SECTION 1.2

PREPACKAGED INSTALLATION BASICS

POWER SOURCE AND LOAD LINES

The utility power supply lines, the standby (generator) supply lines, and electrical load lines must all be connected to the proper terminal lugs in the transfer switch. The following rules apply:In 1-phase systems with a 2-pole transfer switch, connect the two utility source hot lines to Transfer Switch Terminal Lugs N1 and N2. Connect the standby source hot lines (E1, E2) to Transfer Switch Terminal Lugs E1 and E2. Connect the load lines from Transfer Switch Terminal Lugs T1 and T2 to the electrical load circuit. Connect UTILITY, STANDBY and LOAD neutral lines to the neutral block in the transfer switch.

SYSTEM CONTROL INTERCONNECTIONS

Prepackaged home standby generators are equipped with a terminal board identified with the following terminals: (a) UTILITY 1, (b) UTILITY 2, (c) 23, and (d)

194.Prepackaged load centers house an identically marked terminal board. When these four terminals are properly interconnected, dropout of utility source voltage below a preset value will result in automatic generator startup and transfer of electrical loads to the "Standby" source. On restoration of utility source voltage above a preset value will result in retransfer back to that source and generator shutdown.
