How much does a secondary distribution box assembly cost

The price of a secondary distribution box assembly typically ranges from $50 to $500 per unit, depending on material, capacity, and features.Typical Price RangeSecondary distribution box assemblies, also known as assembly boxes or distribution boards, vary in cost based on material, amperage rating, number of circuits, and installation type. Standard indoor plastic units for residential use generally start around $50–$100, while metal enclosures with higher durability and industrial-grade specifications can cost $200–$500 or more per unit . Custom or modular designs with advanced features like plug-in MCBs, DIN rails, or weatherproofing may further increase the price .Factors Affecting PriceMaterial: Steel or stainless steel enclosures are more expensive than plastic due to higher mechanical strength and corrosion resistance .Capacity: Rated voltage (120/240V, 240/415V) and current (up to 100A or higher) influence cost .Design Features: Flush or surface mounting, multiple compartments, knockouts, and plug-in MCB compatibility add to the price .Ingress Protection (IP) Rating: Outdoor or high-IP-rated boxes (IP65–IP69K) require better seals and materials, increasing cost .Customization: Special labeling, integrated monitoring, or compatibility with building management systems can raise the price .Supplier ExamplesJUNON V12 Series: Single-phase assembly boxes for residential and light industrial use, made of fireproof plastic or steel, rated up to 100A, typically sold in cartons of 5 units. Prices vary depending on quantity and shipping location, with lead times of 30–45 days for large containers .Panasonic and RS Components: Offer distribution boxes with flexible installation features, dust protection, and shock-proof designs, generally priced higher for commercial or industrial applications due to enhanced durability and safety features .SummaryFor budgeting purposes, residential plastic secondary distribution boxes are usually the most economical option, while metal or industrial-grade assemblies with higher amperage, modularity, or weatherproofing can cost several times more. When selecting a supplier, consider material quality, IP rating, and customization options to ensure long-term reliability and compliance with electrical standards .
