Standby Generator Costs
A standby generator is in place to pick up the power demand when a grid outage occurs, thereby providing backup power automatically when needed.
You will find that the cost to install an average standby generator depends upon the power and class ratings, power transfer controls, job preparation and special requirements, and the labor rate.
In the following table the Labor Cost figure is what the able and prepared DIY persons should expect to save by performing the corresponding tasks.
