Load Connections – Generator Set Output
For units equipped with T– frame breaker: Installer shall connect conductors in accordance with separate T-frame breaker terminal instruction provided with unit. All conductors shall be sized based upon the 75° C (167° F) ampacities within Table 310-16 of the National Electrical Code, ANSI/NFPA 70, of no less than 100 percent of the maximum current that the circuit carries during rated conditions. All conductors shall be rated 90° C (194° F) or greater. For units equipped with either R-frame breaker or bus bar (terminal strip) connections: Installer shall use UL Listed terminal connectors and install in accordance with terminal connector manufacturer instructions. Terminal connectors shall be used within UL rating limit and suitable for the application. A field wiring terminal shall be sized for the connection of a conductor having an ampacity based on the 75° C (167° F) column of Table 310-16 of the National Electrical Code, ANSI/NFPA 70, of no less than 100 percent of the maximum current that the circuit carries during rated conditions. All conductors shall be rated 90° C (194° F) or greater.Equipment Ground Connection
Illustration 1 g03368914Unit ground bar shall be connected in accordance with National Electrical Code, ANSI/NFPA 70, Article 250. Installer shall use UL Listed terminal connectors and install in accordance with terminal connector manufacturer instructions. Terminal connectors shall be used within UL rating limit and suitable for the application. A field wiring ground terminal shall be sized for the connection based on the minimum ground conductor size required by UL as shown in the corresponding column of Table 1.Over-current protection devices
For units without installed circuit breaker over-current protection option, installer shall use off package mounted UL Listed circuit breaker within 7.6 m (25 feet) of generator set.
