CHAPTER IV
CABLE SIZING CRITERIA
4.1 Calculation Criteria
! Allowable steady state current carrying capacity.
Current carrying capacity is defined as the amperage a conductor can safely carry
before melting occurs in the conductor and/or the insulation. There are many
factors that will limit the amount of current that can be passed through a wire.
Determining factors include: Conductor Size, The larger the circular mil area, the
greater the current capacity. Insulation, The amount of heat generated should
never exceed the maximum temperature rating of the insulation material. Ambient
(surrounding) temperature, The higher the ambient temperature, the less heat
required to reach the maximum temperature rating of the insulation. Conductor
Number, Heat dissipation is lessened as the number of individually insulated
conductors, bundled together, is increased. Installation Conditions, Restricting the
heat dissipation by installing the conductor in conduit, duct, trays or raceways
lessens the current carrying capacity. This restriction can be alleviated somewhat
by using proper ventilation methods, forced air cooling, etc.
! Allowable voltage drop during steady state and transient (motor starting)

Voltage drop is defined as the amount of voltage losses that occurs through all
part of circuit due to impedance. The longer the cable the voltage drop will
become greater. Therefore the voltage drop aspect is critical to supply the voltage
to the loads.

! Clause 210.19(A)(1)
Branch circuit conductors shall have an ampacity not less than the maximum load
to be served. Where a branch circuit supplies continuous loads or any combination
of continuous and non-continuous loads, the minimum branch circuit conductor
size, before the application of any adjustment or correction factors, shall have an
allowable ampacity not less than the non-continuous load plus 125 percent of the
continuous load
! Clause 215.2(A)(1)

Internship*Report*
2015*
Feeder conductors shall have an ampacity not less than required to supply the load
as computed in parts II, III and IV of article 220. The minimum feeder circuit
conductor size, before the application of any adjustment or correction factors,
shall have an allowable ampacity not less than the non-continuous load plus 125
percent of the continuous load.
! Clause 215.2(B)(1)
The ampacity of feeder conductors shall not be less than the sum of the nameplate
ratings of the transformer supplied when only transformer is supplied.
! Clause 215.2(B)(2)
The ampacity of feeders supplying a combination of transformer and utilization
equipment shall not be less than the sum of the nameplate rating of the
transformer and 125 percent of the designed potential load of the utilization
equipment that will be operated simultaneously
! Clause 430.22(A)
Branch circuit conductor that supply a single motor used in a continuous duty
application shall have ampacity of not less than 125 percent of the motor’s full
load current rating.
! Clause 445.13
The ampacity of the conductors from the generator terminal to the first
distribution device(s) containing over current protection shall not be less than 115
percent of the nameplate current rating of the generator
