Three types of transfer switches are available for transferring electrical loads between power sources.
Automatic Transfer Switches (ATSs)
Monitor power conditions and transfer between sources, as needed, without human intervention.
Non-automatic Transfer Switches (NTSs)
Transfer loads to an alternate source when prompted by an operator through electrical controls.
Manual Transfer Switches (MTSs)
Require someone to manually transfer loads using external operating handles on the equipment.
