In-line fuse with switch

[adonh]

Quick question. Does the inline fuse go between the switch and the power source or between the switch and the load.

It depends. The in-line fuse for a electric hitch jack goes between the battery and the switch while the fuse for the water pump is between the switch and the pump. I would think that between the switch and the load would be better location in most cases. It would allow you to replace the fuse with the power removed from the wires. In the case of the jack, the switch is built into the device.

the closer the fuse it to the source, the more wire it protects. example: if you put the fuse at the jack, if the wire before it shorts, there will be no protection for that. if you want to overdo things put a higher rated fuse at the beginning at the wire and a lower rated fuse near the jack, the lower one SHOULD always blow first when protecting the jack.
