Why a switch or fuse shouldn’t be used on the output wires

On occasion, a switch or fuse may be installed in series with one or both output wires as an added safety mechanism. However, this can cause a serious problem if the remote sense lines remain connected to the load.

Why?

Because if the output cable switch or fuse opens, current will flow in the sense lines and cause the internal Rsense resistors to burn up.

System debugging can cause similar problems; for example, where the power and sense cables are located on separate connectors and if by error, only the power cable connector is disconnected.
