We have a NEMA4 junction box in a Class I, Div 2 area. The equipment inside is rated for Class I, Div 2. The wires coming in are connected via wirenuts.
Are wirenuts acceptable in Class I, Div 2 areas??? I'd rather see a terminal block. I can find terminals rated for Ex locations (Cenelec - maybe ATEX now?). Does the terminal block have to be rated for Class I, Div 2 in a NEMA4 j-box?
