Earlier there was a thread in landscaping about splicing under ground 10-2 to 12-2 at a hub. The question wasnt recieved well there. I was just wondering how this would normally be done. Say if you wanted lights at your drive entrance and a gate opener or something like that and determined the distance warrented 10 wire. with 12 ga wire going opposit directions down the fence etc. Some one said that you cant splice 12 wire to 10 wire. I would assume you can run 10 ga to an above ground box and run 12 from there. no?
