Does the Nec allow grounding electrode conductor to be run in conduit that has other conductors in the conduit and what code section?
No, the bare copper grounding conductor can not be in a conduit with other conductors. It can be in conduit by itself to provide mechanical protection for the wire.
How many12 gauge wires can you use in a 1 inch conduit?
The NEC allows 26.
Can you run different phases in the same conduit?
In the US, the National Electrical Code (NEC) will allow you to install single phase and three phase systems in the same conduit.
What is the maximum allowable conductor fill of any trade size conduit used as a raceway?
It depends on the wiring, the current load in the wiring , and the distance. The NEC Code book has the charts for this.And the size of the conduit.
What is the depth requirement for an under ground electrical mains cable?
Metal conduit must be buried to at least 6 inches. Non-Metal conduit must be buried to at least 18 inches. Direct bury wire must be buried to at least 24 inches. This is what the NEC requires but your local codes may be even deeper. Check with your local utility to see what they require.
