PEC CHAPTER 1 GENERAL Flashcards
Purpose of P.E.C. 2009:
- Practical Safeguarding
- Adequacy - This Code contains provisions that are considered minimum requirements necessary for safety. Compliance therewith and proper maintenance will result in an installation that is essentially free from hazard but not necessarily efficient, convenient, or adequate for good service or future expansion.
- Intention - This Code is intended for the exclusive use of licensed electrical practitioners (PEE, REE, and RME). This Code is not intended as a design specification nor an instruction manual for a non-licensed electrical practitioner, unless under the supervision of a licensed electrical practitioner.
- Relation to Other International Standards - The requirements in this Code address the fundamental principles of protection for safety contained in Section 131 of International Electrotechnical Commission Standard 60364-1, Electrical Installations of Buildings
Mandatory Rules, Permissive Rules, & Explanatory Material:
- rules of this Code are those that identify actions that are specifically required or prohibited and are characterized by the use of the terms “shall” or “shall not”.
- Permissive Rules - Permissive rules of this Code are those that identify actions that are allowed but not required, are normally used to describe options or alternative methods, and are characterized by the use of the terms “shall be permitted” or “shall not be required”.
- Explanatory Material - Explanatory material, such as references to other standards, references to related sections of this Code, or information related to a Code rule, is included in this Code in the form of fine print notes (FPN). (FPN) are informational only and are not enforceable as requirements of this Code.
