For remote sensor mounting gas detection sensors in Class 1, Div 1 environments. UL/CSA certified junction box with six wiring connections. Compatible with Honeywell XNX universal gas transmitters and 705 HT . 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. Junction boxes in a Class 1 Division 2 area that contain only splices and not equipment can be NEMA 1 or whatever you need for the environment that is in the area. There is no requirement that the wiring in the box be IS or non-incendive type circuits. 120, 480 or even 5kV could be spliced on open terminals in a Div 2 area using a NEMA 1 box. Don Re: Junction box w/terminals blocks class 1 div 1 See 501.15 (A). If the box has arcing/sparking devices within it, or has conduits larger than 2" entering it, then seals are required. The box is required to be approved for Cl 1 Div 1 per 501.10 (A)(3).
The customer will connect their control wires at the junction box and run it back to their PLC. I have a couple of field devices that will need seals. Base on the construction of the skid I will like to use a MC cable rated for the area. I would like to use TMCX fittings (rated Class 1 Div. 1) on both ends of the MC cable (and seal the ends).
Class I, Division 1, Group D & Class II, Division 1, Groups E, F, G Junction boxes. I am designing a system that is in a Class I, Division 1, Group D & Class II, Division 1, Groups E, F & G hazardous location. My main panel is x-purged and all the inputs on the machine are intrinsically safe and wiring to isolation barriers in the main panel. When it comes to installing a junction box on a piece of equipment within a CIID2 area, NEMA 4X rated. Which will be used to house only DIN mounted terminal blocks so that there are connection points from the devices on the machine, which would be intrinsically rated sensors and CIID2 rated AC. One is specifically rated NEMA 4X Class 1 Division while the other is just NEMA 4x. My system is going to be used in a Class 1 Division II environment and all the electrical components are Class 1 Division 2. The box without a Class 1 Division 2 rating is considerably cheaper and I was told by someone that I can use the cheaper box.
"Division 1" list: Points 1 & 2 are essentially the same since "repair and maintenance" are normal activities and "leakage" is either normal or it isn't actually Division 1.(It may be Division 2) Point 3 indeed requires a situation that may simultaneously cause a release and a source of ignition. The action must cause both. I have a question on a Class I Division 2 junction box. Here is the following back ground information. We are building a machine that has a NEMA 4X junction box with only terminals. It will be wired using RMC and devices on the machine will be 24 VDC and 4-20 mADC instruments. The customer. Except for luminaires, if ordinary location equipment is otherwise acceptable in Division 2, it does not require any special marking beyond its "ordinary location" identification. Very few local AHJs that know what they are doing would require ordinary junction boxes to be explicitly certified for Class I, Division 2.
