NEC 2020 added transparency to help better identify and understand equipment history

It's common for electrical professionals to source reconditioned equipment – especially where a project requires a quick turn–around on older equipment. The National Electric Code (NEC) is working to assure proper reconditioning of electrical equipment with the new NEC 2020 code requirements. Learn more about what "reconditioned" means and what you can do now given the new requirements.

  • Make safety a priority with authentic breakers

    Molded case circuit breakers are critical to safeguarding people and property. Consistent with our commitment to safety, Eaton strives to help you make well-informed sourcing decisions and avoid unnecessary risks. Eaton does not verify product from non-authorized resellers as being factory direct, and therefore Eaton does not warranty product purchased from these sources. Only an authorized Eaton distributor can provide the Power Of Authenticity.

Eaton's MCCB authentication tool

Eaton’s molded case circuit breaker authentication tool is a web-based application for use with Eaton Series C and Series G molded case circuit breakers. It is intended to provide product specific information and authentication capabilities through a mobile platform.

The risks that counterfeit electrical products pose are threatening to both personal safety and business health. Eaton’s lead in creating awareness and anti-counterfeit technologies and programs is refreshing and will help enhance safety in the electrical industry.
