How do you solve for the size of wire when the given is kva?
The V stands for volts and A is amps. If for example you have a 12kVA device and are running off a voltage of 120 volts then Amps = 12000/120 = 100. You then use the calculated amps in a wire size table to get the correct size.
What size conduit and aluminum wire for a 400 foot run on a 120 240 volt system?
The key parameter in sizing wire is the current requirement. Once you know that you can look up value in a wire gauge table. The length of the run is important for longer runs because of the resistance of the wire itself. Aluminum wire requires a larger diameter than copper for the same current. Once you calculate the wire size you can then size the conduit.
What size underground wire do you need from house to building 120 feet away?
The most significant part of the equation is, what will be the maximum current draw? If it's to be a small current draw, for example 40 Amp service (40 amp breaker), you'll use 8AWG wire that's rated for direct burial. Higher current rating will require larger wire. As always, if you have any questions about the proper wiring or how to connect electrical service, contact a local electrical contractor. Understand that improper wiring can result in fire and/or death.
What wire size needed for a RV 30 amp 120v at 90 feet?
For single phase 30 amps at 120 volts you would need a #8 copper wire with an insulation rating of 90 degrees C.
Is red or white neutral for electrical work?
In residential wiring the white wire is neutral on the 120 volt circuits. On a 3way circuit the red is the traveler and the white is neutral. On a 240 volt 3 wire connection the white & black are hot. On a 240 volt 4 wire connection the black and red are hot and the white is neutral.
What size of current does the 1.5mm wire carry?
A 1.5 mm wire is rated at 13 amps at 120 volts.

What wire size needed for 120 volt 3000 watt load?
AWG # 10 wire on 30 amp circuit.
What size wire do you need for 2HP motor with 120 volts?
12/2 with ground.
120 volts 1 phase 30 amps load what wire size?
10 AWG.
What size wire to carry 8 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.
What is the largest factor of 120?
The largest factor of 120 other than 120 is 60 because 60x2=120 The largest factor of 120 other than 120 is 60 because 60x2=120 The largest factor of 120 other than 120 is 60 because 60x2=120 The largest factor of 120 other than 120 is 60 because 60x2=120
What is the Color of neutral wire in 120 volt circuit?
For wiring in the USA the Neutral conductor is required to be white or gray by the National Electrical Code.
What size wire do you need to go 150 feet using a 20 amp 120 v?
12 AWG.

What heat can a small copper coil produce at 120 volts?
Need to know what the size of the wire is in the coil and the physical diameter of the coil.
What is an electric shared neutral?
An electric shared neutral is the white or negative wire that is shared between two electrical circuits on a basic single phase system. Most electrical devices use 120 volts and require a "hot" wire and a neutral wire to operate. Some larger devices use 240 volts and require two "hot" wires to operate. Two circuit breakers in an electrical panel can share one neutral wire as long as the breakers are not on the same "leg" of power. When looking at an electrical panel there are usually two "legs" of power feeding all the breakers, each leg has 120 Volts to ground, if the "legs" are combined you will have 240 Volts. A neutral wire can be shared by two circuits as long as the breakers are on separate "legs". If someone needed to add two circuits in their home, the could run what is called a 3-wire romex, It has a black wire, a red wire, a white wire and a ground wire. The white wire is the neutral for both the black and red 120 volt circuits, and the breakers for the new circuits would need to be on separate "legs" in the panel.
