Electrical Wiring – San Jose – Adding Recessed Lighting
The first article in this series on electrical wiring acts as the table of contents for the series.
Adding recessed lighting is like extending any electrical circuit, with a few caveats that are unique to recessed light fixtures.
Recessed light fixtures have two different and distinct ratings:
- IC – Insulation Contact, which means insulation can come into direct contact with the can housing
- AT – Air Tight, which means the recessed what it says, the can will not leak air from the house into the attic
Why do these matter?
Once upon a time, these fixtures got so hot, they would ignite insulation that touched them.
The IC rated fixtures stay cool so this does not happen.
Would you cut a hole in your ceiling then hang a heat source at it?
Probably not, but that is exactly what a non AT rating fixture is.
A non AT rated fixture creates a chimney effect where the warm air created by the bulb rises into the attic, is then replaced by cooler air from elsewhere in the room, which rises as it is heated, etc, etc.
AT rated fixtures radiate the generated heat back into the room, which is what you want.
