DC Service Switch
CRJ200 - Electrical Power Service Panel - DC Service Switch
Controls power to the DC Service Bus which in turn supplies electrical power for lighting in the passenger cabin and for the external navigation lights. It is normally power by the SERV TRU.
In all my time flying the CRJ200, I have never had any instance that I have had to use this switch, so chances are that I will probably never have to either. Most stations or FBO’s will have AC Power which will do the same thing…and more. In fact, I would be very surprised if you could even find a source of DC power these days.
Note: The BATTERY MASTER SWITCH does not have to be on to use DC power.
When the switch is selected ON, the DC Service Bus is powered.
When selected OFF, the DC Service Bus is not powered.
Hope that helps!
To your flying success,
Jeffrey
