In the 2000 Franklin Electric AIM Manual, we have included Circuit Breaker and Fuse Sizing for our submersible motors (Tables 13, 21, 22, and 23). You should note that the values listed in the AIM Manual are the maximum allowable values per the National Electrical Code (NEC) and that fuse and circuit breaker sizes should never exceed these values. However, smaller, more conservative breaker/fuse sizes are typically used in submersible applications. These smaller sizes, along with the NEC maximum sizes, are listed in the tables in the AIM Manual
Remember, either size will protect the circuit, but never exceed the maximum NEC value.
