NEMA defines standards used in North America for various grades of electrical Enclosures typically used in industrial applications. Each is rated to protect against personal access to hazardous parts, and additional type-dependent designated environmental conditions. There are 13 Nema type enclosures – with sub categories that are built on specific purpose. Some of which includes for general purpose, weather resistant, water tight, dust tight, submersible, indoor, outdoor, or specific for hazardous conditions.
What to consider in choosing electrical enclosures.
- Location and environment – You must determine where the enclosure will be installed. Is it indoor or outdoor? Will it face a hose down, rain, excessive dust or corrosive elements? It is important to know that if you stick an enclosure under the sun, the internal temperature vs eternal temperature can create huge issues. Determining these factors will guide you toward suitable rating and material.
- Contents – Determine if the prevailing environment around enclosure will damage the equipment within the enclosure unless the equipment is pressurized. You must also consider if the equipment is sturdy or delicate in any respect.
- Size – Determine if you can find a size and shape that meets your needs or if a custom fabricated enclosure is necessary.
