Type of Generator Transfer Switch

An automatic generator switch is more expensive than a manual switch. Here’s how the two compare:

Amp Requirements

As the amp requirement increases, the cost of the generator transfer switch will also rise. That’s because higher-amperage switches use stronger parts and better materials to safely handle the extra electricity, which makes them more expensive to manufacture.

How Angi Gets Its Local Cost Data 

To help homeowners plan their next project, Angi provides readers with carefully researched cost data and upholds strict editorial standards. We start with national average project costs, which we collect by analyzing competitor information, retailer material costs, and input from professional contractors. We then apply local price index data to calculate location-specific estimates that reflect what homeowners typically pay in their local area. To do that, we use data from the U.S. Bureau of Economic Analysis (BEA), including its Regional Price Parities (RPPs), which measure price differences across cities. This helps us account for differences in labor, materials, and overall cost of living, so estimates in higher- or lower-cost areas better reflect real-world local pricing.

Every estimate undergoes a thorough editorial review to verify accuracy, consistency, and alignment with observed market conditions.
