Installation of an Additional Wall Dimmer and New Ceiling Light Fixture

Dear Mr. Electrician: Is it possible to install an additional dimmer next to an existing one and connect a new ceiling light to the new dimmer?
Answer: Yes.  However the methods used to achieve this type of installation will vary according to your building structure and the location of the switches and light fixtures.  Below are photos of a simple dimmer and ceiling light installation in a condominium.

This was the existing dimmer switch for ceiling lights in the adjacent room.

The existing dimmer switch box had the correct wiring (Hot and neutral) in it to facilitate the connection to another light fixture.  A long thin screwdriver was inserted along side of the switch box to feel for any obstacles such as pipes or wood studs.

The existing one gang plastic electrical wall box has been removed and the hole has been made bigger for a new two gang plastic old work electrical box.

The existing black switch leg wire was identified with green electrical tape.  The other black wires get spliced together.

The access hole in the wall and the access hole in the ceiling were made using "The Grabowski Method" (Saw at 45 degree angle) to faciitate the installation of a new wire to feed the new light fixture.  A large hole is needed to fit the angle drill into the wall to drill up into the top support plate.

Holes cut out in the ceiling and wall in order to install the wire
 
This hole was made using "The Grabowski Method" of cutting holes in drywall.  You simply hold your compass saw at a forty five degree angle when cutting to give you a beveled edge.  This makes it much easier to patch the hole using the same piece of cut out drywall and some joint compound.  Lately I have been using my Milwaukee Cordless Multi-Tool to cut such holes.

This hole going up into the ceiling was made with a Milwaukee 0721-20 V28 28-Volt Lithium-Ion 1/2-Inch Cordless Right Angle Drill

This view is the inside of the wall through the hole in the previous photo.
The big hole in the wall was needed to accommodate the big angle drill and a long auger drill bit.

A 4-Inch diameter by 2-1/8-Inch depth octagonal box was used here to give better leverage support as the box was mounted on the side using #10 x 1-1/2" sheet metal screws and one fender washer  where the knock out was.

The fender washer allows for a little adjustment to get the box positioned correctly.  The other screws lock it in place.

Note the copper ground wire attached with a 10/32 screw.

I usually leave extra slack on the wires for chandeliers in case the homeowner decides to lower it or use it on a high ceiling in the future.  Having the deep octagon electrical box in the ceiling lets me tuck some extra chandelier wire slack up there.
White electrical tape was put on the chandelier neutral conductor to make it easily identifiable.  Normally shallow ridges on the one side indicate the neutral.

The wires are tucked up inside of the deep octagon electrical box.  This is another good reason to use a deep box, there's more room for the excess wires.

The two gang plastic old work electrical box is mounted to the wall by tightenting the screw in the upper right corner and the screw in the lower left corner.  The wings will be pulled from behind against the wall and create a tight wedge.  In addition a #8 x 1" sheet metal screw was driven through the box into the adjacent wall stud for additional bracing.

A small piece of wood was screwed in place so that the drywall would have something to attach to.  This piece of drywall was cut out using "The Grabowski Method" where the blade is held at a 45 degree angle.
