Q: What is the difference between the Generac Nexus Smart Switch (100 Amp) automatic transfer switch for $349 and the Generac Nexus Smart Switch (100 Amp) automatic transfer switch (Service Entrance) for $499?

Thank you for your time and consideration.
by Cecil Camune from Illinois on January 29, 2011

A: The "Service Entrance" type automatic transfer switch has a built in shut off switch to power can be turned off to perform service on the generator without backlash from utility power. This type of switch is normally required by code to be installed if used in a whole house application and mounted between the meter and electrical panel being powered.

The "Standard" type automatic transfer switch does not include this service entrance feature and is normally installed when the generator is powering a sub-panel.
