408-088 - Transformer Ratings and Wiring Helper Card

Product Dimensions
3-3/8in. x 5-1/4in.
1 oz.


This “Helper Card” was developed as a toolbox reference for electricians working with transformers in the field.

Available singly, as well as in 6-packs, 12-packs, and bulk 50-packs, this electrical toolbox reference will be a valuable tool for those working in the field within petrochemical plants, refineries and within the oil & gas industry.

While originally designed as a supplement to several DAC hands-on training aids relating to transformer theory and wiring, we regularly sell this handy reference directly to working professionals and industrial concerns as a handy reference.

As seen in the above illustrations, the card, on one side, provides tabular data on current ratings for both single and three-phase transformers based on varied kVA assumptions, at different voltages. The second side provides refresher diagrams for Delta-Wye and Delta-Delta, three-phase wiring connections.

This is one in a series of handy industrial maintenance” helper card” reference products offered by DAC.
