-====== Relays ======
-Electrical relays are devices used to **turn relatively heavy loads on/off**.  They are triggered by small amounts of power from an external source (usually a switch operated by the user) but can pass larger amounts of power to the load.
-switch (and house power) --> relay --> load
-The most common relay is the solenoid that campers use to [[electrical:12v:alternator|charge house batteries from the coach's alternator]].  They are also useful for powering loads from [[electrical:12v:lvd|LVD]] or [[electrical:solar:charge_controller|Charge Controller]] LOAD outputs.
