Claim 11:
12. A method, comprising:
sensing a first voltage or a first current at an input side of a low voltage DC power distribution system having one or more DC power supplies based on removably electrically connecting a portable testing apparatus to the input side of the one or more DC power supplies;
sensing a second voltage or a second current at an output side of the one or more DC power supplies based on removably electrically connecting the portable testing apparatus to the output side of the one or more DC power supplies;
selecting a fault from a plurality of fault types;
inducing the fault to the output side of the one or more DC power supplies;
comparing a first data of the first voltage or the first current sensing to a second data of the second voltage or the second current sensing; and
determining whether or not the fault has propagated to the input side of the one or more DC power supplies based on comparing the first data and the second data.
