4.1 Schematics
Determining the permissible currents in the various parts of the wiring (whether circuits are made with wires, cables or bars, depending on the currents involved) is linked to the distribution diagram adopted.
If, for conductors reserved for an incoming or outgoing circuit, the calculation is based on the rated current of this circuit, for parts common to several circuits, it may be necessary to adopt reducing coefficients depending on :
the type of distribution adopted ;
the possible choice of diversity factors.
Figure 6 illustrates the various...

Regulations – Standardization
Most of the numerous regulations and standards are now of international origin, some of them EEC directives incorporated into French law, others IEC standards adopted as European EN standards. Among the main ones, there has been an artificial separation between what relates to independent switchgear assemblies and what relates to machine safety (the meaning of which is sufficiently broad to blur the boundary),...
