It's another first from Carlon® - the first non-metallic junction boxes UL listed with a NEMA 6P rating per section 314.29, exception of the National Electrical Code. Manufactured from PVC or PPO thermoplastic molding compound and featuring foam-in-place gasketed lids attached with stainless steel screws, these rugged enclosures offer all the corrosion resistance and physical properties you need for direct burial applications. Type 6P enclosures are intended for indoor or outdoor use, primarily to provide a degree of protection against contact with enclosed equipment, falling dirt, hose directed water, entry of water during prolonged submersion at a limited depth and external ice formation.
