Guide Information for Electrical Equipment for Use in Ordinary Locations

402.152603.4.1.122611H106.1.1H107600.24(A)600.3600.8(B)600.8(D)680.57(A)680.57(C)(1)680.57(C)(2)600.24(A)600.3600.8(B)600.8(D)680.57(A)680.57(C)(1)680.57(C)(2)

USE AND INSTALLATION

This category covers signs that are electrically operated and/or illuminated using incandescent lamps, LEDs (light-emitting diodes), electro-luminescent panels, neon tubing, fluorescent lamps, high-intensity-discharge lamps or combinations thereof for installation in accordance with Article 600 of ANSI/NFPA 70, "National Electrical Code" (NEC).

Cord-and-plug-connected signs do not have provision for permanent mounting to a building or structure. Due to servicing considerations, specific types of cord and plug-connected signs are intended and have provision for installation on end-use equipment.

Signs or sections of a sign forming a complete enclosure intended for permanent connection to a source of supply are provided with permanent means for attachment to a building, to a support or to a hanging rig. The mounting hardware, poles and other structural components of a sign have not been evaluated with respect to local variable conditions such as local wind and snow loading or soil conditions.

Electric signs, of such size that shipment in one carton or fully assembled is impractical, may be divided into sections. Each major subassembly bears an "Electric Sign Section" Certification Mark. Sign faces, trim and mounting hardware are not considered major subassemblies. Each sign has installation instructions describing or illustrating the proper assembly, mounting and connection of the sign sections. The acceptability of the assembled sections in the field rests with the Authority Having Jurisdiction.

Signs or sections of a sign, such as gasoline pump toppers, that are intended to derive power from within flammable- or combustible-fuel-dispensing equipment require special investigation to UL 87, "Power-Operated Dispensing Devices for Petroleum Products" (see Retrofit Assemblies (ERKQ)). The acceptability of such electric signs installed on or near fuel-dispensing equipment is subject to the provisions of Article 514 of the NEC, and rests with the Authority Having Jurisdiction.

PRODUCT MARKINGS

All signs are marked to indicate their intended use location using one of the following environmental location markings:

"Dry Locations Only"
"Suitable for Damp Locations"
"Suitable for Wet Locations"

Signs, whether permanently connected or cord-and-plug connected, are only investigated for installation in accordance with their marked environmental location. Signs marked "Dry Locations Only" are only investigated for indoor use.

Signs, sign sections or outline lighting marked "The neon supply(ies) complies(y) with the secondary ground-fault protection requirements of UL 2161" are provided with neon transformers and power supplies that comply with the secondary fault protection requirements specified in UL 2161, "Neon Transformers and Power Supplies."

REBUILT PRODUCTS

This category also covers signs that are rebuilt by the original manufacturer or another party having the necessary facilities, technical knowledge and manufacturing skills. Rebuilt signs are rebuilt to the extent necessary by disassembly and reassembly using new or reconditioned parts. Rebuilt signs are subject to the same requirements as new signs.

PRODUCT IDENTITY

One of the following product identities appears on the product:
