Renewable Energy & Utilities Electronic Enclosures

At A&J Manufacturing Company (A&J), we specialize in the design and manufacture of standard and custom electronic equipment racks and enclosures.

One of the most important things to consider when selecting an electrical enclosure is the NEMA rating, designated by the National Electrical Manufacturers Association. They developed a rating system which determines the types of environments an enclosure can be used in. Our standard enclosures are NEMA 1 and NEMA 12 enclosures which are both intended for indoor use only. They are dust resistant and can withstand damp conditions. They’re also rated NEMA 4 for their water and corrosion resistance.

Our enclosures meet the three most important requirements in the energy and utilities industries:

  • Superior protection for sensitive electronics and components in the harshest conditions
  • Shock & vibration resilience
  • Flexibility with a modular design for easy modifications

Custom Racks for the Energy & Utilities Industries

Electronic components are vital to keeping the services and infrastructure we all rely on running and often requires thousands of measurement devices to provide constant data to various locations.

Key features of our racks include:

  • Rugged design that can withstand extreme conditions
  • High-strength, lightweight aluminum construction
  • Modular structure that requires no welding for assembly/disassembly; offered in a range of sizes, designs and surface coatings
  • Extensive library of accessories and mounting kits

In addition to standard enclosures, we can produce custom equipment enclosures for more complex requirements.

Value-Added Services

Our team is committed to ensuring customers receive the right products for their applications. For example, we help customers design custom solutions that fully meet their specifications and standards by providing engineering assistance. We can also review existing customer-provided drawings and designs to evaluate and/or verify manufacturability, tolerances, materials, finishes, and costs.

Our racks are easily modifiable. We provide kits and accessories that can be used to accommodate whatever electronic component the customer needs to fit within the rack (e.g., drawers, fans, power panels, shelves, and vents).


Electrical enclosures for utility uses come in a variety of sizes, but all require highly effective protection against environmental influences such as humidity, temperature fluctuations and strong vibrations.

  • Metering instrument assemblies
  • Transformers
  • LV motor control centers
  • Radio repeater equipment
  • Control switchgear
  • Pump protection in water and wastewater treatment facilities
