What is safe load in watts for 12 gauge copper wire over 50 feet at 120 volts on 20-amp circuit?

The total loaded 20 amp breaker operating on 120 volts will handle 2400 watts before it will trip. This is the maximum and the circuit wiring will probably get warm. De-rate to 80% capacity will bring the wattage down to 2400 x .8 = 1920 watts.

How many volts is 2 gauge 200 amp 3 ohms?
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.
What is the typical number of amps per circuit and what is the typical number of volts that enter your home and what is the typical number of volts for each circuit and what is a gfi?
15 amps per circuit 240 Volts total 120 Volts each circuit GFCI=Ground Fault Circuit Interrupter
What gauge cable to run 240 volts?
The voltage has nothing to do with the gauge of wire needed to supply a given circuit. The size wire is determined by the amperage of the overcurrent protection device (circuit breaker, etc.) being used to supply power to the circuit.
What gauge wire to run 3250 watts 240 volts 60 feet along 40 amp circuit for oven in residence?
There's something wrong here. 3250 watts on 240 volts is only 13.5 amps, not 40. And that would be 12 gauge wire on a 20 amp circuit. But that seems low for an oven. If it truly is a 40 amp appliance then the gauge would be #8 wire. The wiring info that comes with the appliance should tell you everything you need to know.
What gauge wire would you need to carry 100 amps at 12 volts dc?
A #3 copper wire with an insulation factor 90 degree C is rated at 105 amps.
What size copper wire do you need for 240 volts 16 amps at 150ft?
10 gauge
What is the max amp for 100' 14 gauge copper wire?
At 120 volts a 15 amp circuit wired with #14 wire used for a dedicated light circuit do not install any more than 1400 total watts in lighting. If used for an dedicated outlet circuit do not install more than 8 outlets.
What gauge wire is required for 25 amps over 100 ft at 240 volts?
10 AWG copper.
How do you measur ampere?
You use an "amp gauge" to measure amps in an actual circuit. It is hooked in series with the load. It can be placed anywhere in the circuit as long as it is hooked in series. Mathematically, you have to know the resistance, or wattage and voltage of a circuit. Volts=amps*resistance or amps=volts/resistance, or resistance=volts/amps. Ohms law!
What size wire to use for a 800 ft run on 20amp circuit?
To answer this question you have to know the voltage and load type. If this was a 110 Volt lighting application 12-2 should work. If this was a 220 Volt motor load 10-2 might be a better choice. Copper wire 120 volts #6, at 240 volts #8. Aluminium wire 120 volts #4, at 240 volts #6. As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed. Before you do any work yourself,on electrical circuits, equipment or appliances,always use a test meter to ensure the circuit is, in fact, de-energized.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
What gauge wire would you need to handle 14 amps at 120 volts?
You would need to use a #12 copper conductor to continuously draw 14 amps at 120 volts.

What does trouble code p0138 on 2001 dodge 1500 mean?
Downstream O2 sensor circuit volts high.Downstream O2 sensor circuit volts high.
How do you check the volts?
by attatching a voltmeter into the circuit you are trying to measure the volts of.
