Building Electrical Services

Electrical services are among the most crucial facility maintenance services, encompassing the implementation and repair of wiring, installation of various sockets, lamps, lighting systems, switches, and electrical devices. These services extend to residential, commercial, and industrial buildings, including telephone systems and electrical equipment.

The maintenance and inspection of electrical equipment are also considered highly important tasks, ensuring the proper functioning and safety of systems.

Recently, network cabling has been added to the scope of electrical services, with some electricians also handling passive network tasks.

In building electrical wiring, safety is a fundamental principle. Ensuring safety minimizes risks to life and property, making it a top priority. Protecting the wiring system is essential to maintain both efficiency and security in electrical installations.

Another significant aspect of this service involves upgrading network levels and addressing infrastructure issues. This requires a thorough and precise assessment of the current network and equipment, followed by evaluating the feasibility and extent of changes needed in terms of technical requirements and associated costs.

Steps of Building Electrical Services

 

1. Electrical Blueprint Design

Preparing and designing an electrical blueprint at the start of wiring and electrical work is crucial for ensuring high-quality results.

2. Measurement and Leveling

Measuring and leveling the positions for switches and sockets, along with marking them, is essential for preparing chiseling and ensuring standard distances.

3. Positioning and Chiseling

Identifying locations and chiseling at the appropriate depth, according to the blueprint, for placing conduits and electrical boxes is the next step.

4. Installing Boxes and Switches/Sockets

Proper installation of boxes and switches/sockets is carried out with attention to guidelines. They must be securely fixed, and the box openings must remain unobstructed during and after installation.

5. Conduit Installation

Installing electrical conduits to carry wires and cables for electricity, telephone, antenna, network, and other systems is performed at this stage.

6. Wiring

Wiring is done to supply electricity from the meter to lamps, sockets, and other appliances. This includes telephone and antenna wiring. The size of the wires is determined by the load, voltage, and amperage requirements.

7. Splicing and Branching

Splicing wire ends, segmenting them, and creating branches within the switch/socket boxes are critical steps that ensure proper distribution of electricity.

8. Installing Electrical Devices

This step involves installing switches, sockets, lamp holders, intercoms, and fuses, followed by testing the electrical setup in residential units. Precision and care are essential to ensure a safe and professional installation.

Essential Tools for Electrical Work

For individuals whose primary work involves electricity or those who aim to work in this field, prioritizing safety and efficiency is crucial. To enhance productivity, speed, and adherence to standards in electrical work, the use of essential tools is necessary. Some of these tools include:

  1. Voltage Tester (Phase Tester): Used to identify live (phase) and neutral wires, and sometimes for tightening or loosening screws.

  2. Wire Cutter: Used for cutting and trimming wires, and occasionally for removing insulation from wires.

  3. Wiring Spring (Cable Puller): A tool designed to guide and pull wires through conduits, especially in complex bends and tight spaces.

  4. Pliers: Utilized for cutting, twisting, and gripping wires during wiring tasks.

  5. Wire Stripper: As the name suggests, it is used to remove insulation from wires to expose the conductive material.

  6. Multimeter: A versatile device for measuring current, voltage, and resistance in electrical circuits.

  7. Measuring Tape: Used to measure lengths, widths, and for accurate placement of electrical components.

Electrical Blueprint Design

Creating an electrical blueprint is the first and most crucial step in building wiring. The design should be tailored to the type of building, wiring system, and desired equipment. The wiring plan must comply with all building wiring standards and be approved by engineering authorities. For convenience, the blueprint highlights the placement of conduits, electrical boxes, panels, and other components.

Placement of Conduits, Boxes, and Electrical Panels

This is one of the most critical stages of wiring. It begins with the construction of walls and continues until the plastering, tiling, or ceramic work is complete. During this phase, wall grooves are cut using specialized grooving tools, and the positions for conduits, electrical boxes, and lighting fixtures are carved out, ensuring full compliance with standards and proper leveling. The conduits, boxes, and panels are then securely placed in their designated spots.

Building Wiring and Electrical Installation

1. Cleaning Conduits and Boxes: Before starting the wiring process, all conduits and especially boxes filled with construction materials must be thoroughly cleaned. Failure to do so can make cable pulling and wiring difficult or even impossible.

2. Wiring: After cleaning, wiring inside the conduits begins. This is a crucial step, especially at connections and terminations. Wires must be joined using appropriate insulators like terminal blocks, heat shrink tubing, solder, or electrical tape. All wires exiting the boxes should be secured (twisted or taped) to prevent accidental removal during construction.

3. Installing Switches, Sockets, and Lighting Fixtures: This is the final step in electrical services and must be executed with precision and care. Proper installation enhances the aesthetics and functionality of the electrical system, satisfying the client. This phase is carried out after all construction work, including painting, tiling, and ceramic installation, is completed. Special attention is given to wire connections to prevent issues such as power outages or fire hazards.

 

Principles of Building Wiring

Building wiring is a technical skill that follows specific scientific principles. While many people believe identifying live and neutral wires is the primary aspect, there are established rules for safe and efficient wiring:

  • Safety First: Electricians must ensure the safety of both the users and the electrical system during installation.
  • Uniform Load Distribution: Wiring should deliver electricity evenly and appropriately to all devices and fixtures.
  • Proper Material Selection: Using suitable cables, wires, and accessories, along with ensuring proper insulation and route planning, is essential.

Electrical Installations in Buildings

Electrical systems in buildings fall under two main categories:

  • Mechanical Installations
  • Electrical Installations

Electrical installations, commonly referred to as building wiring, aim to improve residents' comfort and safety. This includes:

  • Switches: For controlling lights or electrical systems. These include standard light switches and miniature circuit breakers (MCBs), which protect the system from overcurrent.
  • Sockets: Provide power to electrical devices via plugs.

Building wiring must follow a well-designed blueprint tailored to the building's electrical demands and capacity. Adhering to wiring standards ensures optimal system performance and safety.

Key Considerations for Wiring Execution

  1. Understand Electrical Demands: Evaluate the building's current and future power needs and the meter's specifications.
  2. Follow Standards: Use qualified professionals to ensure compliance with safety standards.
  3. Attention to Detail: Proper planning, wiring execution, and safety precautions help prevent long-term issues for residents.

By entrusting electrical wiring to experts, all safety measures and critical wiring standards are implemented, ensuring a safe and efficient electrical system for the building.
