O & M Manual for the 50-400A EGSX Transfer Switch Instruction Booklet IB 70-8778 Effective November 2011 1.2 General Information 1.2.1 Design Configuration TSs are used to protect critical electrical loads against loss of power. The load’s utility power source is backed up by a generator power source. A TS is connected to both the utility and generator power sources and supplies the load with power from one of these two sources.
O & M Manual for the 50-400A EGSX Transfer Switch Instruction Booklet IB 70-8778 Effective November 2011 The benefits of the SE configuration are: • Combined service disconnect and over-current protection in the TS reduces the overall equipment and installation costs. • Fewer components and power connections reduce maintenance requirements. 1.
O & M Manual for the 50-400A EGSX Transfer Switch Generator Generator is the secondary source (generator emergency source, emergency power source, emergency, standby, or backup source). Utility: Failed or Fails Utility is defined as “failed” when it is outside of its undervoltage setpoint ranges for the nominal voltage and frequency setting.
