A simplified drawing shows the front face of the VU. Each circuit breaker head is marked with the FIN and not with the rating. This is to help to identify circuit breakers when they are opened during aircraft maintenance procedures.
NOTE : On the aircraft, the FIN is shown on the rear side of the
____
VU panel.

B. Configuration of Circuit Breakers
(1)
Black head circuit breaker This type of circuit breaker does not have an auxiliary contact. It is standard.
(2)
Green head circuit breaker This type of circuit breaker holds an auxiliary contact connected to SDAC when it is tripped.
(3)
Circuit breaker with a red threaded bush For safety reasons, to avoid that the crew resets it in flight, the C/B is guarded. If it is necessary to open it, the red threaded bush must first be removed, unscrewed with a standard wrench.
(4)
Circuit breaker with a yellow collar Some circuit breakers have a yellow collar to help the crew to find them more easily on the circuit breaker panel.
(5)
For clipped circuit breaker, there are two types of collars, metallic or plastic, secured by lockwire, (Ref. ESPM 20-46-10).
