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
switching component only. Use the tables provided in the applicable Eaton 93PM
UPS Installation and Operation manual, listed in paragraph 1.7, for the appropriate
conductor and upstream breaker size.

NOTE
The neutral conductor is sized the same as the phase conductor for balanced and resistive loads. Non-linear loads, up to the
maximum of 1.5x the load current, require a larger neutral conductor and should be sized in accordance with NFPA NEC 70 Article
310.15(B)(5).
