National Cathode Logo

120V or 277V

Per ANSI / IES RP-16-10


Power Supply:
To be Power Factor corrected and dimmable, operating at 100MA on T8 (one inch diameter) long life cold cathode lamps. Each power supply to be encapsulated within an approved enclosure and maintained within the cove that is accessible and ventilated (not exceeding 100° F ambient).
Lamp Holders:
To be “RB”, “RRB”, “CIB” or “SE” series per the specifier. Provide right-angle electrodes or staggered straight electrodes for a continuous line of light, with lamp supports for all curved and bent lamps. Circuit interrupting lampholders must be used per the N.E.C. where applicable.
Shall be 25MM Diameter, closed-loop, lead free and triphosphor coated. (300 Lumens per foot).
Wiring / Conduit:
GTO cable will be supplied by N.C.C. and installed by the installing contractor per N.C.C. submitted C.A.D. drawings. Conduit is to be supplied by the installing contractor.

Note: U.L., N.E.C. and the N.B.C. will not accept any cold cathode system with exposed PVC Cable when used adjacent to air handling vents in the coves.

Shop Drawings:
Shall be CAD generated and be submitted for approval and future maintenance. Drawings shall show lighting layout, method of installation, and a complete bill of materials. Installing contractor is responsible for furnishing “As Built” dimensions or full-sized patterns, as requested on shop drawings. This lighting system must comply with ANSI / IES RP-16-10 and C-U.L.-us or be rejected.
