Cooper Bussmann BP/SA-15 Type S Fuse Adapter 15A 3 Pack

Product Description

The COOPER BUSSMANN BP/SA-15 is a Type S fuse adapter rated at 15 amps, sold in a 3-pack. Type S adapters are designed to be inserted into standard Edison-base fuse sockets, converting them to tamper-resistant Type S rejection sockets that accept only the matching amperage Type S fuse. This prevents overfusing, a common code compliance issue in older residential panels and subpanels. The adapter measures 1.83 inches long by 0.917 inches wide by 0.417 inches high and weighs 0.56 pounds per packaged unit. Electricians and qualified DIYers working on older residential wiring rely on this adapter to bring fuse panels into closer alignment with current electrical safety practices.

This adapter is used in residential applications where screw-in fuse panels remain in service. It is most commonly installed in older homes that have not been upgraded to a circuit breaker panel. Once installed, the Type S socket accepts only a 15-amp Type S fuse, eliminating the risk of a homeowner substituting a higher-rated fuse than the circuit wiring can safely carry. The carded 3-pack format is practical for service calls where multiple circuits need to be converted in a single visit.

Installation Notes

Installation should be performed by a licensed electrician or qualified technician in accordance with NFPA 70 (National Electrical Code) requirements for fuse panel service. Always shut off power to the panel or isolate the individual fuse circuit before handling fuse socket hardware. The adapter threads into the Edison-base socket and is intended to be a permanent, non-removable installation once seated. Do not force the adapter into a socket that shows signs of damage, corrosion, or heat discoloration.
