Calculations //
Based On Motor Horse Power HP and Specified Current
Input data: Motor voltage (V L-L), Motor horsepower, Cable Temperature Rating (°C), Ambient Temperature (°C), Cable Length (ft) and Acceptable Voltage Drop (%).
Calculated Values: Operating Current (A), 125% Current per NEC (A), “Zero Length” Cable Size, Acceptable Voltage Drop (V), Actual Voltage Drop (V) and Actual Voltage Drop (%).
Note//
Conductor ampacities are based on NEC 2008, Table 310.16 (Not more than 3 current carrying conductors in racewary).

Hi, could you please send me the Cable Size Calculation Spreadsheet?
How to calculate neutral conductor size of 1000 kva and 2000 kva dry type distribution transformer
How to calculate neutral conductor size of 1000 kva and 2000 kva dry type distribution transformer
dear sir how can we calculate the voltage drop, any formula available for that.
Please give me the formula of cable size calculation
In 3 phase and single phase
Please give me the formula of cable size calculation formula
How we calculate electrical load in amp single phase equipment 10000 Watt, three phase equipment 2000 watt. So total load?
What size cable required
Nice information provided by you.,sir really helpful. Thanks
EASSY WAY TO CALCULATE COPPPER CABLE SIZE AS PER AMPS(MOTOR FULL LOAD)
FOR EX: 10 HP MOTOR
3 PHASE MOTOR CURRENT DRAWS 1.25A/HP
10 HP MOTOR FULL LOAD AMPS (1.4*10)=14A
=14+(1.25*10HP)
= 26A
1SQ MM CABLE TAKING AMPS =6A
=26/6=4.33
10 HP CABLE SIZE = 4 SQ MM
how to calculate cable size for EOT crane’s cable.
i.e. Motor KW:15, duty:S4, 150st/hr, 3 phase, 415V cable length 25 mtr(Festoon-Trailing cable) .
thanking you
Hii Sir ,
I am confused in Three phase wire size calculation please let me know exact formula for three phase wire size calculation with multicore and single core cable.
For example Load Current – 45 A , Voltage drop – 3 %, Cable Lenght -10 Meter,
Please tell me how to calculate 4-Core Copper cable size for that ? Please do needful
Thanks
You should use 25 sq mm copper wire 4 core is enough
hi
lwant aske you about how calculate cable size section if it wase almunium or copper
thank yoy so much
How can I use cable size for 440 kW load? Please suggest Me?
I want to know cable size. I have to install a DG set of 40 KVA capacity and length of cabling about 2000M having one outlet about 4KVA at every 10 M
How can calculations electrical load schedule please send me with examples
Very nice
