Depends upon how many amps you need at the load and whether you're using copper or aluminum or some other material, and how much voltage drop your load can withstand during startup inrush.

What size grounding wire do you use as the 4th wire running in your conduit from your 200 amp meter box to your 200amp service panel this is the ground wire from box to box?
You do not use a ground wire in the connection from the meter base to the distribution panel. A bonding wire may be required if the service is using PVC conduit.
Is it permitted to use flexible conduit over 6 feet in length as a grounding means?
No. The new electrical code change does not allow any flexible conduit to be used as a ground means. It is now required to have a green ground wire pulled into the conduit with the other conductors in the flexible conduit. This grounded bonding conductor is not counted as wire fill when calculating the size of the flexible conduit to use
What size rigid conduit for 400 amp service?
4 inch rigid conduit
Can electrical wiring be on ground in crawlspace?
No, the electrical code requires that any wiring system be attached to an adjacent structure. A specific distance is required between holding points on the conduit or cable depending on the size of the conduit or cable. Home wiring is usually stapled every four feet.
What size conduit do you need to install a 4 wire?
NEC code table C10 has conduit fill charts. google for it. Per the table, 1 1/4" inch conduit can support 7 #4 cables. The 1 inch conduit allegedly can support 4 cables but it will be very tight and I would go for the extra room in a 1.25" conduit.
What size should under ground conduit be from pole to meter base?
For new 200 amp services the conduit size should be 3 inch PVC.

Is it legal to support a conduit from another conduit of the same size?
No, the conduit has to be supported individually from a supportive structure. The spacing of the strapping is related to the size of the conduit.
Is it necessary to ground at all metal junction boxes when using metal conduit or cable?
In a completely metallic conduit system it is not necessary to ground each junction box as long as the metallic system has the grounding capacity rating larger than that of the over current device protecting the circuit. The code book states what size conduits are rated at, for grounding amperages.

What size conduit is needed for wiring in Indian houses?
The size of conduit is based on the size of the wires in it. The size of the wires depends on the load connected in the house. Without these other two values an answer can not be given.
What size conduit for 200 amps?
120mm
What is the hole size required for a 2.5 conduit?
A trade size hole for a 2-1/2" EMT conduit connector, the hole needs to be 2-7/8" in diameter. A 3" rigid conduit can also use this size hole without the lock nuts falling into the hole.
