What gauge wire for 240 volt at 40 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.
Can you use 12 gauge wire with 600 volt capacity to hook up an 300 amp 220 volt dryer?
I wouldn't, always safer to go heaver gauge. I recommend 8 gauge if you are going to be running any length of wire. Fire is never fun I believe the above answer assumes the question was meant to read, "30 amp 220 volt dryer." 12 gauge wire WILL NOT carry 30 amps safely. You need to run #10 copper minimum. It is never a bad idea to upsize, such as the recommended #8, but it is not necessary if 30 amps is what you need.
Can you use 5 60watt bulbs in a light fixture that is wired with 18 gauge wire?
Two thoughts here, one the fixture should be rated at the maximum wattage allowed for the socket the bulb screws into. A label should state "maximum wattage allowed". To do a calculation Watts = Amps x Volts. Amps = Watts/Volts. 5 x 60 watts = 300 watts. 300/120 = 2.5 amps. The electrical code only rates down to #14 wire which is rated at 15 amps. From here you have to make the decision.
What wire 240 volts 20 amps 300 feet?
# 4 gauge THHN or THHW is rated for 95 amps and would normally be the correct wire size. However, at 300 ft. from the source, you definetely will have a substantial voltage drop. Therefore, you need to up the conductor size to # 3 gauge.
What is amperage limit of 12 AWG stranded copper wire?
A #12 copper wire with an insulation factor of 75 or 90 degrees C is rated at 20 amps.A 12 AWG wire should not be connected to a breaker larger than 20 amps. The wire is capable of carrying that current load without overheating and causing fire.
How much can a zip line hold?
About 300 lbs. Maybe, but it depends on the gauge of the wire and the hold of the anchors and weight of the wire itself... more information would help for a better answer.

How many amps is 250 MCM wire good for?
300 Amps if used for service entrance conductors. Table 310.15

What gauge of wire is needed for a baseboard heater 1000 watt 240 Volt 4.2 Amp?
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.
Could you use a 12gauge wire for a 25 amp breaker single pole?
No a #12 wire is only rated for 20 amps. The 40 amp breaker will not protect the #12 wire. A 40 amp breaker should have a #8 wire connected to it which is rated at 45 amps. The only time that a breaker is allowed to be bigger that the wire size rating according to the electrical code is when a motor is connected to the breaker. This is to stop the 300 percent inrush of the motor full load amps from nuisance tripping a smaller sized breaker.
How many amps is a 3 gauge copper wire rated for at 115 volts?
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.
What speaker wire for 300 watt amp?
There is no such thing as a watt amp. To determine wire size you need to know the current. Watts = Current x Voltage, so if you know the applied voltage to the load that consumes 300 watts you can get the answer. If we assume 120 volts as standard home voltage then current is 25 amps. If you had 240 volts it would be 12.5 amps. In general 14 AWG is 15 Amps 12 AWG is 20 Amps 10 AWG is 30 Amps
