Newbie to this forum here. I have a question that I need to resolve fairly soon. I have 10/3 from a dual pole 30A breaker using one side of the breaker from the main panel that is direct burial wire going to a junction box outside the house. I need to supply a sub panel to a building. Can I use (2) separate 10/2 UFB wires tied into the junction box and share the neutral and ground wires and use both sides of the 30A double pole breaker? I've read that there may be magnetic field concerns on the neutral. The subpanel has only single pole 15 and 20A breakers on it.
If possible it would save me money and time as there is currently a 10/2 UFB supplying the subpanel with a jumper to make it a 120V panel. Please respond asap as I need to make a decision and get materials etc. Thanks!
