Installing recessed lighting...


I'm trying to install recessed lighting in a room that is pre-wired for ceiling fan/lights. I will be installing a total of (4) four Halo H7RICT cans. These cans are rated for IC contact and I will be using romex 14/2 wire.

I have attic access and have already marked where I will be installing the cans. On my wall I have three switches which are pre-wired; one to control a wall receptacle and the other two (see photo) to control the ceiling box.

My ultimate goal is to be able to have 4 recessed lights w/ a ceiling fan attached. The recessed lights being controlled by the dimmer switch (1) and fan controlled by the on/off switch (2).

Here comes my questions when wiring the recessed lights is it ok to tap into each can and only run one wire to the ceiling box? Black to black, white to white, ground to ground. (see diagram)

Also, when I eventually purchase a ceiling fan to install to the box, would I be using the red + black + ground ?

Thanks in advance.

Yes, if the black in the fan box is from the dimmer. It could be the red.

You will use the wire (red or black) that you didn't use for the lights + white........and of course the ground.







The basic circuitry is:

One wire(say black) supplies power to the fan.

One wire (red) supplies power to the lights.

The power from both comes back on the white.

Remember to have the proper cover on top of the recessed lighting unit to:

1. prevent possible fire starting on the attic insullation which would otherwise come in contact with the unit

2. seal the unit to prevent air leaks which would then cause you to consume more energy to head the home in the winter or cool the home in the summer.

I hope this helps,

Educator, Thanks!

Quick question about referring to the "proper cover" are you referring to making certain the electrical plate that comes with the cans is on properly so no wires are exposed with the insulation ? if so: DONE.

Hi Jaysen,

I found this great Bob Villa video on the net that covers it very nicely.

However, it doesn't cover for some reason the sealing material to prevent unwanted air leakage. We had an energy audit done after the recessed lighting was put in place and the attic had the blown insullation added. The energy audit said that there was treamendous amount of air leakage from our recessed lights, but the contractor said that he did install the air leakage covers.

I found this article which talks about air tight recessed lights but that was new to me.

Lastly, here's another one about air seal ratings with recessed lighting.

I hope that helps!
