Master bedroom wiring – know what I need

Replaced the outlet at the foot of Andrew’s bed this morning, and it confirms the wiring layout:

  1. Master bedroom ceiling fixture  
  2. Master bedroom switch box
  3. Andrew’s room, outlet at foot of bed
  4. Master bedroom, outlet behind bed
  5. Back basement, ceiling fixture

This is everything I need to know to come up with a plan to redo the wiring. It will be very similar to what I did in Michael’s room:

  1. Disconnect the old wiring between #1 and #2, and replace with a single run of 14/3 which will function as a switch loop.
  2. Disconnect the old wiring between #3 and #4.
  3. Run a new wire from the ceiling box (#1) to the basement.
  4. Mount a new junction box in the basement and splice the new wire into the existing wire between #4 and #5.

An alternative would be to run the new wire directly from #1 to #5, but #5 already has a lot of wires going into it, and I think mounting a new junction box would keep things neater.

The basic idea is to splice the ceiling fixture to the closest fixture downstream of the switch box with accessible wiring, then back-feed the two outlets immediately downstream of the switch.

Anyways, I now know enough about the circuit layout to put it in the wiki.

Incidentally, the old outlet in Andrew’s room was cracked almost in half.  Check it out:

The outlet was most likely original to the house, and it was plastic, not porcelain.  So apparently they were using plastic outlets back then, but not thermoplastic-coated wire.
