CIRCUIT BREAKER (CB) PANELS
A circuit breaker panel is installed in the overhead console: it houses all the
circuit breakers available in the cockpit for standard and most common
optional systems connected to the aircraft distribution bus bars.
An optional additional circuit breaker panel is installed when dedicated
optional systems are installed.
CIRCUIT BREAKER (CB) PANEL ARRANGEMENT
The CB panel is divided in two groups of circuit breakers:
• LH group includes CB connected to Essential, Main and Non Essential
bus bars no.1
• RH group includes the CB connected to Essential, Main and Non
Essential bus bars no.2 and Battery Bus
The ESS BUS TIE circuit breaker — rated 50 A — keeps ESS BUS 1 and
ESS BUS 2 interconnected.
ELECTRICAL SYSTEM CONTROL PANEL
All the switches that control the electrical power system are installed in the
forward area of the overhead console.
