Service mast options
I am currently in the planning stages of a service upgrade and am trying to decide how to handle the service mast. The current setup is overhead service with the meter located on the side of the house, which has a hip roof and 2ft eave. The current mast is 2" galvanized steel and goes up the side of the house, through the soffit and through the roof. I'm going to keep it as overhead service, and the new meter will remain on the same side of the house. I'm thinking about just building the new service right next to the current one with a new meter/main panel (required by the local inspector) and a PVC mast up the side of the house with the weatherhead a few inches below the soffit. I'm planning to put the point of attachment (an eyebolt provided by the poco) into the fascia board directly above the weatherhead after installing some blocking in between those rafter tails. I'll also install the new breaker panel and run all of the service conductors and feeders and install the new gec in advance. This way, I'll have everything built by the the time I need the poco to cut the service, and then I can just splice the old circuits to my new breaker panel, get it inspected, and have the poco reconnect the new service (hopefully within the same day).
Does this sound like a viable plan? Going through the roof isn't necessary to meet the clearances required by the NEC or the poco. I'd also like to avoid any penetrations in the roof if I can (I'll be reroofing soon and would take out the old service mast at that time). I thought about just reusing the old service mast, since it's in decent shape, or putting a new rigid steel mast through the same opening, but I'm concerned that I wouldn't be able to accomplish all of that, in addition to splicing my circuits to the new breaker panel, between the time that I get my power cut in the morning and I get it inspected in the afternoon. I'd like to avoid having to build a temp power pole if possible. Are there any downsides to have a pvc mast set up this way? Thanks for any advice or feedback.
