<p>Tap covers and projections for an electrical device are provided. The tap projections have bosses or taps raised from a surface of the tap projection and encapsulated with a resin except for an outer surface of the bosses or taps. The tap projections may have a channel or recess between individual bosses or taps to prevent degradation of the insulation between the respective adjacent bosses or taps. When a tap cover is provided, it is pushed on or bolted to the tap projection. The tap cover may be provided for an individual tap or an entire tap projection and may be formed of a resin or an elastomeric material. The tap cover has a first generally planar surface and a second generally annular surface having a circumferentially-extending groove on an inside surface. The circumferentially-extending groove is located slightly beneath the second generally annular surface. The groove of the tap cover is designed to fully engage with a raised lip of a tap projection or individual tap of a transformer. Another embodiment of the tap cover has openings to receive epoxy- headed bolts that are used to connect the tap cover to the tap projection through the tap connectors.</p>
