Multiple RTS Switches
 You may run into a situation where you need to switch two panels from a single generator. You can
run two RTSY/T/W/R/P/C switches together with no additional equipment. On rare occasions you may
need more than two switches.
 If two RTSY/T/W or RTSR/P/C switches are required: The 1st switch is wired normally. This will be the
switch that sends N1, N1 and T1 120VAC to the generator. The second switch will have only 23,
194/15B, and 0 wires.
 If more than 2 switches are required, you'll need to add a relay to the first switch. There are several
different versions of how to do this; call us for help if you need more than two switches.
Failure to add the Relay Circuit for 3 or more switches, will result in permanent damage to the Generator
Controller.
Important Note: A maximum of Ten (10) Transfers Switches can be used in this configuration.
This added Relay Circuit will work with all single and 3 phase RTS Style Switches.
