Contact Centralia City Light or call 360-330-7512 and request that someone be scheduled to come to your house to disconnect the power. A City Light representative will disconnect the power to your electrical meter base.
Please note that any internal electrical work requiring this kind of disconnection will also require a Labor and Industries Permit. Do not disconnect power, remove the meter or meter seal yourself. If this is done by anyone other than a qualified City Light representative, the account owner will be billed for meter tampering. In addition, disconnecting power, removing a meter, and/or tampering with meter seals without proper training and protective equipment is dangerous and violates state law RCW 80.28.240 and CMC 13.04.165.
