Utility safety: The National Electrical Manufacturers Association (NEMA) published ANSI C136.14-2014 American National Standard for Roadway and Area Lighting Equipment -- Elliptically Shaped, Enclosed Side-mounted Luminaires. This standard is useful to roadway and area lighting manufacturers, municipalities, utilities.
ANSI C136.14 was developed by ANSI Accredited Standards Committee (ASC) 136. Revisions include added requirements for light sources other than high-intensity discharge (HID), updated references, updated language to reflect committee preference, and added requirements for ingress protection.
This standard covers dimensional, maintenance, and light distribution features that permit the interchange of enclosed, side-mounted luminaires for horizontal-burning HID lamps and other light sources used in roadway and area lighting equipment. This type of luminaire has traditionally been used for street or roadway lighting, and has commonly been referred to as “cobrahead” style luminaires.
Luminaires of similar size, shape, and weight meeting the requirements of this standard may be used interchangeably within a system with assurance that (1) they will fit the bracket arm, (2) pole strength requirements will not change, (3) light distribution will be similar, and (4) similar maintenance procedures can be used.
Historically, luminaires covered by this standard are elliptical in shape with lenses that meet the requirements of ANSI C136.17. Luminaires other than HID may have a different, unique shape as long as they meet the requirements listed above.
Excluded from this standard are luminaries having rectilinear and round shapes.
