Sizing Transformer Protection. — nec 450.3. Section 450.3(b) covers the protection of the transformer windings, not the conductors supplying or leaving the transformer. Ideally, no engineering effort is required, and it’s very inexpensive. To protect the windings of a transformer against overcurrent, use the percentages listed in table 450.3(b) and its applicable notes. — overcurrent protection. transformers are protected primarily against faults and overloads. The overcurrent protection required for transformers is consider for protection of transformer only. The type of protection used should minimize the time of. — the protection for transformer banks where the secondaries are connected together by a bus tie breaker is. Such overcurrent protection will not necessarily protect the primary or secondary conductors or equipment connected on the secondary side of the transformer. For currents of 9a or more, sec. for more specific sizing recommendations, refer to tables 4 and 5 for class j fuse protection and tables 6 and 7 for class cc fuse protection.
