When it comes to electrical services in Dubai, residential and commercial landscape demands reliable and secure electrical installations. It would help if you had a firm understanding of the regulations the Dubai Electricity and Water Authority (DEWA) set. Repair Plus, a trusted electrical contractor in Dubai, maintains the highest safety standards. Moreover, they maintain safety and efficiency by abiding by DEWA regulations. Firstly, we will cover wiring, panel installations, and troubleshooting today. Additionally, our guidelines will help individuals and businesses make informed decisions for their electrical needs.
The energy efficiency throughout your premises depends upon the electrical wiring. In other words, Proper electrical wiring is the foundation that prevents overloads. It also contains drop voltage issues. You need to focus on appropriate cable selection. You can also do so by keeping in mind conductor size, load current, and MCB/MCCB ratings. When dealing with concealed wiring, one should always use DEWA-recommended single-core PVC-insulated, non-armored, stranded copper conductors. We will dive into more details later. However, let’s learn about some important things regarding electrical wiring.
Residential and commercial wiring divides into five aspects:
Selection of Cables
As an expert electrician in Dubai, Repair Plus understands the importance of precise electrical work. Thus, we strictly follow the guidelines provided by DEWA for electrical wiring. Indeed, our electrical maintenance company in Dubai is equipped to handle various projects. As a result, our company can handle residential and commercial electrical wiring projects. We adhere to industry best practices. Also, we take into consideration essential factors. Essential factors include electrical load requirements and the optimal selection of cable sizes and types. For example, the table below summarizes the recommended cable sizes for concealed conduit installations. All of this is based on DEWA regulations:
| Size of cables in ‘concealed’ conduits | Max. Rating of MCB/MCCB (A) | Max. Load Current/Demand (A) | |
|---|---|---|---|
| 2 × 1C, 1 phase (mm²) | 3/4 × 1C, 3 phase (mm²) | ||
| 1.5 | 1.5 | 10 | 10 |
| 2.5 | 2.5 | 15 | 15 |
| 4 | 4 | 20 | 20 |
| 6 | 6 | 25 | 25 |
| 6 | 10 | 30 | 30 |
| 10 | 16 | 40 | 40 |
| 16 | 25 | 50 | 50 |
| 25 | 25 | 60 | 60 |
| 35 | 50 | 80 | 80 |
| – | 70 | 100 | 100 |
| – | 95 | 125 | 125 |
| – | 120 | 150 | 150 |
Above are the sizes of cables used in fixed wiring installations for general purposes and in standard situations in Dubai.

Cable Cores Color Identification
This color scheme is for non-flexible cables and bare conductors. Furthermore, it is used for both residential and commercial wiring. It will help in identifying and connecting the correct conductors during installations.
Earth Continuity Conductor
ECC is the key to electrical and grounding safety. Green and Yellow colors identify it.
This conductor serves as the return path for the electrical current. The neutral conductor is identified by its Black color in single-phase and three-phase circuits.
Phase conductors in single-phase circuits typically use the color red for identification. However, different colors are used to differentiate its three different phases. Thus, Phase R is identified by red color, Phase Y by yellow and Phase B is blue in the three-phase circuit.
ECCs are PVC-insulated copper conductors identified by green and yellow colors. They provide a safe path for fault currents. On the other hand, equipotential bonding conductors are essential for minimizing the potential for electric shock.
DEWA stresses the use of a drum-type register. Specifically, the reason is recording and monitoring electrical consumption. People know this drum-type register as a roller cyclometer. It states the slightest requirement of six digits (drums) with a numeral of at least 5mm height, ensuring accurate measurement of energy usage.
Regulations of DEWA mention that C.T.s are devices that measure electrical currents accurately. Current Transformers play an essential role in metering electrical currents—moreover, C.T.s meter electrical currents in low-voltage systems.
Electrical D.B. Panel Installation
An electrical distribution board panel is a vital element of the electrical system. This board acts as a heart for an electrical system. The electrical D.B. Panel distributes electrical power to many circuits. It is a board that contains circuit breakers and switches. Likewise, it includes many other protective devices. It uses all these devices to regulate the flow of electricity.
Hence, Repair Plus, your best electrician in Dubai, handles electrical installation and maintenance of D.B. Panels with utmost care and responsibility.
