UL 508A Technical Standard
IEC 60364 vs NEC
Machinery Safety in Canada
UL 508A is the reference standard for the Industrial Control Panels in the USA. The basis are the safety rules prescribed by the National Electrical Code (NEC). The NEC has ARTICLE 409 dedicated to the Industrial Control Panels, but it contains few details. That is why in 2001 UL508A was issued. Latest update of the standard is Augusto 2016. UL 508A is applicable to Machinery Electrical Panels only. In case a Machinery has a distribution panel inside (mainly circuit breakers and bus bars, the standard to comply with is UL 891. EN 60204-1 and EN 61439-1 and -2 are the equivalent European Standard, respectively for Control panels and for Power Distribution panels called Switchboards in North America. It is a widespread opinion that in order to design an Electrical Panel in compliance with the North American standards, it is enough that all componentes be Listed or Recognised. In reality that is only one condition. However be aware that, even if a component is Listed it could be used in
The world of electrical installations is not always straightforward. Working on an international project electrical engineers are often bewildered by the extensive amount of electrical standards and wiring regulations which determines their decisions.  The world can be divided in two areas for what concern electrical standards: NEC countries and IEC countries. IEC 60364 is a collection of documents that define fundamental principles, practices, and performance requirements which reflect the European concept of wiring and distribution systems. The NEC is a set of specific rules intended to be used for design, installation, and uniform enforcement of electrical system installations based on North American principles and practices. To be effective, an electrical installation code must be suitable for the existing electrical infrastructure, be suitable for the electrical safety system employed in a country, and be capable of being uniformly interpreted, applied, and enforced. It must
The reference standard in Canada for the Machinery Safety is the Technical Norm Z432-04. This Standard is intended to be applied to newly manufactured and newly installed machinery. The aim of this Standard is to promote a high standard of machinery safety during use.  It specifies requirements for the design, manufacture (including remanufacture and rebuilding), installation, maintenance, operation, and safeguarding of industrial equipment to prevent injuries and accidents and enhance the safety of personnel who operate, assemble, and maintain machinery.
