Question:
Hello Code Friends, I'm working to identify what requirements are needed to have 125 VDC in a cabinet/enclosure for a customer. Can someone please point me in the right direction on where to find this documentation or provide me with these requirements? I'm currently struggling to find documentation on this topic. Thanks, Aaron Dove

Answer:
Hi Aaron and thank you for your question. Article 312 provides guidance/requirements on cabinets, cutout boxes, and meter socket enclosures, and per scope of Article 312 found in Section 312.1 includes installations operating under 1000 Volts.
You may also want to consider Article 409, Section 409.1 and Section 409.100 if the assembly you are building meets the definition of an
Industrial Control Panel found in Article 100.
