type of cable permitted in a conduit

My client's electric service is 300' form the base to the house. they ant a 120V20 amp wiring run from house to base. Can a 120V 20 amp line be run in the same conduit that is bringing the 400 amp entre calbe to the house?

No. The service conductors cannot share a conduit with any other circuit. Reference NEC 230.7.

Where is the service disconnect located?

Yea as long is this is a feeder after the main 400 amp there is no code to prohibit the 20 amp circuit. it is just like any other conduit sharing circuits.

Wouldn't it be easier to put a small panel at the meter base to provide this 20A circuit instead of running a 300' long circuit all the way back to the meter? If they truely have a 15A or 20A load, you're going to need a large wire or will need to use a small transformer at each end.

Seems to me the least expensive install would be Service conductors (3 wires) in a 300' run to house and a tap off of those to a small SUSE panel near the meter.
