Wire is sized by the amperage that it will carry. 5 kW is 5000 watts. The equation to find watts is W = Amps x Volts. The equation to find amps is Amps = Watts/Volts. As you can see a voltage is needed to calculate the amperage. Once the amperage is stated, the wire size can be given for that particular amperage.
The size of the wire is stated by its gauge under American Wire Gauge. Six gauge wire is size 6 AWG.
Wire size is governed by amperage not voltage. Voltage is an insulation factor when talking about wire. Add up the amperage of fixtures you want in the circuit. Once that is found then the size of the wire can be calculated.
Use what is called bell wire or thermostat wire.
The minimum size wire that engineers spec for industrial and commercial installations is #12 and it usually is stranded not solid wire.
As with any electrical installation, the wire size used depends on the expected maximum current the wire will carry. That cannot be determined by voltage alone.
That would depend on the type of motor and the manufacturer.
50 sq.mm of aluminium and 25 to 35 sq.mm of copper
The recommended ground wire size according to the NEC Ground Wire Size Chart is based on the amperage of the circuit.
Wire size is the gauge (thickness of wire) hazard is almost anything not wired correctly.
The recommended wire size for a range installation is typically 8-gauge wire.
The recommended wire size for a 30A circuit is typically 10-gauge wire.
The recommended wire size for a 40A circuit is typically 8-gauge wire.
The recommended wire size for a dryer installation is typically 10-gauge wire.
The recommended wire size for an electric range is typically 8-gauge wire.
The dryer wire size chart provides information on the recommended wire size based on the electrical requirements of the dryer, such as voltage and amperage. This helps in selecting the appropriate wire size for safe and efficient installation of the dryer.
Wire size refers to the physical dimensions of a wire, usually expressed in millimeters or inches. Gauge size, on the other hand, is a measurement of the wire's diameter based on a specific gauge system (such as AWG or SWG). So, while wire size refers to the actual physical dimensions, gauge size is a standardized measurement used for electrical wiring.
The recommended wire size for a 220 volt circuit according to the 220 volt wire size chart is typically 10 gauge wire for a circuit with a maximum of 30 amps.
