The key to finding the right electrical box used to decide first what you will use. Several important factors determine the choice of the right product for you are: the size of housing is necessary, and material selection, finish, and NEMA.
First step: Determining the appropriate size. Electric fencing can vary in size from several centimeters to big events in metal containers and style of the rooms, generators and transformer housings. Decide what style is best for you to choose smaller wall or floor of the largest outdoor enclosures. The total size is ultimately determined by the dimensions of the components inside the cabinet that will be housing. Many users also choose the size based on several factors including the amount of heat generated by electricity and the amount of air flow required subsequential needed to cool the parts. The National Electrical Code (NEC) describes the flow of air and construction requirements based on the amount of heat produced and is a good tool to assist in the selection process.
Step Two: How to determine the appropriate hardware for your cabinet. Custom electrical boxes are typically constructed of carbon steel, stainless steel, aluminum or galvanized steel. Suitable materials for the enclosure depends on the environment is needed for what will be an inch indoor unit can be made from carbon steel and finished with a protective layer base, while an outdoor unit must be stainless steel, aluminum or higher protection. If not constructed of stainless steel or aluminum, alternatively, can be painted or powder coated to ensure it remains resistant to corrosion over time.
Step Three: Select the finish that suits your device. The two main types of finishing options include painting and powder coating. In determining the best finish for your product, follow the instructions below. Painting is a good choice for unique colors and small volumes. The process of painting the enclosures mentioned in the industry as a coating liquid or wet. Powder Coating is an entirely different process of the liquid paint. All powder coating industrial coating is more durable and suitable protection to higher volumes. For corrosive environments, water-facing services are available. Painting and powder coating sheet required to be treated adequately in advance to ensure that the coating to achieve and maintain a good grip. A good grip is important to ensure that the coating does not fade, crack or peel over time. Pretreatment processes or “clean” and preparations often include pressure washing of sheet metal parts with a mixture of phosphate, which effectively removes oil, grease and dust and debris before painting or coating dust.
Step Four: Determine the requirements of NEMA. It is important to determine the rating of good for Nema. If you do not choose correctly, you may end up with damaged components, or you could end up paying big money for the coverage is not necessary. The main factor to consider when choosing the right size for your body is the environment that are included in NEMA 1, 3, 3R, 4, 4X, 7 and 12. These ratings reflect the level of protection against the elements like rain, dust, ice and corrosive agents. Details on each type of qualification and what they mean are:
* For general indoor use: NEMA Type 1
* For the outside, the rain of dust, water resistant, sleet-Tight: 3 Type
* For the outdoor weatherproof rain, sleet resistant, NEMA Type 3R
* For indoor and outdoor, waterproof, dustproof, resistant to hail: NEMA Type 4
* For indoor and outdoor, waterproof, dustproof, corrosion resistant NEMA 4X
* For indoor and outdoor, waterproof, dustproof, corrosion resistant, anti-explosion type 7
* For the interiors, dustproof and drip tight: Type 12
