IP Rating for Recessed Shower Lighting
NEC 410.10.D The last sentence states marked for wet locations were subject to shower spray. I believe this is interpreted as any area inside the rim of the shower to be a wet location. I know IP54 = NEMA13 provides protection from water spray. None of the NEMA to IP cross references I have have a 4 for the first digit so I am not sure on IP44.
