WebTo properly size a transformer, first the primary voltage must be selected. If the primary voltage is 208V, care must be taken to wire only to the 208V primary tap. If the primary voltage is 240V, care must be taken to wire only to the 240V primary tap. 208V wired to the 240V tap will result in low secondary voltage.
