If you know the size of the load to be served, multiply it by 125% ( times 1.25) and choose a conductor that is rated for that ampacity or higher.
To calculate the cable size for a 100 kW load, you would need to consider factors such as the voltage of the system, the type of cable insulation, the ambient temperature, and the installation method. The cable size is typically determined by the maximum current the cable will carry without overheating. Using the formula: Cable size (mm²) = (2 x L x I x R) / (√3 x V x cosΦ), where L is the cable length, I is the load current, R is the resistance of the cable, V is the voltage, and cosΦ is the power factor, you can calculate the appropriate cable size for the 100 kW load.
To answer this question the size of the cable or the amperage of the load is needed to calculate the correct wire size and connectors to fit the cable.
The length of the cable is determined by the distance from the center of the distribution panel to the center of the load.
Load cable generally means the final cable before the actual load. So on a clothes dryer the "Load Cable" would be the cable running from the outlet to the actual clothes dryer.

To calculate the load on a 2.5 square mm cable, you can use the formula: Load (in watts) = Current (in amps) × Voltage (in volts). The maximum current that a 2.5 mm² cable can safely carry depends on factors such as insulation type and installation conditions, typically around 20-25 amps for standard installations. To find the load capacity, multiply the maximum current by the voltage of the circuit. Always consult local electrical codes for specific guidelines and safety standards.
100 kw is the power drawn by the load. to calculate the cable size you need to know the voltage. From that you can calculate the current. this decides the cable size. for example if the voltage is 400Volts then the current flowing in the circuit when the load is 100 KW will be 250 amps. (100,000/400). for 250 amps to flow with out causing excessive heating of the cable the cross sectional area of the copper cable should be 150 sq mm.for a round cross section the diameter will be roughly 15mm.
how can we calculate maximum load used if CMD is given ?
If you multiply kVA by Power Factor (Ranges from zero to one) you get watts which is effective power.
for DC load and if its copper wire the cross section of the conductor wire is generally calculated as 1/4 th of the current rating . Eg for a DC load of 16 amp the copper conductor with 4 mm square is selected.
take the full load current 1.732*415*I*0.85*efficiency=115*1000 => I? Depending on the value of the full load current and designed and ambient temperatures of the selected category of the cables, and voltage drop per unit length, you can determine the cable size
The voltage drop on a 1.5 mm cable run of 1.5 kilometers will depend on factors such as the current flowing through the cable, the material of the cable, and the temperature. Typically, to calculate voltage drop, you can use the formula: Voltage drop = (2 x current x length x resistance) / cross-sectional area.
