Written in accordance with the 2005 National Electrical CodeAr, this new book provides readers with a comprehensive introduction to the essential elements of electrical grounding and bonding. It examines the critical concepts of calculating conductor sizes, reading and interpreting NECAr tables, the use of grounded conductor connections in DC and AC systems, as well as various installations and sizing. Material is reader-friendly and is accompanied by straightforward, easy-to-understand explanations of key concepts that foster understanding. A functional use of color and dynamic illustrations augment the book and further support this thorough student- and professional-level approach to electrical grounding.For 208 Y/ 120- volt transformers, the voltage is 208 volts and for 480Y/277-volt transformers, the voltage is 480 volts. ... 208 Y/ 120- volt, 3-phase, 4-wire 480Y/ 277-volt, 3-phase, 4-wire in which the neutral is used as a circuit conductor.
