Hello, new to the forum and first time poster. I'm looking for answers on C1D1 enclosures/jbox...
My situation: I have a septage receiving building previously classified as class 1 div 2. Recently it went under construction, some new equipment was installed and re-classified as Class 1 Div 1. Some of the old equipment (lighting and heat trace are rated C1D2,) and a Stainless steel Nema 4x junction box are still in the room. The junction box is a pull box with 120v circuit for heat trace and wire nut splice, Nema 4x stainless steel, with (1 ) 1" conduit out of slab with seal off, and (2) 3/4" conduits to devices with seal offs leaving the Jbox . Now since the re-classification do i need to have a junction box rated Nema "7" C1D1? I assume yes, but before I buy such an expensive enclosure, I wanted to check here and see if someone can provide me the correct answer and code ref.
Thank you in advance for any useful information.
