GENERATOR PROTECTION & DISCONNECT
Because generators are required to be protected only against overloads, the generator and the conductors connected to a downstream protective device do not require short circuit protection.
DESIGN FOR SAFE AND RELIABLE ELECTRICAL
The DC rated Battery Circuit Breaker (BCB) provides still overcurrent protection, if correctly coordinated, even though it is not as fast as the fuses. These breakers must be set at a safe
