Note: Most companies say not to use an automatic transfer switch with manual portable generators.
Price Range
The price of a transfer switch depends on the kind, your house size, and where you live. Automatic transfer switches cost more than manual ones. Here is a table with common prices:
| Switch Type | Unit Price Range | Total Installation Cost Range |
|---|---|---|
| Automatic Transfer Switch | $400 – $2,000 | $600 – $2,500 |

Choosing the Right ATS
Sizing
You need your automatic transfer switch for household generator to fit your home’s power needs. Picking the right size keeps your system safe and working well. First, check your main breaker’s amperage. The transfer switch should have the same or a higher amperage rating. For example, if your main panel is 200 amps, you need a 200-amp switch. Never use a 100-amp switch with a 150-amp or 200-amp panel.
Here is a table to help you pick the right switch:
| Requirement Aspect | Explanation |
|---|---|
| Amperage Rating | Match or go above your main breaker’s rating. |
| Voltage Requirement | Use a switch with the same voltage as your house, usually 240V single-phase. |
| Service Entrance Rating | Make sure the switch has this rating or use a main disconnect if your panel does not have one. |
| Installation Environment | Pick NEMA 1 for inside or NEMA 3R for outside or wet places. |
| Power Management | If you have many big appliances, choose a switch with load management to stop overloads. |
Tip: Always look at your home’s electrical panel before you buy a transfer switch.
