplastic built for weather and mechanical protection outdoors, which is where this control is meant to be used for dusk-to-dawn lighting control. It mounts on the fixture itself through the receptacle, so no separate box is required.
5) How much vertical clearance do I need above the fixture receptacle for this photocontrol?
Allow at least 2.75 inches of clearance. That is the stated height of the LC4523 body above the twist-lock base, which matters when the head sits under a shroud, a decorative cap or a tight canopy.
6) My other poles have Intermatic photocontrols with a maroon band. Is the LC4523 the same one?
The LC4523 is white with a maroon band, which on Intermatic locking photocontrols identifies the 208-277V group. If the existing controls on your other poles carry that same maroon band and the heads are on 208-277V circuits, this is the matching unit for standardizing a site.
7) How many switching cycles has the LC4523 photocontrol been tested to?
3,650 ON/OFF cycles. At one cycle per night that is roughly ten years of dusk-to-dawn duty, which is the figure to quote when a spec calls for cycle-tested photocontrols on a municipal or campus lighting package.
8) What model should I order and where is this Intermatic photocontrol made?
Order Intermatic model LC4523. It is manufactured in Mexico.
