Putting in some lights in my shop. I want to be able to turn on half of the lights at a time instead of burning all of them if i just need to go in to grab something. So here it is. Do i need to split out of a junction box with the supply wire with two wires goin to each switch or tie all neutrals together and all grounds together and have main wire going to one of the switches then put a jumper to the switch beside it. Basicly two circuits from one. There will only be eight flouresant light so i know there wont be an overload of the 12/2 romex main circuit wire. Thanx for suggestions.
