Marking of Electrical Equipment with Ratings Related to Electrical Supply - Safety Requirements
|Publication Date:||1 June 1994|
|ICS Code (Electrical engineering in general):||29.020|
This International Standard establishes minimum requirements (see note 1) and general rules on marking electrical equipment (see note 2) with ratings and other characteristics to enable the proper and safe selection and installation of electrical equipment related to any supply of electricity.
The object of this standard is to:
- provide general requirements for marking of the characteristics related to any supply system, such as voltage, current, frequency and power without any restrictions;
- provide technical committees with uniform methods for the marking of electrical ratings of products.
This basic safety publication is for general application by relevant technical committees when specifying minimum markings of ratings related to any electrical supply of equipment, sub-assemblies and components. Relevant technical committees may specify additional requirements for the marking of supply characteristics.
