I have to relocate a residential underground lateral service to the exterior of the home. In doing so, the service conductors won't be long enough to terminate in new SE Rated ATS on the side of the house. (rural area - meter can is located 250 feet away out on property entry) My plan is to attach a NEMA 3R can to the side of the homes foundation to splice the conductors. In order to keep them accessible, I'm creating an open air bulkhead/vault (area approximately 36" wide x 48" long and 36" deep) with have adequate drainage as not to accumulate water and will have a removable "hatch" covering it to allow access. Anyone see an issue with this?
