I need to move a service pedestal approx. 20 feet. I believe the code states that the service must terminate at the disconnecting means within 3 feet of entering the building, originally the panel main. Can I use a disconnect in the new location, and then feed the panel about 18 feet away? The disconnect would be in the crawlspace. Or do I have to pipe along the outside of the house to within 3 feet of the panel before entering?
