5.6.2 Distribution cabling
Refer to the guidelines supplied with the load equipment. Distribution cables are typically sized to provide a 0.5V
loop drop at full load as well as meeting ampacity requirements of the protection fuse or circuit breaker. Terminate
the distribution cables to the distribution center with ¼"–5/8"C lugs.
5.6.3 Breaker output (hot) connections
Connect the breaker output (hot) cables before connecting the breaker return (ground) cables. Secure the two
hole lugs to the ¼" studs (on 5/8" centers) using the hardware supplied with the distribution center. Run the
cables directly out of the rear of the distribution center. Refer to Figure 10.
5.6.4 Breaker return (ground) connections
Connect the breaker return (ground) cables o the distribution center ground bar. Secure the two hole lugs to the
¼" studs (on 5/8" centers) using the hardware supplied with the distribution center. Run the cables directly out of
the rear of the distribution center above the breaker output (hot) cables.
5.6.5 Battery breaker connections
Connect the battery breaker (hot) connections first using the same guidelines as the load cable installation.
Connect the battery ground cables using the same guidelines as the load return cables. The cables should run
directly out of the rear of the distribution center above the breaker output (hot) cables.
