Do you have a locator service? We are building a garage and don’t want to disturb any utilities.
To locate underground utilities, call 811.
Can I buy my service wire from PLC?
No. PLC does not sell underground service conductors, wire or meter bases.
If the power lines in my area are being converted from overhead to underground, do I have to convert (underground) my overhead service to my house?
No. However, we are currently offering incentives to encourage our members. We will provide the necessary conduit and wire, and we will waive the trip fees if the service is converted within6 months of our system conversion in your area. Members are responsible for hiring an electrician, providing the trench and arranging any necessary permits and inspections. The Engineering Department can provide trenching specifications, as well as information on state permits and inspection requirements.
Can I have my meter base installed on the back of the house?
No. Please contact the Engineering Department with regard to approved meter base locations.
Can I directly bury my underground conductor?
Yes. However, we recommend all service conductors to be in gray-wall, electrical-approved conduit.
Can I install my own electrical service?
Yes, but all work must be approved by the Washington State Department of Labor and Industries Electrical Division.
Can I put my sewer tight line in the same trench as my service cable?
Yes, but there must be a minimum of 4 feet separation.
Can phone, TV cable, and gas go in the same trench?
Yes, with a minimum of 6 inches of horizontal and vertical separation. Gas lines require a minimum of 12 inches of horizontal separation.
How deep should my service trench be?
Minimum required cover is 24 inches.
