The recommended cable size for 210 amps would be at least 2/0 AWG (00 AWG) for optimal performance and safety. Make sure to consult the National Electrical Code (NEC) or a professional electrician to determine the exact cable size needed based on the installation requirements and conditions.
To determine the cable size in mm2 required for 450 amps, you need to consider the current-carrying capacity of the cable. The exact size will depend on the type of cable and the installation conditions. For 450 amps, heavy-duty cables with a size of around 240 mm2 or larger would typically be used to ensure safe and efficient operation.
Wire sizes and ampacity are regulated by code. # 14 wire 15 amps, #12 wire 20 amps, #10 wire 30 amps, #8 wire 40 amps, #6 wire 60 amps. These are the most common, a slight variation in amperage depending on the insulation factor.
Two conductor and three conductor #12 Teck cables are rated at 20 amps. This size is one over from the 15 amp rated wire. This is because on motor loads the conductor size has to be 125% of the motors full load amps. Since all that was stated is 15 amps it is better to err on the larger size wire.
The cable size for 700 amps depends on several factors, including the type of cable (copper or aluminum), the installation method, and the permissible voltage drop. Generally, for copper conductors, a cable size of around 2/0 AWG to 3/0 AWG is commonly used, while for aluminum conductors, sizes may range from 250 kcmil to 300 kcmil. It's essential to consult the National Electrical Code (NEC) or a local electrician for precise requirements based on specific conditions.
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.

A 0.15Cu cable has a rating of 382 amps summer and 476 amps winter. 0.2Cu allows 425/530 amps. That is for outdoor use in overhead lines.
70mm 4core copper cable
A parallel run of 750 MCM AWG conductors will handle 1000 amps. if we want 1000amps to flow, 250sqmm cable is enough.
# 2-awg
It is 350 mcm cable and Table 310-16 1996 NEC gives limiting values of 260 amps at 60 degrees C up to 350 amps for 90 degrees for copper, or 210/280 amps for aluminium.
A #2/0 triplex with an insulation factor of NS75 is rated at 210 amps. A #1/0 triplex with an insulation factor of NS90 is rated at 220 amps.
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.
