Laundry-outlet requirements clarified ( not required in some dwelling units )
Optional calculation method introduced for additional loads in dwellings
Grounding of noncurrent carrying metal parts of refrigerators,freezer, and air conditioners.
Extends recognition of double- insulation as a method to eliminate need for grounding
New simplified wiring table for selection of feeder and branch circuit conductor sizes. Increased number of conductors permitted in outlet and junction boxes now includes grounding conductors. Showcases may be interconnected by cords under certain conditions. Requirements for torque motor for determing ampacities. Recognition of instantaneous circuit breakers on motor circuits. Hundreds of Skillfully planned diagrams, photographs, and tables help you grasp every essential...and make the book a valuable key to the code. It feathers an easy-to-follow numbering system...a handy index that lists code rules applying to all types of wiring and insulation jobs to guarantee that no rule is overlooked...and explanations of the code rules are given with the rules themselves whenever needed.
