The amps that a four gauge wire will handle will depend with the thickness of the wire. If the wire is thin, the four gauge will handle 95 amps.
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.
You would need to use a #12 copper conductor to continuously draw 14 amps at 120 volts.
5000 watts
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.
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.
No, 14-2 wire is typically rated for 120 volts. For 230 volts, you would need to use a heavier gauge wire such as 10-2 or 12-2 to handle the higher voltage and current. It's important to always use the correct wire size for the voltage and current requirements to ensure safety and proper operation.
6 AWG will handle 50 amps with a voltage drop of about 4 volts. If you go to 4 AWG and limit to 50 amps your voltage drop will be 2.5 volts.
34.539 miliamps is only 0.034539 amps. A 16 gauge wire will handle that.
