Chapter 3: Installation Procedure
Connecting Conductors from Source Circuits
Source circuits refer to output from PV arrays through the combiner to the BUSS.
1. Label each wire from the source circuit with a reference number and its
polarity.
2. Run all ungrounded wires, grounded wires, and the equipment ground
conductor into the Breaker Universal Safety System enclosure through the
selected entry point.
3. Connect all ungrounded inputs on the corresponding circuit breaker input in
order by labeled circuit breaker (
). If there are fewer connections to
be made than there are circuit breakers in the unit, populate the
lower-numbered circuit breakers first.
