About this file
This is a specification document for electrical fuses issued by Volusia County for the Branch Jail facility located at 1300 Red John Drive, Daytona Beach, Florida. The specification section 262813 details the requirements for cartridge fuses rated 600 V ac and less for use in control circuits, motor-control centers, panelboards, switchboards, enclosed controllers, and enclosed switches, along with spare-fuse cabinets. The fuses specified are NEMA FU 1, current-limiting, nonrenewable cartridge fuses of Type T rated at 250-V with zero- to 1200-A rating and 200 kAIC time delay. Bidders must provide product data including construction details, dimensions, electrical characteristics, current-limitation curves, and time-current coordination curves. Installation requires compliance with NFPA 70 standards, with fuses arranged for readable rating information and installed in fusible devices as indicated in project drawings. Maintenance material submittals require furnishing spare fuses equal to 10 percent of the quantity installed for each size and type, with a minimum of three of each size and type, packaged with protective covering and properly labeled.
The specification requires that all fuses be obtained from a single manufacturer source and that electrical components be listed and labeled by a qualified testing agency. Contractors must examine fuses before installation and reject any that are moisture or physically damaged. Spare-fuse cabinets must be wall-mounted steel units with gray baked enamel finish, featuring full-length recessed piano-hinged doors with key-coded cam locks, and exterior identification marking. All fuses must include labels indicating replacement information adjacent to fuse blocks, sockets, and holders in compliance with Section 260553 for electrical systems identification. Ambient temperature adjustment factors must be applied when fuses are directly exposed to temperatures below 40°F or above 100°F, with supporting manufacturer technical data required as part of operation and maintenance documentation submitted in PDF format.
