![]() Is voltage drop going to be a major issue? Even if I don't run anything that needs 240 volts? The main panel is 240 volts, so even if I had 50% voltage drop, my sub-panel could get 120 volts? Or does it not work that way, and I'd really end up with 2x 60 volts? What wire size and type should I use? I think the primary panel might only have lugs for 3/0 or smaller. ![]() Also all have no permits, so even if I went the permit route for the electric it would have to be a free-standing type panel (meant for an RV hook-up) that I would then have to violate anyway to get over to my house, since they don't let you use a normal house panel when the house itself isn't legal - bastards! As with most everything in my area, the house, septic, well, etc. If I go the $8,000 power company way I have to pull permits and all that junk, otherwise I will not. As far as code, I like to follow it when possible, but safety is #1 for me. I have a tractor, so digging the trench is no problem at all. ![]() I haven't purchased any wire yet, or conduit, so really I'm open to any ideas or thoughts. That is only for the transformer, then I still have the cost of the 2 panels and wiring them either way. Not sure if it is worth spending that $8,000 or not. The power company can install a transformer on the other side of the property for about $8,000, then my 2 panels would only be about 150 feet away from the transformer, if I placed it in the middle of them. It could be a few years before I need the 2nd one, for an additional house, possibly never. Currently, the first sub-panel that is 500 feet away is most important, as I will be building a house there soon. I need 1 or 2 100 amp panels on the other side of the property, the first one is 500 feet from the main panel, and the next one another 300 feet beyond that. It has a newly installed 200 amp electrical service panel on one side of the property that is currently only used for a temporary cabin. I've got several acres of forrest land in the northwest USA. Also, I do have others with much more knowledge helping me on this project, and they won't let me do anything stupid. Sorry, but the govt gets enough of my money directly from my paycheck, sometimes I don't feel like giving them even more, but mostly I don't like dealing with their B.S. In fact, a pro will probably be worried by my lack of knowledge and me stating I don't mind doing things without permits or following code 100%. Only put the new 7.5hp compressor, welders, door openers, 2 post lift, bay lights, etc on the shop meter.I'm looking for general advise at this stage, so you don't need to be a pro to respond. The different rate is one reason i will likely leave the shop office lights and minisplit A/C on the house circuit. Pump house is 130' below and 2000' away from our house, thus has its own meter. Our well pump meter never exceeds the minimum $35 monthly charge. Have not yet decided on underground or overhead.īe aware that rates for outbuilding meters are different than residences. In the future will just need to install meter base and feed from pole. 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. Once i set up the A/C i will install the 200A service. I elected to daisy chain a 60A service from the barn for lights, 110v outlets, 5hp air compressor, plasma cutter, and MIG/TIG welders. Shop was to be hooked up to current transformer. My power company requires 1 outdoor light circuit, 1 indoor light circuit, and 1 indoor outlet in order to energize a meter. Contractors fee was appx $1.88k for wiring, labor, and digging trench. All was included in the contractors quote of $4500. Power company connection was an additional $1k. Most likely current transformer can service both shop and house. ![]() It depends on the site and elevation of shop relative to current pole and local power company requirements. Distance of 100' away from current pole may not require an additional pole. Overhead service saves on conduit and trenching cost. The 400A service for our house required 3 1/2" conduit. In my case 200A service is 2 1/2" sch 40. Power company required the trench to be minimum of 36" below current grade.Ĭonduit size depends on your local utility requirements. Click to expand.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.
