Jth isnt too far off in material costs. 1500-2000 for panels, fittings, meter box, wiring, breakers etc.
Conduit and trench if going underground figure another 600-1k in material. 200amp will be 3" conduit at a minimum.
My $1500 materials was 2 yrs ago and included the in ground pvc conduit, 2 1/2" sch 40 galvanized sweep ells, 40' of galvanized riser and pole conduit, weather head on pole, meter base, and 200A panel set (200A main, and assortment of 15A, 20A, 30A(240v) breakers. Renting a 48" trencher was another $250. Power company required the trench to be minimum of 36" below current grade.
Conduit size depends on your local utility requirements. In my case 200A service is 2 1/2" sch 40. The 400A service for our house required 3 1/2" conduit.
Overhead service saves on conduit and trenching cost. Distance of 100' away from current pole may not require an additional pole. It depends on the site and elevation of shop relative to current pole and local power company requirements. Most likely current transformer can service both shop and house.
Power company connection was an additional $1k. All was included in the contractors quote of $4500. Contractors fee was appx $1.88k for wiring, labor, and digging trench .
My power company requires 1 outdoor light circuit, 1 indoor light circuit, and 1 indoor outlet in order to energize a meter. Shop was to be hooked up to current transformer. I elected to daisy chain a 60A service from the barn for lights, 110v outlets , 5hp air compressor, plasma cutter, and MIG/TIG welders. Once i set up the A/C i will install the 200A service. Currently have a jumper from a 100A service box (supplied via a 60A breaker in barn) to the 200A service panel on wall of shop where meter base will go. In the future will just need to install meter base and feed from pole. Have not yet decided on underground or overhead.
Be aware that rates for outbuilding meters are different than residences. Our well pump meter never exceeds the minimum $35 monthly charge. Pump house is 130' below and 2000' away from our house, thus has its own meter. The different rate is one reason i will likely leave the shop office lights and minisplit A/C on the house circuit. Only put the new 7.5hp compressor, welders, door openers, 2 post lift, bay lights, etc on the shop meter.
