Specifically, the exis6n; service entrance oil circuit breaker experienced severe damage anc: <br />rendemd it inoperaUve. The elecUical system, in addition to the damaged ci�uit bieaker, includes an a's <br />gap fused disconnect switch on the service entrance which is physically located within the Snohomisli <br />County P.U.D.'s fenced transformer yard. <br />The temporary repair will consist of total replacement of electrical conductors, (2) #350 MCIvI <br />conductors/phase, from the air gap fused disconnect switch to the motor wntrol center buss bars, thus <br />bypassing the damaged oil circuit breaker. Over cuirent protecdon will be provided by the air gap fused <br />disconnect switch. This temporary repair has becn determined to be not acceptable as a permanent <br />repair due to the relative inaccessibility (inside locked and fenced transformer yard) of the functional <br />disconnect acavator. <br />The Alderwood Water District will make final repair of the facility, by making approved improvements <br />ro We electrical service in accordance with Nadonal Electric Codes and as required by the State during <br />the winter cf 1990/1991. The medium voltage (2400 volt) system equipment requires 12-16 weeks <br />manufacturing Gme prior to delivery to the site. The District's water system demands during the <br />summer months will make shutdown and �pairs impossible un61 the fall or early winter of this year. <br />The aztached single line diagram pmsents emergency repairs to be made az this time. <br />If you have any questions, do not hesitate to call me. <br />Vcry Uvly yours, <br />i �� <br />Har F..
