Application
The 104SPP is useful when a boat equipped with a 30A 125V shore-power inlet needs to connect to an available 15A 125V straight-blade power source.
The total electrical load must remain within the rating of the lowest-rated component in the connection. When connected to a 15A source, the available load is therefore limited by the 15A supply.
