Well. Doing what you are doing and putting your money on the great big Wheel in Las vegas..... Have a lot in common.
Good chance you are going home from "Lost Wages" understanding why Los Vegas has that nickname.
There are two possible outcomes.. And it depends on two things
1: how fast the ATS transfers
2: Where in the power cycle it transfers.
The ATS is what is called a "Break before Make" switch this means it does not go from Genny to Shore.. It goes from Genny to OFF to Shore
When it goes to OFF, with big motors like the A/C running, there is something we call an inductive "kick".. Think of Induction like Inertia
As you know an object in motion tends to remain in motion in the same direction unless acted upon by an external force.. A LOT of force in many cases.
LIkewise have you ever shut off a water faucet and heard the pipes "Rattle".
These are both examples of "Inertia" (The water tries to keep flowing, the moving object tries to keep moving)
Electronics are like that. only we call it inductance. They want to keep moving. and what's worse is the motor has a form of inertia so it turns to a generator till it stops.. The result can easily be a thousand volts or more at the ATS Contactors (Solenoid or Relay) and this can jump the gap and weld the contacts closed..
Instant need for a new ATS.
Happened to me.. Thankfully under warranty.
