An electrical enclosure refers to a box or cabinet designed to protect electrical or electronic equipment. They also prevent electrical shock. They can consist of rigid plastics or metals like stainless steel, steel, or aluminum.
They see use in a variety of industrial and utility locations, and often protect circuit breakers, control panels, distribution boards, and more.
NEMA types define standards used in North America for different electrical enclosures. NEMA types range from NEMA 1 up to NEMA 13 with varying degrees of protection against environmental hazards. However, each provides a different level of protection, not necessarily in order. For example, a NEMA 12 enclosure measures only a step above NEMA 1 or 2. However, NEMA 4 provides a much larger degree of protection.
E-Box offers enclosures with the following NEMA types:
E-Box offers hinged cover electrical enclosures including single and double door, JIC, or small enclosures. They offer JIC boxes that range in size from 6 x 6 x 4 inches up to 16 x 8 x 14 inches. Their hinged cover enclosures and double door options come in larger sizes.
They also offer double door hinged enclosures with keylocking or padlocking wing knobs for added security.
Both galvanizing and galvannealing are processes of coating a sheet of metal with zinc. They both offer improved strength, corrosion resistance, and durability.
Galvanized steel typically involves a process referred to as ‘hot-dip galvanizing.’ This process involves dipping the steel part into molten zinc to create a coating. Galvanized steel features a shinier appearance than galvannealed steel.
Similar to the hot-dip galvanizing, galvannealing adds an annealing process. The annealing process causes the iron to diffuse out of the steel and into the zinc layer. This forms a zinc-iron alloy layer and makes it stronger and more durable. Galvanneal steel provides a more matte and uniform appearance.
