The possibility of decreasing the life of the transfer switch is absolute.
Rv automatic transfer switch not working.
Sustained contact chattering can cause transfer switch damage.
The automatic transfer switch is not working because the screw was cross threaded and now needs to be replaced my extended warrenty will not cover because its a cross thread.
An automatic transfer switch is a three way switch that will switch power between two inputs and connect it into a single output.
Without a schematic or at least a block diagram you re basically flying blind while troubleshooting.
The automatic transfer switch is installed before the breaker panel.
If the voltage level drops far enough the contactor points will chatter.
Contactor based transfer switches are also affected by low voltage.
Turn off the shore power and disable the automatic generator start so no power goes into the xfer switch until someone can check out the wiring that s burnt.
Depending how long it takes to get repaired he may want to go out and purchase a battery charger to keep the house battery voltage up.
The possibility of failure is high.
Switches that have been damaged by chattering need to be returned to the factory for replacement.
I believe this should be a repair that you cover since it came from the factory this way.
The generator shouldn t have a transfer switch but it should have some sort of output circuit breaker.
