A barge fuse is a protective device located on the incoming service line. Its purpose is to cut power if a fault occurs so the property remains protected from electrical hazards. It prevents damage to wiring, appliances and switchboards by isolating high fault currents.
Common reasons for barge fuse replacement include:
- Blown fuses caused by faults or overloads
- Deterioration due to age or heat exposure
- Damage from storms, falling branches or water ingress
- Incorrect or unsafe fittings installed by previous contractors
- Replacement required during service line upgrades
- Faults caused by old or undersized consumer mains
Because the barge fuse sits on network-controlled supply it must be handled only by Level 2 Accredited Service Providers.
