Use the general equation for resistance in parallel:
1/R = 1/R1 + 1/R2
For a distribution panel rated at 400 amps parallel runs of 3/0 conductors will do the job.
You call your local electrician to do any work on the service main. He or she will explain it to you, including the bending radius, fasteners, etc.
It depends on the rated voltage of the transformer winding -are you talking about a 12-V transformer winding or a 400-kV transformer winding? Obviously, there is no one answer to your question!
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.
I = W/E, 18500/400 = amps
400 ohms
25 ohmsAnswerResistance is measured in ohms. Conductance is measured in siemens. Conductance is the reciprocal of resistance. So the ohmic equivalent of 400 siemens is 2.5 milliohms.
The voltage across 600 ohm resistor(i.e. between point 'a' and 'b') will be 30V.
