Watteredge

What Watteredge does

Watteredge LLC designs and manufactures high-performance copper and aluminum current-conducting equipment for heavy-industrial customers. Founded in 1954 in Ohio and now operating from a 75,000-square-foot facility in Avon Lake, the company builds engineered, custom-fabricated products including bus bars and bus tubes (air- and water-cooled), industrial power cables, flexible braided connectors and laminated copper shunts, electrode arms and holders for electric arc furnaces, and a family of high-current DC switches — most notably a patented vacuum contact module acquired from Westinghouse and proprietary press-welded copper constructions. Products are specified and quoted per project rather than sold off a price list.

Watteredge monetizes through custom hardware sales plus repair, reconditioning and reverse-engineering services, including 24-hour emergency field response for furnace power cables. Commercial motion is sales-led via a nine-person regional team (Eastern/North Western, Midwest, Southern) supported by a global agent network, supplemented by event-driven demand generation (AISTech, The Battery Show) and a technical content/SEO presence. Pricing is quote-based; ITAR registration, DFARS compliance, ISO 9001:2015, and UL listing gate military, defense and many industrial procurement processes.

Customer concentration is spread across more than a dozen verticals — automotive OEM resistance welding, steel mills and EAF operators, chemical and plastics processors, energy and data center operators, telecom grounding, aerospace, medical, metals refining, traction/rail, graphitization, and military — with automotive and steel described as primary segments. The company is owned by Nesco, Inc., which divested it from Southwire in December 2020.

Core offering

Watteredge designs and manufactures high-performance copper and aluminum electrical conduction equipment, including bus bars, bus tubes, water-cooled and air-cooled power cables, flexible connectors, laminated shunts, and high-current DC switches. Products are custom-engineered to specification for industrial applications involving high amperage (up to 250,000 amps) and harsh environments such as steel mills, electric arc furnaces, automotive resistance welding, chemical processing, and telecommunications grounding.

Product overview

Watteredge is a global leader in the design and manufacture of high-performance current conducting equipment, specializing in flexible copper bus systems, power cable assemblies, and high-current switch solutions. The company's product portfolio centers on electrical power distribution components including copper and aluminum bus bars (available as solid bars or in tube form with air or water cooling), industrial power cables (ranging from small to large water-cooled cables and alternate polarity configurations), and industrial flexible connectors (braided connectors, laminated shunts, and insulated cable assemblies). Supporting these core products are high-current switches (disconnect switches, vacuum contact modules and switches in fixed and portable configurations, polarity reversing switches, and SXEW shorting frames), custom fabricated copper products (electrode arms, electrode holders, delta closures), grounding and earthing products for telecommunications and data centers, industrial cable management accessories (straps, slings, wear sleeves), and resistance welding specialty tools (force gauges, cap removers, flash shields, quality test tools). The company operates as a custom fabrication manufacturer offering engineering design, machining, welding, and testing services alongside its product lines, serving industries including automotive, steel, chemical processing, energy, telecommunications, aerospace, medical, and metals refining.
