Question: 1 / 140

What capacity requirement allows additional feeders or branch circuits for service supply?

1000 amperes at 480 volts

2000 amperes at 600 volts

The correct choice indicates a capacity requirement of 2000 amperes at 600 volts, which allows for the installation of additional feeders or branch circuits for service supply. This requirement is significant in that it represents a high enough amperage and voltage combination that typically necessitates more substantial electrical infrastructure to ensure efficient distribution of power across a facility.

Higher capacity supply options like those at 2000 amperes or greater often enable the design and installation of multiple feeders that help distribute power loads more evenly and safely throughout an electrical system. This is particularly important in larger commercial or industrial settings where the demand for power can escalate quickly.

In contrast, other options present either lower amperages or lower voltages that may not adequately support the same level of distribution infrastructure, resulting in potential inefficiencies or limitations in service supply. Hence, the selection of this option reflects an understanding of larger electrical capacity needs and the logical requirement for additional feeders or circuits to manage that capacity effectively.
