  • NEC Guidelines for Transformer and Transformer Feeder

    Protection at The Primary Side of The TransformerProtection at The Secondary Side of The TransformerCussion For Section 240.21Transformer primary protection— Overcurrent protective devices (OCPDs) are required as primary protection for transformers when the primary voltage is greater than 1,000V [Tables 450.3(A)] and for transformers with primary voltage of 1,000V or less [Table 450.3(B)], with no Exceptions. However, a fire pump has a special requirement for its transformer primary and secondary protection, which is considered a modification to Art. 450. If a transformer serves a fire pump (Art. 695), its primary OCPD shall be sized per the locked-rotor current of the fire pump, and transformer secondary protection shall not be permitted [695.5(B)]. Transformer primary feeder protection— The NEC does not list any specific Exception for transformer primary feeder protection. An OCPD is required for the transformer primary conductor. The only Exception is found in Sec. 240.4(A). If overload protection of the OCPD would create a power loss hazard, such as fire pump application and some processes at refinery...
