Non-metallic junction boxes are UL listed with a NEMA 6P rating per section 314.29, exception of the National Electrical Code® and CSA certified per section 12 of the Canadian 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.
