What size conduit for four 4 cables?
Conduit sizing is based on the number of conductors that are drawn into it. Without the number of 1000 MCM conductors, an answer an not be given.
What size aluminum wire for a 220v 200a service in conduit undrreground at 180 ft?
250 MCM aluminum minimum
What size of copper do you need for a 1250 amps rating?
There are different combination to obtain a current capacity of 1250 amps. A parallel run of #1250 MCM wires. A triple run of #600 MCM wire. The most flexible run would be with a quad run of #350 MCM wire.
What size wire is needed for 1200 amp service?
This size service can be wired in a few combinations. Two parallel runs of 1250 MCM, three parallel runs of 600 MCM, four parallel runs of 350 MCM. Of the three choices the four runs of 350 MCM wires would be the easiest to handle if there are any bends in the service entrance conduit.
Convert 262 mcm to AWG?
Using the AWG for wire sizes only goes up to 4/0. After that the increases use MCM to size the wire. So your 262 MCM wire size will be same in AWG. There is no 262 MCM in the North American market place. It goes in 50 MCM increments starting at 250 MCM , 300 MCM, 350 MCM, 400 MCM right up to 2000 MCM cable.
What size conduit for 400amps?
The sizing of conduit systems that wire has to be pulled into is dependant on the physical size of the conductor being drawn into the conduit. The second governing factor is the conductor count of the specific conductor that is needed. A 500 MCM copper conductor with an insulation factor of 90 degrees C is rated at 430 amps. This is where the conductor count is need by the service, as to whether the service is single or three phase. In this specific case, the electrical code will allow both single and three phase installations to use the same size conduit. A maximum total of four 500 MCM conductors can be drawn into a 78 mm diameter conduit.

What size ground do you need for 4000 amp service?
500 mcm
What size wire is needed for 600 amp three phase load for underground?
A 1250 MCM copper conductor with an insulation factor of 90 degrees C is rated at 645 amps. If you have ever worked with these sized conductors you would know that it is nearly impossible to bend, let alone pull it into a conduit. Seeing how the conductor size is over 1/0, it can be paralleled up to smaller size conductors to meet the ampacity requirement. The options are, parallel 350 MCM, triple parallel #2/0 or quad parallel using #1/0 size wire. These wires are terminated in double, triple and four barrel lugs respectively. It has to be kept in mind that as the amount of wires increase, so does the conduit diameter size, to accommodate the conduit fill code rule.
What size conduit for 400 amps?
Answer for USA, Canada and countries running a 60 Hertz supply serviceIf you use 500 MCM wire rated at 90 degrees C which is rated at 515 amps and allow for 80% ampacity of the wire which equals 412 amps, the conduit size will be three inches. If you use 700 MCM wire rated at 60 degrees C which is rated at 500 amps and allow for 80% ampacity of the wire which equals 400 amps, the conduit size will be three and one half inches.Before you do any work yourself,on electrical circuits, equipment or appliances,always use a test meter to ensure the circuit is, in fact, de-energizedIF YOU ARE NOT REALLY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.

How can we calculate cable size for 800A breaker?
Wire sizing is based on the load that the conductors carry. The breaker is then sized to protect the wire. To get to an amperage the wires are going to have to be paralleled. The calculations are already sized in the electrical code books, CEC and NEC. These are code books used by North America electricians. A 500 MCM conductor with an insulation factor of 90 degrees C is rated at 430 amps. Four 500 MCM conductors paralleled will give you an ampacity of 1720 amps. The breaker will need to have a 500 MCM 4 barrel lug to receive the conductors. The same thing with the load end, it will also need a four barrel 500 MCM lug.
