DEWA Regulations for Electrical Installations - engalaxy

Introduction to DEWA Regulations

The objective of these DEWA regulations is to provide consumers, consultants, contractors,
electrical engineers & technicians with the general guidelines for design, installation,
inspection and compliance with DEWA’s requirements for electric installations,
in order to safeguard persons and property from hazards arising from the use
of electricity.

The regulation however is not intended to substitute detailed
specifications nor to serve as an instruction manual for untrained persons.

It is
essential that all consultants, contractors, electrical engineers & technicians
study and abide by these regulations.

This of course does not absolve the concerned parties from obtaining other necessary approvals from DEWA.

References are generally made to the seventeenth edition of the IET (The
Institution of Engineering and Technology) wiring regulation and International
Electromechanical Commission (IEC) documents.

Consideration has been given to the prevention of fire and shock hazards as well as proper operation and maintenance of wiring installation and equipment.

  • Section 01: GENERAL REQUIREMENTS
