Distribution guidelines
•
A Power system can have three tiers of distribution: Tiers 1, 2, and 3.
•
When adding distribution groups, tier 1 is factory installed (group A & B) with AM1 capability start at tier 2 upwards.
•
AM1 type breaker distribution can be located in any group.
•
GJ1 type breaker distribution must be installed as the topmost group, above all other distribution types.
•
As distribution is added, additional return bus sections (up to 3 total) may be needed to provide terminations (landings) for
load returns. See Figure 7-3. Order the return bus sections separately as needed.
