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.
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.
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.
18.5kw 400 volt is amp?
I = W/E, 18500/400 = amps
