rewire and new service entrance wire
have a utility pole approximately 25ft from the house, with a utility service meter and electric box below the meter. The service entrance wire is 100amp and enters the house at a connection at the attic floor level and then runs 12ft through the attic and 5ft down the wall to a new 100amp service panel.
I want to replace the service entrance wires that run through the house with copper. What size wire would that be? and does it need to run through conduit?, plastic or metal?
Would the service panel in the house be a secondary panel and therefore not be connected to a grounding bar? There is a grounding wire on the outside of the house (where it enters the house) which is connected to the service entrance ground wire and down to a grounding bar next to the foundation.
