3. Selecting Breakers
● The Span Panel accepts a 100–200 A main breaker and up to 32 branch breakers in the panel for load circuits.
● Install each branch breaker by rocking it down to seat it fully onto the busbar stab and engaging the clips that hold it in
position. Ensure each breaker is firmly in place.
CAUTION: Install only listed and labeled circuit breakers compatible with the Span Panel. Branch circuits must not exceed
the load limits specified below.

* Branch breakers must be series rated with SquareD QOM main breaker to achieve the 22 kA short-circuit current rating.
CAUTION: Use only appropriately sized, compatible circuit breakers according to the type of load. Ensure breaker selection
is in accordance with NEC, CEC, and local code articles for any field modifications. Additional or replacement breakers
should be of the same manufacturer, type designation, and equal or greater interrupting rating.
CAUTION: Refer to the specific breaker location instructions for each grid-forming hybrid inverter in the Storage System
Integration Manual. Hybrid inverter breaker(s) must be connected to the position(s) indicated for the system to operate
as intended.
