Terminal Lug Data for General Duty Safety Switches

The terminal lug data for general-duty safety switches defines conductor capacity and wire size compatibility across ratings from 30 A to 800 A.

Terminal Lug Data for General Duty Safety Switches

The lugs accommodate both copper and aluminum conductors, with conductor counts ranging from one to three per phase. Wire bending space and lug wire range increase with switch amperage, ensuring compliance with NEC Table 312.6 and supporting larger conductor sizes required for higher current applications.

note

30–100 A switches suitable for 60 °C or 75 °C conductors. 200–800 A switches suitable for 75 °C conductors.
