Factory-Installed Breakers
Although labeling displaying an amperage rating is present on the factory-installed breakers, they are
intended to be used as a service disconnect only. The factory-installed breaker-style service
disconnect is not intended to be used as an over-current protection device. The electrical information
included on the data plate is used to properly size separate service breakers (i.e. in the electrical
breaker panel), and the electrical conductor. The data plate does not apply to the included breaker-
style service disconnect.
