Planning The Placement Of Recessed Lights

hi everyone.



i am installing 4" recessed lighting throughout my main floor.  my house was built in the 40's and the previous owner installed drywall over the existing lath and plaster ceiling.  so I've cut a trench down the center of my room to drill floor joists to run wiring and cut my holes for the new lights.

the lights are fire rated and do not require insulated cans for a traditional installation in a drywall ceiling.



question i have is with the additional 1/2 to 3/4" of lath and plaster above the drywall, should these lights now have insulated cans or should i be fine with the cans I've got?  there is no insulation in ceiling.



any suggested would be appreciated.



thanks

Hey,

I'm located in Ontario/Canada and I'm in the process of installing some recessed lights in my uninsulated basement. I was going through the electrical code and noticed that in an 8in^3 electrical box, it is only permitted to have 2 wires and 2 wire nuts.



I have 3 wire nuts (ground, neutral and hot) and two wires coming into each switch.



It seams odd that the light box would not be sized correctly considering its CSA approved. Have any of you come across a similar problem ?



As a side note, I'm also finding it hard to jam 6-8in of cable and 3 wire nuts in this small box !
      

Thanks in advance for the help! 



I am installing a 72" double sink vanity (that I have not purchased yet) and changing from a single light bar to double lights.  I want to make sure that I center the new lights over each sink.  Is there a known spacing I should place these at so they will line up with a standard double sink 72" vanity top?
      

I have a 2 story house, I just had the drop ceiling in the kitchen removed and it will be raised up 12".

Right above the kitchen is the master bedroom. When the new drywall goes up that space becomes inaccessible.



I assume I cannot install "new construction" type recessed lights in the kitchen?
      

Finishing basement and have a few questions...



1. Have already bought recessed cans. Commercial Electric brand. I have now read a few places that these are junk. Why exactly and should I return them? Need to know know before I paint them black.



2. I plan on installing 12 lights on new 15A circuit using 2 switches one for left side of basement one for right (6 x 6). This is OK yes? Both switches will be in same box. And will be only thing on this new circuit.



3. Assuming I am running hot lead from main panel to switch box...there is no fancy wiring that needs to be done correct? 14/2 black to black, white to white except at switch correct?
      

I am redoing my basement, and i am making the electrical runs for the recessed lights in the ceiling. I am using 14 gauge wire, and i have 16 recessed lights with 65 watt bulbs in them, however they are rated at 75 watts max. assuming someone after us may put in the max bulb, the total watts would be 1200, equaling 10 amps. When all of the new wiring is done, i am going to have an electrician connect the circuits to the circuit breaker (using 15 amp breakers) however since i am not comfortable doing this myself, and i would like to use the lights now, can i connect them to the existing 12 gauge wire (this will not overload the breaker... i already checked what else was plugged in to the electrical outlets).



to recap:

The power draw will only be 10 amps at MAX. capacity

existing wiring is 12 gauge/ 20 amp breaker

electrician WILL connect 14 gauge wire to breaker using 15 amp breaker



*THIS WILL BE TEMPORARY*
      

just wondering if someone can give me a quick answer.  I currently have 7 receptacles and 3 lights on one circuit.  the receptacles are in the living room and the lights are in the basement.  I have just installed 6 recessed lights in the living room. does anyone think that that is too much to add to the circuit.  not much gets plugged in in the living room    T.V.  couple of lamps dvd player, occasional vacuum cleaner.
      

I've installed two dimmer switches in the bar area of my basement. It's the dial type, where you can push the dial in to turn the light on or off, or turn the dial to dim the light. One dimmer operates the recessed lights in the ceiling, and the other dimmer switch works a pendant light that I have over my bar. The dimmer for the recessed lights works totally fine. They turn on, off and dim. The pendant lights, on the other hand, only turn on and off. They for some reason will not dim. I checked the voltage on the pendants to see if maybe it was an issue of the switch being a high voltage dimmer operating low voltage pendants, and the pendants are 120V with 75 max wattage. I'm at a stand still. I have no idea what I'm doing wrong. Do any of you have suggestions? I took a couple pictures, not sure what good they'll do. The best I can do for a camera is my iPhone, so they're not the best quality.








      

Hey all, new to the forum and had a few questions about the electric I plan on installing in my basement I am working on finishing.   Here is what the plans call for...



- Bathroom

  - 2 Lights, one GFCI, vent fan

- Home theater

  - Projector, Sound system, various other electronics

- General Lighting throughout

  - 14 Recessed lights approx 60 watt bulbs

  - 14 outlets

  - Mini bar fridge

I will have to run the line from the garage to the basement and my question is should I go 15 or 20 and will I need more than one line to support this?  Any info or direction you guys can give would be greatly appreciated!!

I want to run a new 12/3 to wire a room added on the back of the house. One circuit will be 6 wall outlets. The other will be a ceiling fan and 4 recessed cans. Can I add 2 outdoor lights-using standard outdoor bulbs-to the same circuit as the ceiling lights? Do I use the wall switch(box properly sized) as the junction for the outlet wiring and feed to wall switch for outdoor lights?
