Standing inspection with fire Marshal. Pressurized line from propane tank to generator. 15lbs for 15 mins. Line held fine. Lost no pressure. (Line actually was charged for over an hour with no movement on gauge.) Fire Marshal came out and signed off on inspection. Backfilled trench and hooked up gas line to generator. The county of placer also showed up and signed off on job as well. While county inspector was on the job, the inspector stated that he was going to sign off on the yard gas but to get a complete sign off on the job the contractor for the electricians needs to call back the fire inspector and the county for complete sign off. Plumbing contractor part of job is signed off and we are good to go.
