scope:

This Standard applies to assemblies of resistors, enclosures, and other components that provide high impedance grounding for the purpose of controlling the ground fault current or the voltage to ground of an alternating current system, when installed in accordance with the Canadian Electrical Code, Part I.

This Standard applies to neutral grounding resistor assemblies rated for use on nominal voltage systems of 72 kV and less.

Neutral grounding resistor assemblies may be of an open type for mounting in other equipment.

Neutral grounding assemblies may contain components and circuits for sensing and signalling.

In this Standard, "shall" is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the standard; "should" is used to express a recommendation or that which is advised but not required; and "may" is used to express an option or that which is permissible within the limits of the standard.

Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material.

Notes to tables and figures are considered part of the table or figure and may be written as requirements.

Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.
