GridBOSS BSB 50A AC Circuit Breaker for 12KPV — Product Summary The GridBOSS BSB 50A AC Circuit Breaker is a purpose-built AC protection device designed for use with the EG4 12KPV hybrid inverter when integrated into a GridBOSS power distribution or backup panel. Its primary function is to provide reliable overcurrent and short-circuit protection for the inverter’s AC output feed, safeguarding both the inverter and the connected electrical system in residential and light commercial solar storage installations. Key Features Correctly Sized Protection Rated Current: 50 amps — matched to the nominal AC output capacity of the 12KPV inverter when paired with a GridBOSS distribution configuration. Safety & Compliance Designed to meet applicable electrical safety standards for residential AC protection. Helps satisfy NEC (National Electrical Code) requirements regarding overcurrent protection for inverter output circuits. Trip-Free Operation Automatically disconnects under overload or short-circuit conditions, even if the breaker handle is held in the on position, ensuring safer, system-protective behavior. AC System Compatibility Intended for 120/240 VAC split-phase systems, typical of U.S. residential electrical service and whole-home backup configurations. Installation-Ready Fits standard breaker panels or GridBOSS distribution enclosures where a 50 A breaker is specified for inverter output protection.
