SIS Switchboard Wire: Specifications, Applications, and Selection Guide
Inside switchboards, switchgear, and Motor Control Centers (MCCs), conductor density is extremely high, terminals generate heat, and heat dissipation is far worse than in open building raceways. In these confined, heat-dense environments, standard building wire often fall short. To meet these harsh conditions, electrical codes and equipment standards require a specifically engineered single conductor—SIS wire. […]
