Finish TradesCâu 266 / 700
A recessed ceiling light fixture is being covered by attic insulation as part of the finish. To avoid a fire hazard, the fixture must be:
a.Wrapped tightly regardless of its rating
b.Left with insulation piled directly on any fixture
c.Removed entirely
d.Rated IC (insulation contact) if insulation will touch it, or kept clear at the required distance if non-IC
Giải thích
Only IC-rated recessed fixtures may be covered directly by insulation; a non-IC fixture must have insulation held back the required clearance to prevent overheating and fire. Wrapping any fixture, piling insulation on a non-IC can, or removing the fixture are wrong responses.
