A method and apparatus for providing electrical protection for circuits that use splice connections between a source of electrical power and wires of respective circuits (31, 32). The splices provide a common connection of wires to the power source. The splice includes a positive temperature coefficient means (22, 24) in electrical series between the power source and the wires (33). The positive temperature coefficient means (22, 24) reduces the flow of current to the wires (33), and to any loads (31, 32) connected to the wires, when an excess amount of current flows through at least one of the wires and the splice. The temperature rise in the positive temperature coefficient means reaches a trip point, and the means remains in a trip state until power fed to the splice is removed.
