General Requirements in the NEC

Listed Equipment

Other General Requirements

Sections 110.4 through 110.8 address some very general issues that are applied throughout the NEC, such as the voltages that are used, the requirements for voltage ratings of connected equipment, conductor sizes and wiring methods that may be used.

Section 110.5 describes conductors and establishes the assumption in the NEC that conductors will be copper unless specified otherwise. Section 110.6 describes conductor sizes as being specified in American Wire Gauge (AWG) sizes or in circular mils. Section 110.7 requires all wiring to be free of short circuits and ground faults, other than as permitted in the Code.  Section 110.8 says only the wiring methods that are approved and included in the Code are suitable and actually covered by the NEC.
