Circuit Breaker(B)
The panel board is installed under the left floor step.
REMARK
This circuit breaker is a large-size breaker installed to circuits
where a large-capacity current is flowing. In the same way as
normal fuses and circuit breakers installed to the power board
inside the cab base room, this circuit breaker protects the elec-
trical components and wiring from burning out if there is a
surge of current.
