Fuses/Circuit Breakers Specifications; R/V Model Fuses - GMC G Service Manual

FUSES/CIRCUIT BREAKERS SPECIFICATIONS

The wiring circuits are protected from short circuits by a combination of fuses, circuit breakers, and fusible thermal links in
the wiring itself. This greatly reduces the hazard of electrically caused fires in the vehicles.
Replacement fuses must be of the same amperage as the burned-out fuse. Refer to the following charts for the amp ratings
of the various fuses and related components.
