Your Quick Buying Guide for Electrical Enclosures

Electrical enclosures come in all shapes and sizes. Furthermore, some units are specifically designed to protect internal components from environmental issues such as moisture and gases. This is why choosing the most appropriate type is critical if you hope to adhere to all local and national regulations. We will take a look at some variables that need to be taken into account when purchasing these enclosures. You will therefore have a rough outline of what specific style suits your purposes.

The Type of Mounting

Electrical enclosures can generally be broken down into three main mounting categories. They can be mounted on a wall, a ceiling or a floor. Of course, the exact configuration will depend upon the needs of the internal components (such as a breaker panel as opposed to a junction box). The type of mounting will also revolve around the application of the enclosure itself. For instance, a vehicle repair shop will likely require a different mounting configuration when compared to a junction box found close to a public pool.

The Environment

Electrical enclosures are extremely sensitive to environmental conditions. It is therefore important to address three concerns:

  • How much will the temperature and humidity fluctuate?
  • Are there any specific environmental conditions to address (such as a copious amount of rain)?
  • Will you require a hermetically sealed enclosure to prevent the entrance of potentially harmful gases?

Understanding these metrics will help you select the most appropriate make and model.

Performance Characteristics

The specific ratings of each enclosure is also critical to address. Keep in mind that these are nationally recognised standards and they must be adhered to in order to satisfy all electrical codes. Some units such as Gewiss enclosures are meant to offer superior levels of protection against waters and gases. Other configurations are instead designed to effectively deal with thermal management requirements (such as dissipating heat). If you are uncertain of the appropriate performance characteristics, it is best to speak with a trained professional.

The Material

Electrical enclosures are available in a wide range of materials. These are primarily based around conductive substances (aluminium and stainless steel) and non-conductive alternatives (plastics and fibreglass). Materials are also a concern in regards to the weight of the entire unit once all internal components are installed. There can be times when certain limits cannot be exceeded due to safety reasons, so be sure to take this variable into account. Some lightweight and yet extremely durable options include ABS plastic, polycarbonate, polyester plastic and fibreglass. These substances are also resistant to corrosion, so they will often be employed within harsh environments.

Choosing the correct electrical enclosure is an important step within any project. The good news is that TCAD provides a number of professional solutions.
