Thinner cables can be used to connect the control switch to the relay thereby saving weight, space and cost. 2. Relays allow power to be routed to a device over the shortest distance, thereby reducing voltage loss. 3. Heavy gauge cable only needs to be used to connect a power source (via the relay) to the device.Introduction. In layman's terms, a relay is an electromagnetic switch that is typically used to switch the power supply either automatically or manually.In this post, I'll go over the fundamentals of 4 and 5 pin relay wiring diagrams.The relay comes in a variety of shapes and sizes. It can be based on the pins or contacts, ampers, or voltage ratting (AC or DC).

Capacitor is known to be good and wired with fan brown lead to FAN and fan purple lead to HERM. Capacitor common is L1. Black fan wire is connected to black side of the contactor - L2. In this configuration the fan runs counter-clockwise shaft-up. When polarity is reversed and improper to the fan wiring diagram, fan runs clockwise shaft-up.If you want to pick a speed wire as below. Power comes to the switch from the fuse panel via the #14 Brown wire.
