What am I supposed to do here guys??
▪ Try hard have to make you understand what PEC
is all about and what it is not.
▪ Persuade you to acquire, read and study the PEC
so you’ll be a great EE like your profs and a lot of
IIEE guys here today
▪ Show some PEC provisions that may help you in
your Electrical System Design course
What else??
▪ So you will not be doing any of this anywhere
and anytime
And what are you supposed to do here
you cool EE studs??

▪ Stay inside the room

▪ Listen and don’t sleep
▪ Laugh and smile
▪ Take down notes
So how does PEC looks like today

It will look different for the next couple of months…

as finishing touches on its revision is almost done…

Structure and Organization
of PEC Part 1
Volume 1
There are nine Chapters, each of which is divided
into Articles.
The Articles fall into one of four groupings:
General Requirements (Chapters 1 through 4),
Specific Requirements (Chapters 5 through 7),
Communications Systems (Chapter 8), and
Tables (Chapter 9)
Appendices (A – D)

Volume 2 (Chapter 10).

Volume 1
• Chapter 1 – General
• Chapter 2 - Wiring and Protection (2 defend and Protect)
• Chapter 3 - Wiring Methods and Materials (M&M’s)
• Chapter 4 - Equipment for General Use
• Chapter 5 - Special Occupancies
• Chapter 6 - Special Equipment
• Chapter 7 - Special Conditions
• Chapter 8 - Communications Systems (Telephone,Data,
Satellite, and Cable TV)
• Chapter 9 Tables - Conductor and Raceway Specifications
• Appendix A - Electrical Symbols
• Appendix B – Formulation & Other Information
• Appendix C – Conduit and Tubing Fill Table
• Appendix D – Wiring Design Examples

Volume 2
• Chapter 10 Watercraft
 Articles
The PEC1 Vol.1 contains more than hundred Articles,
each of which covers a specific subject.
For example:
• Article 1.10 Requirements for Electrical Installations
• Article 2.50 Grounding and Bonding
• Article 3.0 Wiring Methods
• Article 4.30 Motors. Motor Circuits and Controllers
• Article 5.50 Mobile Homes, Manufactured Homes, and Mobile
Home Parks.
• Article 6.80 Swimming Pools, Spas, Hot Tubs,and Fountains
• Article 725 Class 1, 2 and 3 Remote-Control, Signaling, and
Power-Limited Circuits
• Article 8.0 Communications Circuits
 Parts

Larger Articles are subdivided into Parts.

For example, Article 1.10 has been divided
into multiple parts, some of which are:
 Part 1.10.1 General (Sections 1.10.1.1 - 1.10.1.23)
 Part 1.10.2 600 Volts, Nominal, or Less (1.10.2.1 - 1.10.2.2)
 Part 1.10.3 Over 600 Volts, Nominal (1.10.3.1 -1.10.3.11)
• Chapter 1 – General
• Chapter 2 – Safety Rules for Installation and
Maintenance of Electric Supply Stations and
Equipment
Chapter 3 - Safety Rules for the Installation and
Maintenance of Overhead Electric Supply and
Communication Lines
Chapter 4 - Safety Rules for the Installation and
Maintenance of Underground Electric Supply and
Communication Lines•
Chapter 5 – Work Rules for the Operation of Electric
Supply and Communication Lines and Equipment•
 Sections

 Each PEC rule is called a Code Section.

 A Code Section may be broken down into subsections by letters in

parentheses (a), (b), etc.

 Numbers in parentheses (1),(2), etc., may further break down a

subsection

 Lower case letters with dot, example “a.”, “b.”, further breaks the
rule down to the third level.
