Electrical Installation CodeApplicability

• Is the code used by construction contractors on a
  local, regional or national basis?
• On a national basis.
• Possible alternative codes that are allowable
• No alternative codes.
• IEC60364 (Electrical installations of
  buildings), other related IEC standards IEEE 141
  Recommended Practice for Electrical Installations
  in Industrial Plants IEEE 241 Recommended
  Practice for Electrical Systems in Commercial
  Buildings are under consideration.
• Types of installations that require the use of
  the code industrial, commercial, residential,
  utility, public, private, etc.
• All types of installations must be in accord with
  the Code.
• New construction only? Or, does it also address
  maintenance?
• The Code is applied to both new construction and
  maintenance work

Electrical Installation CodeMaking Revisions

• How often is the Code updated?
• Formally, annually the Code must be revised. But
  in fact, during last 18 years only several small
  modifications were made.
• Is the time period fixed or variable?
• Fixed. But in fact, the Code is revised only when
  relating policy, equipment, technology are
  changed.
• The code has existed for 18 years. Now its
  necessary to modify the Code so that it will be
  in accord with real situation in power system
  development.
• The main reasons for modifying the Code are
• New electrical equipment has been introduced into
  power system
• New voltage levels have been introduced into
  power system (22kV, 500kV)
• Some safety (electrical fire protection) issues
  need to be revised

Electrical Installation CodeMaking Revisions

• Impact of external/international activities,
  organizations?
• We are looking for international organizations
  that can help us in revising the Code.
• How do organizations and individuals participate?
• A group of experts from different organizations
  (Consultant Companies, Universities,) formed by
  Ministry of Industry and EVN Corp. is responsible
  for preparing the Code.
• Draft of the Code will be circulated around the
  country to experts
• What organization gives final approval?
• Ministry of Industry
• What organization publishes and distributes?
• Ministry of Industry and Electricity of Vietnam
  Corp.

Electrical Installation CodeEnforcement

• What are the penalties of non-compliance?
• Shall be dealt with in accordance with the
  Governments Decree on penalizing administrative
  breaches in electricity area
• Individuals committing breaches of the Code such
  that the breach constitutes a crime shall be
  subject to criminal prosecution and liable to pay
  compensation in accordance with the laws.

Electrical Installation CodeExpectations for the
Future

• New code development process envisioned?
• We intend to develop these projects relating to
  national codes and standards
• Revision of the existing Electrical Installation
  Code
• Revision of the existing Safety Code for
  Exploitation of Power Plant and Electrical
  Network
• Preparations of Technical specifications and
  standards on electrical equipment, including both
  low-voltage and high-voltage levels.
• Preparations of a brand-new National Electrical
  Installation Code
• We hope to co-operate with international
  organizations, especially with NIST.
