comment Can two 30 ampere circuits be combined in an outlet?
@PhilipNgai If an appliance requires a neutral, then it probably uses the neutral for 120v components on the appliance (fans, lights, etc.) Normally they probably will not draw enough current to overheat anything. However, the point is that there is enough supply current available in this scenario to overheat the neutral (likely in some kind of a fault-type condition) and cause a fire rather than pop the breaker.

@Ecnerwal Good point. But still easy for a someone to do a little work in the panel and inadvertently cause a 240v short in the circuit pair by reversing one of the two circuits. Editing my post now.

Do you have room to fur out the wall a couple of inches?

@DaveTweed I would say if the tiles are not plumb, then it's best (visually) to match the tile unless you've got a door jamb or something else plumb very near this finished corner.

what are we looking at on the right half of the picture? an unfinished wall surface? or are we looking at the end of a partition wall and an opening?

comment Custom lighting switches
I don't see any 3-way switches with locator lights. Probably because not all wiring configurations guarantee a neutral will be available in the box. Would you consider glow-in-the-dark switches or an always-on nightlight nearby?

comment Can I accelerate caulk drying by using a fan or heater on it?
if it is a silicone caulk, which is what would be recommended in a kitchen, then increasing the humidity will speed the cure. I will often lightly spray some water mist on the bead to help it cure. Latex-based caulk will cure faster with heat.

comment Are sheet metal screws required for connecting round duct branches?
@Tester101 Basically, I am curious if in most areas of the US, a building inspector would give ductwork a pass in a residential home without screws.
