Existing wiring in attic runs over where the can will go. If the top of the housing contacts this wire, will it damage the wire?
IC fixtures do allow for exactly what the IC stands for, insulation contact, so just make sure you put insulation between the housing and the wire. Newer wires are rated for 90°c which is 194°f, and even the older wires that were rated for 60°c (140°f) shouldn’t be a problem with direct contact as a 75w bulb in that housing won’t be all that hot, yet there is no reason not to prevent the direct contact in the first place.

Hey Pete. In regards to this
"WARNING: Do not insulate all around the fixtures – doing that will trap heat inside and cause problems -"
That is not a problem with IC fixtures, as they are designed for "i"nsulation "c"ontact – AKA – IC Perfectly acceptable to have insulation on and around these fixtures.
Not if the fixture is UL/CSA/CE – insert your country here – listed. In those cases, the exterior of the fixture is required to be below melting temperatures – assuming the correct lamps are used. If you install a 100W incandescent lamp in a fixture rated for 40W, all bets are off.
WARNING: Do not insulate all around the fixtures – doing that will trap heat inside and cause problems – many such fixtures these days have a thermal link to reduce the possibility of fires – trapping heat will cause it to trip – and the fixture to fail.
Look for a white (or black) tube about the thickness and length of a lipstick tube – if so equipped, make sure it is uncovered.
it very well could melt the insulation on the wires,,i would put some insulation between the can and wire and use cfl bulbs
There are different recessed fixtures for different situations, insulation present, not present, etc. Check at your home center.
If installed properly, with the right wattage, you won’t have any problems.
No. Unless you over lamp it and take out the thermal protector.
