A #3 copper wire with an insulation factor 90 degree C is rated at 105 amps.
The ampacity of an 8 gauge wire at 240 volts would depend on the specific type of wire and the installation conditions. Generally, an 8 gauge wire can safely carry around 40-50 amps of current. It is important to consult the National Electrical Code (NEC) and local regulations for precise guidance.
For a 5kW heater HVAC system, you would typically need to use 10-gauge wire to handle the current load safely. It's important to always consult the manufacturer's specifications or a licensed electrician to ensure you are using the correct wire gauge for your specific setup.
To convert watts to amps at 120 volts, use the formula: Amps = Watts / Volts. For 1500 watts at 120 volts, the calculation would be: 1500 watts / 120 volts = 12.5 amps.
To calculate the amperage, we can use the formula: Amps = Watts / Volts. In this case, it would be 70 watts / 13.8 volts ≈ 5.07 amps. So, with 70 watts and a voltage of 13.8 volts DC, the amperage would be approximately 5.07 amps.
Ohm's Law states Volts = Amps x Resistance. You would need to apply 600 volts across 3 ohm load to have 200 Amps flow in circuit. Not sure what you are really asking and why you mentioned 2 gauge.
At the service entrance you will need AWG 1/0 gauge.
A #8 wire with an insulation rating of 75 or 90 degrees C is rated at 45 amps.
You would need to use a #12 copper conductor to continuously draw 14 amps at 120 volts.

A # 14 copper conductor will be fine to carry 8 amps at 120 volts. This size conductor is rated at 15 amps.
AWG # 10.
30 amps.
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.
A #14 wire will do the job.
140 AMPS
Depends upon the voltage. The formula for amperage or (wire size) is Watts / Voltage. If the voltage is 220 volts, then the amperage would be over 400 amps. This would require a large wire size to run it. If it were 440 volts, the amperage would be 1/2 or 200 amps. That would require a smaller wire size. As the voltage goes up, the amperage goes down. At a thousand volts, the amperage would only be 90 amps. A wire gauge or size of a #2 would carry 90 amps for small distances.
