|
|
|
|
## Part I. General
|
|
|
|
### 430.1 Scope.
|
|
|
|
This article covers motors,
|

## Part II. Motor Circuit Conductors
|
|
|
|
### 430.21 General.
|
|
|
|
Part II specifies ampacities of conductors
|
|
that are capable of carrying the motor current
|
|
without overheating under the conditions specified.
|
|
|
|
Part II shall not apply to motor circuits rated over 1000 volts, nominal.
|
|
|
|
Informational Note:
|
|
For over 1000 volts, nominal, see Part XI.
|
|
|
|
Articles 250, 300, and 310 shall not apply
|
|
to conductors that form an integral part of equipment,
|
|
such as motors, motor controllers, motor control centers,
|
|
or other factory-assembled control equipment.
|
|
|
|
Informational Note:
|
|
See 110.14(C) and 430.9(B) for equipment device terminal requirements.
|
|
|
|
### 430.22 Single Motor.
|
|
|
|
Conductors that supply a single motor
|
|
used in a continuous duty application
|
|
shall have an ampacity of not less than 125 percent
|
|
of the motor full-load current rating,
|
|
as determined by 430.6(A)(1),
|
|
or not less than specified in 430.22(A) through (G).
