Art. 1065.01 Protective Devices LIGHTING SECTION 1064. RESERVED SECTION 1065. PROTECTIVE DEVICES
1065.01 Fuseholders and Fuses. Fuseholders and fuses shall be as follows.
a.Fuseholders.
1.General. Each fuseholder shall consist of a two-section unit designed to hold small-dimension cylindrical fuses of the type required. Each section shall be permanently marked with line and load side designations and the unit shall have a water and vapor-tight seal when the sections are joined. Two pole quick disconnect fuseholders shall be used unless otherwise specified. The terminals and the contacts in the fuseholder shall be made of tinned copper or other material suitable for contacts as approved by the Engineer. The contacts shall be spring loaded or tulip style to exert contact pressure on mating parts. Fuse holders shall be rated for 30 A at 600 V at 167 °F (75 °C) operation.
2.Fuseholder Material. Fuseholders shall have a molded plastic, neoprene rubber, or impact resistant polymer housing. Wires shall attach to the fuse holder by a crimping operation, except that connection of No. 2 wires to breakaway fuse holder receptacles may be via a set screw connection. Each fuse holder shall be of a size proper for the wires to be attached. The assembly shall be provided with insulating boots as needed.
3.Fuseholder Design. Phase to phase circuit applications shall be designed so that both phase conductors are disconnected at the same time. Phase to neutral circuit applications shall be designed so that both phase and neutral conductors are disconnected at the same time. Blanks shall be used instead of fuses for the neutral conductor and they shall be clearly marked with white bands to designate a neutral plug.
4.Fuseholder Operation. The fuseholder shall be capable of disconnecting upon sufficient tension in the connected wires, as in a pole knockdown. The fuse shall remain enclosed in the de-energized portion of the fuseholder upon disconnection. The fuse shall not be utilized as the disconnection means.
b.Fuses. Fuses for installation within fuse holders for protection of luminaires shall be small-dimension, 1 1/2 in. x 13/32 in. (38 mm x 10 mm), cylindrical fuses of the time-delay type. The fuses shall be rated for 500 V AC and meet the requirements of UL 248-14. The fuses shall have a listed interrupting rating of not less than 10,000 rms symmetrical amperes at rated
