Simple 15A Shore Power In Small Boat (Looking to install in-line 15A AC Breaker )

[NS22Wren]

My Nonsuch 22 has a simple DC panel and no AC panel. The marina I am in has 30A shore power connections. I would like to use a 30A (male) X 15A(female) adapter to supply my battery charger via a commercial grade temp power cord with a GFCI similar to Levition's 69591-W25. I would like to install an in-line breaker after the 30AX15A adapter since the rest of the system is sized for 15A. Does anyone know of a suppiler of 15A in-line breakers that can be used installed in a temp power cord?

Thanks!
Nonsuch 22 "Simple"
