GENERAL INFORMATION sEctioN 1.2iNstallatioN BasicspoWer Source and load lineSThe utility power supply lines, the standby (genera-tor) supply lines, and electrical load lines must all beconnected to the proper terminal lugs in the transferswitch. The following rules apply: In 1-phase systemswith a 2-pole transfer switch, connect the two utilitysource hot lines to Transfer Switch Terminal Lugs N1and N2. Connect the standby source hot lines (E1,E2) to Transfer Switch Terminal Lugs E1 and E2.Connect the load lines from Transfer Switch TerminalLugs T1 and T2 to the electrical load circuit. ConnectUTILITY, STANDBY and LOAD neutral lines to theneutral block in the transfer switch.SyStem control interconnectionSHome standby generators are equipped with a termi-nal board identified with the following terminals: (a)UTILITY 1, (b) UTILITY 2, (c) 23, and (d) 15B. Loadcenters house an identically marked terminal board.When these four terminals are properly interconnect-ed, dropout of utility source voltage below a presetvalue will result in automatic generator startup andtransfer of electrical loads to the “Standby” source.On restoration of utility source voltage above a presetvalue will result in retransfer back to that source andgenerator shutdown.Part 1Page 130000001GAS MAIN2-5 PSI5-7” WC REGULATORTO HOUSEHOLDGAS METER CAPABLE+HOUSEHOLD APPLIANCESFUEL FLOW OF:OF PROVIDING NATURAL GASSAFETYSHUT OFFVALVE (BASED ON 1000 BTU/CU FT)BTU/HOUR140,000 (7 kW)156,000 (9 kW)215,000 (12 kW)220,000 (13 kW)261,000 (16 kW)294,000 (18 kW)Figure 2.
