Unbox Transformer

Different Transformer Varieties
This transformer comes with three different sizes of knockouts on the bottom – 0.5 inch, 0.75 inch and 1.5 inch. Remove one of the 0.5-inch knockouts so that you can place the wire up inside the transformer. To do this, place the edge of a screwdriver on the outer edge of the 0.5-inch ring and give it a good solid blow. Repeat this step until the plug is removed.
