NEC 410.116(B) requires that all recessed fixtures in direct contact with insulation be IC rated. Ic came to my attention a short time ago that several manufacturers (Lithonia, Progress for example) now make dual rated rough=in kits. They are rated IC/non IC depending on the trim used and the wattage of the lamp installed in the trim.
One location that concerned me was a shower light since the closed (wet location) covers were restricted to a 40 watt lamp.
My question is: am I making a big deal about nothing and if you have run up against this in your jurisdiction, how did/are you handling it?

I do not think that you are making a big deal about nothing. The concern, in my opinion, is valid. The only suggestion that I can make is to note the rough-in inspection (make a note in the computer) "dual-rated cans, check shower trim on final" or something to that effect.

I do & would suggest exactly what Nick has described. I make as many notes as necessary on rough inspections that require special consideration at final. I also advise the permit holder / contractor of the issue and that I will be paying special attention to the matter at final.

Example:

"Recessed luminaires over shower in master bathroom requires specific trim & lamp ratings to maintain IC ratings. Will check at FINAL. Advisory Only."

Using incandescent 40 w. lamps is a waste. You have to cup your hand around the fixture to see if it is on! Good news: a 26 watt CFL will ± 100 watt light output AND still be below the listing.

We always pass fixtures rated for "Two 60 watt lamps" in bedrooms. Why not the shower trim?

We are "INSPECTORS" not "EXPECTATORS" or "SUSPECTATORS"

there are lots of opportunities for over-lamping. For years I made a living setting J-Boxes in the attic and cutting the burned wire back where they had put two 100 watt lamps in an enclosed kitchen drum fixture (or similar). The 40 watt shower tirm is an example. GOOD NEWS: the fixture has a hightemperature cut-off that will blink the light off and not continue to overheat. if it works.

So what is your point? That a 40W bulb will not be sufficient? Agree, but I didn't design the place, I just inspect it. The original poster had a valid point, and maybe red-tagging a final or two for this issue, it might make the builder reconsider using the inferior can with the 40W A-bulb as part of the design. Then again, maybe not.

As far as the thermal cutout, I believe we all know about it. But if the electrical inspector suspects over-wattage bulbs, he should check. The fact that a thermal cutout exists doesn't allow the electrical inspector to skate on by...but this is just my opinion. Seems logical to remove a panel cover on a final as well -- or would that make one an "Electrical Suspector?" While we're at it, I also remove a faceplate here and there. You would be surprised how many ungrounded switches I catch, along with 314.20 violations -- especially on a microwave receptacle or any outlet box installed where there is wainscoting or some other type of cabinetry or wood. I guess you can count me in. I'm definitely an Electrical Suspector.
