What size wire for 400 amp distribution panel?
For a distribution panel rated at 400 amps parallel runs of 3/0 conductors will do the job.
What size wire is needed for 400 amp 480 volt service?
A 500 MCM wire with an insulation factor of 90 degrees C is rated at 430. Most 400 amp services will use parallel wires on each leg to feed the circuit. A 3/0 wire with an insulation factor of 75 and 90 degrees C is rated at 200 and 225 amps respectively. The insulation rating of these conductors will be 600 volts.
What size wire for a 4000 amp service?
Generators are rated in volt-amps (va) and may also have a wattage rating. In most practical applications volt-amps and watts are the same. At 240v single phase, 400 amps is 96000 volt-amps, or 96kva. I would be looking for a 100 kva generator. This is a large generator if you are considering it for your home. In most situations you identify critical circuits and place only these on the generator through a transfer switch. This allows for a much smaller generator.
How many amp do you need to run a house?
Minimal 100. Depends on load draw of home. Can be 200 amps or 400 amps as well.
18.5kw 400 volt is amp?
I = W/E, 18500/400 = amps

What size feeder service cable is required in step up transformer 220 to 380V in 300 amp cirquit breaker?
250 kcmil in copper and 400 kcmil in aluminum. kcmil = 1000 circular mils.

What size wire is needed for a 200 amp residential service panel?
A 350 MCM copper wire with an insulation factor of 90 degrees C is rated at 325 amps. If the question is referring to maintaining a load of 300 amps then you have to up size the wire size because the conductor is only allowed to be loaded to 80%. A 500MCM copper wire with an insulation factor of 90 degrees C is rated at 395 amps x 80% = 316 amps.
How many cca in one amp?
cca is 'cold cranking amps' in other words how many amperes can a given battery supply to crank a cold car engine. A good battery can give 400 amps for cold cranking.
400 volts x 45 amps?
400 Volts X 45 Amps = 18,000 Watts

What is 4000 A?
4000 A is 400 Amps.

What size service conductors do you need for a single phase 600 amp commercial panel?
The size of wire for service entrance conductors for a 400 amp 3 phase service could be 500 MCM copper. This is very large size wire and difficult to bend and shape, to connect to terminals in the main disconnect and distribution panel. This problem is solved by using parallel conductors or on higher ampacities triple conductors. Using parallel conductors the wire size would be three ought (3/0) copper.
How many amps equals 400 watts?
Watts = Amps x Volts x Power Factor. Power Factor = 1 for resistive loads and gets smaller for inductive loads like motors. Assuming home voltage of 120 Volts and a PF = 1 your answer is 400/120 = 3.33 amps.
