Here is the situation, Residential customer wants to locate his meter socket 50ft from his new house and run the service conductors(4/0 3cond URD) 18in under grade in conduit(for the 50ft) through the foundation wall into a 4ft high crawl space and then another 8ft to the floor of the utility room and then up to the disco/load center combo.I believe the code says that the inside disco shall be located nearest the point of entrance of the service conductors.Is 8ft close enough? Chris
Good suggestions guys!The customer doesn't want any "electrical clutter"on the side of the new house.I think I will have the AHJ come out and take a look see,before I run any service.All the other rough in is complete. I thought that I had this all agreed to before I started this rough in but the customer changed his mind however he is willing to pay the extra.OK with me! Chris

Remember to establish a ground electrode system at the house, even if you set electrodes at the pedestal. Code requires a electrode system at each structure served. Code wise, I don't think that a ground electrode system is required at the pedestal, as the pedestal would not be considered a structure. If it were my job, I would set an electrode at the pedestal in addition to the required electrode system at the house. Rick

The service disconnecting means shall be installed at a readily accessible location either outside of a building or structure or inside nearest the point of entrance of the service conductors.
So it seems outside could be any readily accessible location.
But 225.32 says
The disconnecting means shall be installed either inside or outside of the building or structure served or where the conductors pass through the building or structure. The disconnecting means shall be at a readily accessible location nearest the point of entrance of the conductors.
So for 225.32 even an outside disconnect has to be nearest the point of entrance.

Based on the code info presented I am ready to put the meter socket and the disco within 5 feet of the outside the house on a pedestal with the double set of electrodes(one for the pedestal and one for the inside panel).Thank you for your help. Chris
