We are protecting against a defective fuse such as Paul had or a direct
short in one of the lines that has blown a good fuse. The other line will
continue to operate the EC2 if you have diodes to prevent a backfeed. Of
course you wish to separate the wires to prevent the burning one from
destroying the 2nd one.
