200kw gen how much amp take Need to know what the volotage and phase the generator is.
Current is about 18 amps per phase. Allowing for power factor and startup, I'd size the wire for 40 amps per phase, which is #5 wire. This wire has a resistance of 0.39 ohm per 1000 ft, which is 0.39 ohms per 305 meter, or 0.09 ohms per 70 meter. At 40 amps, there is a voltage drop on the wire of 40*.09 or 3.6 volts, less than 1% loss, so that is OK. Use 4 conductor #5 copper wire insulated for 480 volts. <<>> A #12 copper conductor will limit the voltage drop to 3% or less when supplying 13 amps for 230 feet on a 415 volt system.
For 3-core twin and earth cables up to 4 sq mm with reasonable air circulation, allow 8 amps per sq mm for copper and 5 amps per sq mm for aluminium. For permanent installations with high usage per day, use 4 amps per sq mm.
A 16mm² cable can typically carry a current of around 70 to 100 amps, depending on factors such as the installation conditions, ambient temperature, and insulation type. In general, for standard insulated copper cables, a common rule of thumb is to assume about 1 amp per mm² for continuous loads. Always consult local electrical codes and regulations for specific applications.
Cross section area =60x10=600Sqmm For copper we can utilised 2 amps per sqmm hence we can load upto 1200 amps easily.
it depend upon the length but for small length we can say 3 amp . . . . . . . . . . . . . . . <<>> 1 sq mm 3-core cable is rated at a maximum of 10 amps but for extended use of up to 6hr per day small cables should be rated at 4 amp per sq. mm, and for continuous use 2 amps per sq. mm..
The ampacity of an electrical cable depends on several factors, including the cable's cross-sectional area (in mm²), insulation type, installation conditions, and ambient temperature. As a general rule of thumb, copper cables can carry approximately 10 amps per mm² for low-voltage applications. For example, a 1.5 mm² copper cable typically carries around 10-16 amps, while a 2.5 mm² cable can carry approximately 16-25 amps. Always consult local electrical codes and standards for specific applications.

For 148 amps per NEC, you would typically use a 3/0 AWG copper cable for a maximum voltage drop of 3%. This size cable is rated to safely carry 148 amps while meeting the National Electrical Code (NEC) requirements. It's always best to consult the NEC and a qualified electrician to ensure compliance and safety for your specific application.
The weight of 500MCM THHN insulated copper cable is approximately 1.002 pounds per foot.

475 amps, per NEC 310-16. Note that this is a maximum; there are many reasons to derate the current carrying capacity of the wire.
Cross section area =60x10=600Sqmm For copper we can utilised 2 amps per sqmm hence we can load upto 1200 amps easily.
To calculate the mass per meter of a 300 sq mm copper cable, first determine the volume using the cross-sectional area and the density of copper. The density of copper is approximately 8,960 kg/m³. Thus, the mass per meter can be calculated as: Mass per meter = Cross-sectional area (m²) × Density (kg/m³). For a 300 sq mm cable (which is 300 x 10^-6 m²), the mass per meter is approximately 2.688 kg/m.

The resistance of a 1.5 sqmm cable depends on its material (usually copper or aluminum) and its length. For copper, the typical resistance is about 12.1 ohms per kilometer, while for aluminum, it’s around 19.5 ohms per kilometer. To find the resistance per unit length, you would divide these values by 1000 to get ohms per meter. Thus, the resistance of a 1.5 sqmm copper cable is approximately 0.0121 ohms/meter.
Cable for 19 amps continuous should have a cross-section area of 6 mm2.
