Neutral

The grounded conductor.

 

Nominal Voltage

The normal or designed voltage level.

 

Non-Inductive Load

A non-inductive load is a load in which the current is in phase with the voltage across the load. (See Inductive Load)

 

Nonautomatic

Action requiring personal intervention for its control. As applied to an electric controller, nonautomatic control does not necessarily imply a manual controller, but only that personal intervention is necessary.

 

Nonincendive Circuit

A circuit, other than field wiring, in which any arc or thermal effect produced under intended operating conditions of the equipment is not capable, under specified test conditions, of igniting the flammable gas–air, vapor–air, or dust–air mixture.

 

Nonincendive Field Wiring

Wiring that enters or leaves an equipment enclosure and, under normal operating conditions of the equipment, is not capable, due to arcing or thermal effects, of igniting the flammable gas–air, vapor–air, or dust–air mixture. Normal operation includes opening, shorting, or grounding the field wiring.

 

Noninductive Circuit

A circuit in which the magnetic effect of the current flowing has been reduced by one several methods to a minimum or to zero.

 

Nonlinear Load

A load where the wave shape of the steady-state current does not follow the wave shape of the applied voltage.
