Eaton 93PM Sidecar Integrated Accessory Cabinet-Bypass (150 kW and 200 kW SIAC-B) Installation and Operation Manual P-164000387—Rev 08 27For four-wire SIAC-B external power wiring recommendations, including the minimum AWG size of externalwiring, see Table 4 or Table 5. Wire sizes listed are for copper wiring only.NOTE The UL 924 Emergency Lighting UPS utilizes the SIAC-B for maintenance purposes only.The SIAC-B is not used for protection of conductors and is utilized as a switchingcomponent only. Use the tables provided in the applicable Eaton 93PM UPS Installationand Operation manual, listed in paragraph 1.7 For More Information, for the appropriateconductor and upstream breaker size.Table 4.
