Simple 8 Gauge Wire Circuit Breaker Solutions - Code exchange precis: new textual content became introduced to make clear whilst the dimensions of an device grounding conductor should be expanded in size. The new text requires a careful read and a piece of deep thought with a purpose to absolutely draw close the impact of the trade. Increasing an ungrounded conductor in length due to situations of use does not always create the want to also increase the device grounding conductor of the circuit. If it has been decided that a 6 awg copper ungrounded circuit conductor is the smallest length cord that may carry a 20 amp load after making use of adjustment factors for excessive ambient temperature, then the 6 awg conductor is now "the minimum size that has sufficient ampacity for the intended installation".

In step with the brand new code language, if the 6 awg conductor is connected to a 20-amp overcurrent device, the minimal required size copper system grounding conductor (12 awg according to desk 250.122) can nonetheless perform to carry 20 amps of ground fault cutting-edge below these instances.
The preceding 2011 code language in 250.122(b) required that any time an ungrounded conductor of a circuit was elevated in size (for any reason); the equipment grounding conductor of the circuit turned into also to be accelerated in length, the identical proportional quantity. This code language became too restrictive and unnecessary.
