I hope you guys can solve a mystery I've encountered in renovating my kitchen. There is a double switch with 2 incoming circuits (21A and 23B). Circuit 21A controlled a light over the stove that I no longer need. Circuit 23B controls a ceiling light which I'm keeping. I want to replace the double switch with a single one that controls the ceiling light on circuit 23B and use 21A to power a new range hood that does not need a wall switch because it has its own. When I opened the box I expected to find 4 cables, 2 incoming and 2 outgoing. But there are only three: 1. Incoming cable 23B 2. Incoming cable 21A 3. Unidentified cable which I assume is outgoing I don't understand how there can be 2 incoming cables and only 1 outgoing. Attached to the double switch are: -- The black wires from all 3 cables -- The white from 23B The whites from 21A and the third cable are attached separately. My questions: 1. I now need only one switch on circuit 23B. What kind of switch should I get -- single pole? 2. How would I wire the new 23B switch? 3. I need 21A to power the new range hood that has its own switches. I've already run new cable from the box to the location of the new hood. I assume I'd simply connect the 21A cable to the new one, black to black and white to white. Right? Thanks

I thought guys might appreciate a picture of what can happen when you have a lazy outlet that does not hold a plug well. Thing is on this one it did not blow the breaker....it just kept arcing/burning until the plug lost complete contact. Of course lucky no fire occurred.[ATTACH]53659[/ATTACH]
