A dry-type transformer diagram shows the electrical grounding and bonding configuration for a 408V primary and 208Y/120V secondary system. The equipment grounding conductor connects to the transformer enclosure. A main bonding jumper links the insulated neutral terminal to the ground bar. Phase conductors A, B, and C feed the transformer windings.
