I wouldn't call a relay a current reducer but rather a current shifter. It'll shift the current from the switch to itself, but it will do nothing to reduce the current the load needs, leaving only the current needed to operate the relay for the switch to handle.



Fair enough. Agreed! I oversimplified as my point was not to lose sight of the importance of wire size as well. I've seen a few times where people were shocked when their "fused" circuit smoked due to burning wire. cry

A relay is a current redirector, a fuse is a circuit fail safe.
