I. INTRODUCTION 100. PURPOSE The intent of this handbook is to provide information to customers, electrical contractors, engineers and architects in order that electrical installations may be connected to the Company's system in a safe and uniform manner. This handbook is filed with the Maine Public Utilities Commission (MPUC), and it is in conformance with the MPUC’s Chapter 320, Service Standards for Electric Utilities. 101. CODE REQUIREMENTS The Company, by law (Title 35-A M.R.S.A. Section 2305- A), is required to design, construct, operate and maintain its lines and equipment in conformance with the applicable provisions of the most recent edition of the National Electrical Safety Code (NESC). The customer requirements of this handbook are based upon the applicable provisions of the most recent edition of the National Electrical Code (NEC), as approved by the National Fire Protection Association, and said Code is hereby made a part of this handbook by reference. Any additional requirements are established in the interests of safety and convenience. Municipal and State requirements, insofar as they may conflict with anything contained herein, will take precedence. The local or State electrical inspector is the "authority having jurisdiction" and is, therefore, responsible for interpretation and enforcement of the NEC. In accordance with NEC Section 90.4, the “authority having jurisdiction” may, by special permission (written consent), waive specific requirements in the NEC or permit alternative methods. 1 1

Revisions of this information will be made when necessary, and the Company reserves the right to make such revisions. The Company will endeavor to notify those concerned when such changes are made, but cannot guarantee to give such notice to all persons who may have received this handbook. It is urged that all architects, engineers, contractors, electricians, and others who are interested submit their names and addresses to be included on the mailing list to: Central Maine Power Company Meter Services Department 83 Edison Drive Augusta, ME 04336 E-mail: suzanne.hinkley@cmpco.com 103. COMPLIANCE WITH REQUIREMENTS The customer's installation, before being connected to the lines of the Company, shall be in compliance with the requirements contained in this handbook, the NEC, and any other requirements mandated by State law or local ordinance. 104. SPECIAL CASES Special cases may warrant departure from the requirements in this handbook. Any such departure will not be considered as establishing a precedent, nor be considered as a waiver of the Company's right to enforce any of the requirements contained herein. 105. WRITTEN CONFIRMATION The Company will confirm in writing, upon request, all information given regarding service characteristics, applicable rate, service entrances and meter locations.
