Tips for Choosing the Right Electrical Enclosure

An electrical enclosure is a cabinet or box that protects electrical or electronic equipment. It’s available in both standard and custom styles, made from sturdy materials like mild steel, stainless steel or aluminum. These materials not only offer protection but also prevent electrical shock and electromagnetic interference.

When you work with a reputable electrical enclosure manufacturer like Rockett Inc., you’ll have an expert who will ask the right questions and determine what type of enclosure you need. Many variables are taken into consideration.

Nevertheless, it pays to be informed, so below you’ll find some tips on how to select the right enclosure for your needs.

Codes, Standards and Specifications

Your manufacturer should understand all applicable codes, standards and specifications, including NEMA, the rating system used in North America to determine how an enclosure can withstand certain conditions.

Style of the Box

Electrical enclosures are available in a wide range of styles. The most basic enclosure is called a ‘passive box’ that keeps the interior protected from the exterior. There are also more complicated designs that support hardwired devices like pushbuttons and digital displays.

Some of the most common styles are:

  • Wall-mount
  • Floor-mount
  • Freestanding
  • Consoles
  • Junction boxes
  • Slope top

Ratings and Construction

To make the proper selection, it’s important to know what types of hazards your enclosure must protect against. For example, if your enclosure needs to protect against water, weatherstripping, gaskets, and a drip shield will be help keep the insides dry.

Rockett Inc. specializes in metal enclosures. We have a long experience in building NEMA-style and other metal enclosures.  In many cases powder-coat painted mild steel will hold up to most applications.  Stainless steel; while more expensive, is best suited to the most extreme environments.  Aluminum is another option if overall weight is a concern.
