1 Scope

In order to ensure electromagnetic compatibility (EMC) of electrical and electronic equipment or systems, this section gives connections in electrical and electronic systems and facilities.

Ground and wiring guidelines. It is more concerned with the implementation of grounding and the cables used in industrial, commercial and residential facilities. This section applies to those

Installers of sensitive electrical or electronic equipment and systems and equipment with high emission levels that may degrade the surrounding overall electromagnetic (EM) environment,

Users and manufacturers within a certain range. This section is mainly applicable to new facilities, but it is also applicable to the current situation when economic conditions are feasible.

There are facilities for expansion and improvement.
