Oh, dude, you're hitting me with the technical stuff! So, a 12 gauge copper wire is typically rated for around 20 amps in most electrical systems. At 240 volts, that wire can handle a decent amount of power without getting all hot and bothered. Just make sure you're not trying to power a whole circus with it, you know?
A 750 MCM copper conductor with an insulation factor of 90 degrees C is rated at 500 amps.
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.
Yes, # 4 AWG copper and 100 amps is the max.
ref: http://www.okonite.com/engineering/nec-ampacity-tables.html generally see the latest NEC (National Electrical Code) standard but from the tables with assumed temperatures, the rating for 14ga copper is 15 amps (120V).
At the service entrance you will need AWG 1/0 gauge.
A #3 copper wire with an insulation factor 90 degree C is rated at 105 amps.
10 gauge
A # 14 copper conductor will be fine to carry 8 amps at 120 volts. This size conductor is rated at 15 amps.
You would need to use a #12 copper conductor to continuously draw 14 amps at 120 volts.
10 AWG copper.
When you multiply amps x volts the product is watts. Using this formula W = Amps x Volts should give you your answer.
I would use #12. THHN #12 is rated for 30 amps. <<>> The minimum size wire that you can use, to save overhead costs, is #14 wire which is rated at 15 amps. Home wiring cable has a rating of 300 volts. Also the above answer is wrong, #12 is only rated at 20 amps. If you have doubts about an answer check out the answerer's bio by clicking on their name.
15 amps
The ampacity of a # 10 copper wire with an insulation factor of 90 degrees C is 30 amps. All wire voltage ratings usually drop into two categories 300 volts and 600 volts. Home wiring drops into the 300 volt range and commercial, industrial, drops into the 600 volt range.
A #3 copper wire with an insulation rating of 90 degree C has the capacity to receive 105 amps. This is the most common or standard insulation that most calculations are based on. It is the insulation that governs the rating of the voltage. House wiring cables are insulation rated at 300 volts. Most other wiring insulation is rated at 600 volts. Special wires have a insulation factor of 1000 volts. The higher the insulation temperature factor is the higher the rating of current through the wire becomes. #3 at 60C is 55 amps, at 75C 65 amps, at 90C 105 amps, at 110C 120 amps, at 125C 130 amps, and at 200C 145 amps.
Yes. <<>> A #10 copper conductor with an insulation rating of 90 degrees C is rated at 30 amps. A #14 copper conductor with an insulation rating of 90 degrees C is rated at 15 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.
