I am going to start digging a trench to run underground cable from a service pole breaker box to a well house; the distance is 60 feet. The breaker is a 240 V 2-pole 20-20 which will run to the well house water pump pressure switch. The present UF 2-10 AVG with ground cable runs two inches under the ground in the wrong direction and splices somewhere to a yellow TW-INS 10 three wire where it comes out in the well house. As the cable, disconnected and capped, throws the breaker, this seems why we can't keep the breaker on. At night, the breaker stays on for an hour or two with the ground frozen, and then with midday thaw, I can't keep the breaker on. An electrician came out and did not find a short with a multi-meter, but did not use a megger. Even if it is the control box capacitor or relay, I want to upgrade this old cable situation and have a straight, protected run. Hiring a electrician to come out with a megger will be the cost of the job. How deep should the trench be? 12 inches? What plastic conduit is best? Is gluing enough for the seal? I read that the yellow submersible 600V TW-INS 10 AWG line is good for conduit. I would like to run additional wire for a socket; should that be 12 gauge black and white with ground? Thanks for any advise! The full story is in the well section. I am moving over here for the underground line. Thanks!

I want to know if it worth re-wiring my house wile I have sheet rock down. The house was built in the early 60's. It has circuit breakers and 2 conductor 12 gauge copper wiring with ground, but I have never seen this type of wire. It is labeled "Diamond DTX 12-2-6 Type NM 6oo volt". It is like Romex except it has a cloth like coating instead of PVC.
