3. Installation
Make sure the location satisfied the requirements listed under Storage and Installation
Location (page 3) and check the dimensions using the diagrams in other catalogs or external
view diagrams and panel cut diagram. Prior to installation, the maximum fault current capacity
of the power system at the point of installation should be verified. This value must not exceed
the symmetrical interrupting capability of the circuit breaker. See typical circuit breaker
nameplate below.
Do not exceed the ratings specified on the breaker nameplate or
system accessories. Underrated equipment can fail during operation
causing fire, explosion, severe injury, death, and property damage.
