I have been attending classes, seminars, and various other educational trade shows since the early 1980’s and just wanted to share with you how much I enjoyed the JCR Production 2014 Code Reviews in Asheville.

Not only did Jeff educate us on the recent changes in the 2014 NEC, but he also shared with us some of his valuable experiences from his time in the industry. His use of analogies and short stories reinforced the points, and made learning from him an enjoyable experience. I especially liked his example of electrical conductors “dressing up” in the appropriate insulation for the job.

I look forward to signing up with JCR for more continuing education in the future!

This Class Covers:

CODE ORGANIZATION / ARRANGEMENT 

A complete review of the organizational flow of the NEC. Beginning with 90.3 Code Arrangement, and breaking down the four affiliations within the structure of the NEC such as; General, Special, Communications, and Chapter 9. We cover the possible modifications that may occur between the General and Special Chapters using several examples, and we continue to identify many common and affiliated groups of articles which work together in common themes (IE; paralleled numbering system). The intent of this review is to show the overall ease of use of the document by showing its uniformity and obvious flow of affiliations. Also included is an organizational coverage of the “Parts” of the Table of Contents to assist in researching information.

CONDUCTOR SIZING & GENERAL WIRING 

All of Chapter Three is covered for General Wiring requirements with a special focus on proper conductor selections based on ampacities and conditions of use. All conductor voltages (0 to 35,000 V) are addressed for proper table usage and selections. All deration requirements and procedures are reviewed and worked through various examples of single and double deration conditions. Neutral identifications and requirements and sizing are strongly discussed in this subject with a warning for identifying and dealing with harmonically loaded neutrals in wye systems.

RACEWAY APPLICATIONS 

Articles 342 through 392 are covered for all raceway types and allowed usages and requirements. Chapter 9, tables 1, 4, & 5 are covered for all raceway fill requirements including the special notes for specific conduit and tubing installations. Raceway fill exercises are completed in class for conduit & tubing, wireways, and cable trays.

OVERCURRENT PROTECTION 

(0-600 volts & over 600 volts) Conductor protection requirements of 240.4 and the modifications in (A through G) are discussed to properly protect conductors of any size and load condition from 0 to 600 volts. Medium voltage (over 600 volt) requirements are also discussed and worked through examples in class. GFPE, GFCI, and AFCI protection requirements are included in this subject. Additional topics are, tap rules, AIC/RMS ratings and requirements, overcurrent types, usages, and ratings, etc. as time permits.

MOTORS AND MOTOR CIRCUITS 

This subject focuses on the proper sizing and/or rating of motor circuit components such as conductors, protection devices such as overload and overcurrent devices under many conditions of use, controllers, and means of disconnecting motors. Multiple motor types (including hermetically sealed motor compressors) are covered in this discussion. This topic covers Duty Cycles, motor starting issues, correct ampacitiy selections, and motor component location possibilities as in disconnects and controllers.

GENERAL EQUIPMENT

(transformers, lighting, and utilization equipment) The scope of this subject is to review many of the “normal” installation requirements for other Chapter 4 equipment. It includes, but is not limited to, appliances, space heating, luminaires, transformer overcurrent sizing, receptacles, switches, switchboards and panelboards, generators, and other items as permitted or requested in class.

GENERAL BONDING & GROUNDING 

This subject is a strong discussion of the bonding and grounding concept, and the specific requirements for the “line side” and “load side” component selections. Sizing and connecting/bonding conductors and jumpers for services or systems, equipment, enclosures, and raceways are displayed through multiple examples from electrical systems from 100 to 6000 amperes to cover the complete range for properly sizing anything from a grounding electrode conductor bonded to any grounding electrode, to the conductors and jumpers for handling fault current capacity and the clearing of any fault. The main focus with this subject is to develop the understanding of the concept of bonding and grounding, and to know where to go to accomplish this in the NEC and in field applications.
