A rather thin copper or aluminum wire.
2 AWG.
At the service entrance you will need AWG 1/0 gauge.
Depends on the amperage of the Jacuzzi and if it is 120 or 240 volts.
AWG # 10.
Yes you can. This is what ACSR over head wiring is. Aluminium Conductor Steel Reinforced.
Copper wire gauge sizes are not equivalent to aluminum wire gauge sizes. The gauge sizes for copper and aluminum wires are different due to their differing electrical conductivity properties. It is not possible to directly convert a copper wire size to an equivalent aluminum wire size.
30 amps.
the gauge of the wire determines how much amperage a wire can carry the insulation determines how much voltage the wire can handle
14 gauge wire is for 15 amp circuits. At 220 volts that would be enough for 2.4 kw.At 120 volts it would need 12 gauge wire which is rated for 20 amps.
10 gauge will suffice.
The weight of aluminum wire per foot depends on its gauge or thickness. On average, a 1000 aluminum wire with a gauge of 10 (0.1019 inches diameter) weighs approximately 0.628 pounds per foot. The weight may vary for different gauges of aluminum wire.
A rather thin copper or aluminum wire.
A 100 gauge piece of aluminum has a thickness of 0.0010 inches. Gauge is a universal system used to measure the thickness of metal and wire.
15 amps
A #14 wire will do the job.
For a 500 watt light at 120 volts, you should use a 14-gauge wire to ensure that it can safely handle the load without overheating or causing a fire hazard. This wire gauge is suitable for a maximum continuous current of 15 amps, which is sufficient for a 500 watt load at 120 volts.
