Wire sizes based on recommendations of the American National
Standards Institute (ANSI) approved National Fire Protection
Association's (NFPA) National Electrical Code (NEC). Table
310-16 for copper wire at 90°C conductor temperature, operating
in ambient of 30°C was used. For other operating ambient
temperatures, refer to the NEC. For operation in countries
where the NEC is not recognized, follow applicable codes.

2

Wire sizes listed are sufficient to restrict voltage drop to 1.0 volt

or less at rated full load output current for the loop lengths
shown. Loop length is the sum of the lengths of the positive and
negative leads.

Two-hole lug, 1/4" bolt clearance hole, 5/8" centers. Refer to

drawing 031110100 for lug crimping information.

DC Output (-48V)

Features

♦ Two (2) 6-position 0A to 15A GMT Fuse Modules (for a total of 12 fuse positions) are provided for load

distribution.

♦ Load and load return leads are connected to a screw-type terminal block located on the front of each

GMT Fuse Module.

♦ Each GMT Fuse Module is equipped with six (6) dummy fuses and safety fuse covers.

Restrictions

The rating of the distribution device determines the wire size requirements. Refer to the American National
Standards Institute (ANSI) approved National Fire Protection Association's (NFPA) National Electrical Code
(NEC) and applicable local codes.

When used for power distribution, load should not exceed 80% of device rating, except 10 and 15 ampere
fuses, for which load should not exceed 70% of device rating.

Terminal block wire size capacity is 24 to 14 AWG.
Each GMT Fuse Module has a 30A @ +65°C (+149°F) maximum capacity (combined load of both GMT Fuse

Modules must not exceed shelf rating of 30A). Maximum GMT fuse size is 15A. Fuses are to be loaded from
bottom of the shelf to top of the shelf with highest value in the lowest position.

Caution: A fuse with a rating greater than 10 amperes SHALL HAVE an empty mounting position

between it and any other overcurrent protective device.
