Terminate Load Connections - GMT Fuses
Single-Slot Distribution
When using 20 A fuses adjacent fuse positions must be left open. No more than 80A may be carried
through the 10 fuse positions, or 40A per half-section. Up to 14 AWG wire can be used to connect loads
to each of the fuse positions. See Figure 5-21 for fuse position and terminal block designations.
Double-Slot Distribution
The 16 GMT fuse position terminal blocks will accommodate 10 AWG wire. Each fuse board (A and B) has
8 GMT positions and is sized to handle up to 80A of total current and can support up to four 20 amp
fuses if spaced properly. If 20A fuses are used, then adjacent fuse positions must be left empty. See
Figure 5-22 for fuse position and terminal block designations.
