Q: What is the purpose of a relay?

A: The idea of a relay is that you can run a very thin gauge wire for the switched circuit (off the ignition usually) a long distance to the relay. The power wires can be kept short as large gauge wire costs more and it doesn’t make sense to run 20 feet of 8 gauge wire if you don’t have to!
