panel. These switches receive power from the Accessory bus. Switches 1 – 3 are fused by separate 15A circuit protection
devices (fuse or circuit breaker). The location of these circuit protection devices are labeled on the central electrical panel
cover. For example “SPARE ACC SWITCH #1” is the label for spare switch #1.
