T&T Power Group supplies the industry's best TRANSFER SWITCHES.



The Brains of Your Standby Power System.

ATS's are the motherboard behind your generator system.  This switch continuously monitors the power coming from your utility. When the power goes out, the ATS automatically transfers power from the utility to your generator. When utility power is restored, the ATS turns off your generator and transfers back to power from the utility grid. Whether you have standby power for your staff, security or customers, you have the peace of mind that you will always have the energy they need.
