Here's another tap selector switch. This is on Tacoma Power's 115 kV Cushman lines which run from it's hydroelectric facilities on Lake Cushman to Tacoma. This tap is for a Peninsula Power & Light substation. Pen Light buys it's power from the Bonneville Power Administration buy receives it over Tacoma Power's lines through a "power wheeling" arrangement, since Tacoma Power is the only one with transmission lines in this area.
