How to Combine a Standby Generator and Transfer Switch

By 
 | 
Generator Product Expert

So now... You should know how many amps come into your electrical panel.

You should also know how many kilowatts your standby generator needs to start your central air conditioner.

And, finally, you should have a basic grasp of the different automatic transfer systems available.

Now, we just need to blend all three together.

To make things simple, use the chart below to pick a home standby generator system.

For example, you have 200-amp service and want to power your central air conditioner and mission critical appliances, we recommend:

Standby Generator = Generac Guardian 20kW
Automatic Transfer Switch = 200A Service Entrance + AC Shedding
