    Frequently Asked Questions
    Question

    What is the EPCO Illumination Control Fixture Whip (ICFW) used for?

    Answer

    The ICFW is a pre-fabricated solution for illumination and lighting control, designed for LED and fluorescent systems in commercial, industrial, and institutional buildings across the U.S. It supports daylight harvesting, occupancy sensors, timed schedules, and wireless lighting controls.

    Question

    What voltage systems does this fixture whip support?

    Answer

    The ICFW is compatible with 120/277 VAC lighting systems.

    Question

    Is this product UL and NEC compliant?

    Answer

    Yes. The ICFW is UL Listed (File #E87199) and meets 2026 NEC Articles 300.3(C)(1), 725.136(I)(1), 725.139(A-D)(1), and California Title 24 Lighting Controls requirements.

    Question

    Can it combine multiple circuits in the same whip?

    Answer

    Yes. The ICFW supports Class 1, Class 2, and Class 3 circuits within a single fixture whip, allowing combined power and control wiring in one pre-fabricated assembly.

    Question

    How does the ICFW differ from EPCO’s standard fixture whip?

    Answer

    The standard whip connects only line voltage conductors (Class 1). The ICFW includes low-voltage conductors for dimmable ballasts, LED drivers, and wireless lighting controls, enabling a single pre-fabricated whip for smart building applications.

    Question

    Can the ICFW be used for retrofit projects?

    Answer

    The pre-fabricated design reduces labor, installation errors, and on-site wiring complexity, providing a cost-effective, reliable solution for contractors and facility managers.

    Question

    Are custom options available?

    Answer

    Yes. EPCO can provide custom lengths, wire gauges, and connector configurations to meet project-specific requirements.

    Question

    Do wireless lighting controls require a special fixture whip, and if so, why?

    Answer
    • Wireless Lighting Controls use Relay Modules that can be attached to the outside of an electrical junction box with a nipple.
    • The connection(s) of the low voltage conductors from the dimmable ballast or LED driver are intended to go through the Junction Box, and through the nipple and into the Lighting Control Relay Module to receive controller commands.
    • When the Electrical Contractor wants to use a single pre-fabricated Fixture Whip to control a luminaire with control features.
