I will be moving my meter base and therefore having to replace the 4' run of conduit from the socket on the outside of the house to the load center in the inside basement. Currently the conduit is 2" steel but I would like to replace it with PVC. The local POCO says it is fine to use Schedule 40, but I am concerned that the electrical inspector will want Schedule 80. Are there any guidelines for when pipe is or isn't subject to damage? (I would try to ask the inspector but they are very hard to get in touch with!) Thanks!
