This is seemingly to forestall lineman from an over - trust on colour .
Ground Wire Color
The ground conducting wire in your electrical switch or outlet box is n’t really a part of the electric circuit — but in term of safe , it ’s the most significant one , because it divert anomalous stream to terra firma and prevent fervour and burning .

The NEC forbid using basis conducting wire colouring for other conductor .
Neutral Wire Colors
The Institute of Electrical and Electronics Engineers delimitate the electroneutral conducting wire in a electrical circuit as the one with an adequate potency between itself and all the other conductor .
It ’s unremarkably bond to the type of the index supplying and is more right call the ground director — as oppose to the equipment base conducting wire .
This was a grounded director , or impersonal conducting wire , is small than 4 awg and must be identify by a bloodless or grey natural covering , or one with blank stripe .
