The so-called SIL (surge impedance loading) of a transmission line is given by P = U2 : Z, where P is the power tansmitted, in MW, U is the line voltage in kV, and and Z is the surge impedance of the line, in ohm. For a 132 kV overhead transmission line, it is typically 400 ohm. The SIL is the power trasnmitted that causes the minimum of losses, that is, it is the most economical condition to operate the line. For example. P = 1322 / 400 = 43.56 MW =43,560 kW The current per phase is I = P / 1.732 U = 43,560 / (1.732 x 132) = 190.5 A If the cable is ACSR (aluminum cable, steel reinforced), it can carry about 1 A/mm2 So a conductor of about 200 mm2 cross section would be a good choice. This calculation just gives a rough idea of the size of the conductor, since the best result is given after several other factors are taken into account, e.g., length of the line, cost of energy loss, cost of cable, cost of steel structures, standardized cable sizes available, etc.
For a 132kV line, typically a conductor size of around 150-300 mmΒ² would be used, depending on factors such as the required current-carrying capacity, voltage drop considerations, and local regulations. The choice of conductor size will be based on engineering calculations to ensure that the line can safely and efficiently transmit power over the desired distance.

For 14/2 NM cable, a 14 AWG equipment grounding conductor is used.
When utilizing the volume deduction permitted for fittings, you need to ensure that the conductor size allows for a safe and efficient flow of electricity without exceeding the maximum fill capacity of the conduit. It's recommended to consult with the National Electrical Code or a qualified electrician to determine the appropriate conductor size based on the specific application and code requirements.
For a 100 amp panel, a #4 copper or #2 aluminum conductor would typically be used as a neutral conductor. It's important to consult local electrical codes or a licensed electrician to ensure compliance with regulations and safety standards.
The steel used in the fence is a conductor of electricity.

Your question is rather vague but, for a.c. systems, a switch must always be placed in the line conductor, neverthe neutral conductor.
The size of a current is determined by the voltage applied, the resistance of the circuit, and Ohm's Law (current = voltage / resistance). The type of conductor material used, the temperature, and the cross-sectional area of the conductor also affect the size of a current.
For 14/2 NM cable, a 14 AWG equipment grounding conductor is used.

This question is gobbledegook and probably intended as harmless nonsense.
The most commonly used conductor of electricity is copper. For larger size service conductors the most commonly used conductor for electricity is aluminum. Aluminum service conductors are used to keep the overall cost of the project lower and are lighter to work with than copper wire.
The equivalent mm2 cross-sectional area of a 5.26 mm2 conductor is a # 10 AWG conductor. A # 10 AWG conductor size is protected by a 30 amp fuse.
Copper is a good conductor and is fairly strong. It generally is not used in power transmission lines due to cost - generally aluminimum is used.
