What kind of wiring is inside the building? Types of electrical wiring implementation methods

Correct and principled implementation of electrical installations is one of the most basic stages of construction and renovation of any structure. The exact answer to the question of what kind of wiring inside the building is, determines the road map of sustainability, safety and efficiency of energy consumption of the building. In addition to preventing deadly risks such as fire and electrocution, the standard electrical system increases the lifespan of electrical equipment and ensures the peace of mind of the residents. In this comprehensive guide, we carefully analyze the types of electrical wiring implementation methods and evaluate the engineering requirements suitable for residential, commercial and office structures so that you can make an accurate and economical choice based on national building standards.

The importance and necessity of knowing the types of electrical wiring implementation methods

The electrical network of the building works like the nervous system of a living body that delivers vital energy to all parts. Defects in the design of circuits, failure to use standard conduits and falling into the trap of poor quality material can cause irreparable loss of life and money. Accurate knowledge of the types of electrical wiring implementation methods helps employers, builders, and supervising engineers to choose a method that matches the use of space, available budget, and architectural limitations. Choosing a method that suits the needs of the structure not only reduces future maintenance costs, but also makes possible repairs and troubleshooting a non-destructive and easy process.

What kind of wiring is inside the building?

Generally, in architecture and facility engineering, the answer to the question of what kind of wiring is inside the building is divided into two main categories: surface method and built-in method. In modern urban projects, most of the wiring inside the building is built-in, so that the visual harmony of the environment is preserved and the conductor strands stay away from mechanical damage, moisture and direct contact. On the other hand, the facing method is considered an ideal option for industrial spaces, sheds and old structures that cannot be grooved in their walls. Each of these branches is divided into more specialized technical subcategories that determine the way of connections, piping material and flow distribution method.

A comprehensive review of the types of surface wiring and its applications

Surface wiring refers to a style of circuit distribution in which cables or their protective coverings are installed over the finished surface of plaster, paint, concrete or wood. This system is mainly chosen in cases where the main priority is execution speed, initial economic cost and the ability to constantly change the location of switches and sockets. In industrial workshops, open parking lots and warehouses, this method is used on a daily basis and allows the technician to track down defects as quickly as possible.

Use of duct and trunk in surface wiring

The most common way of implementing the facade circuit in the office and residential sectors is the use of resistant ducts and trunking. Trunkings are plastic or aluminum protective channels with separate compartments, allowing low voltage power cables to pass alongside data network lines without causing noise. These covers have a suitable variety of colors and give a regular effect to the space and prevent the lines from loosening over time.

Wiring with steel and galvanized pipes

In high-risk uses such as engine houses, sheds and public parking lots where there is a possibility of physical shocks, widespread moisture or even chewing of cables by rodents, the use of sealed and galvanized stainless steel pipes is mandatory. These equipments are continuously restrained with special fasteners to the ceiling and wall and provide the ultimate protection against fire and ignition.

Detailed examination of the types of wiring built into the building

Engineers' technical answer to the question of what type of wiring is the most popular inside the building is undoubtedly the built-in method. More than ninety percent of new construction projects use the built-in method because all the equipment, cables and branches are hidden in the thickness of walls, floors or false ceilings. This style guarantees visual beauty, preservation of interior decoration and complete immunity of current-carrying circuits against daily environmental incidents.

Built-in wiring with distribution box (traditional method)

In older structures, a main feed line passed over the top of each room and branched out for lighting and outlets by entering a distribution box built into the height of the wall. Today, due to the difficulty in accessing connections after painting, the reduction of safety coefficients and strict international standards, the use of distribution boxes for residential purposes is almost obsolete and has been replaced by more modular methods.

Built-in wiring with switches and sockets (modern method)

In this advanced technique, the switch boxes and their sockets act as a current distribution base. The power supply wires are inserted directly from the distribution board to the socket and switch boxes, and the wires are terminated inside the same equipment compartment without having to hide under the plastic boxes at the height. Fast access, troubleshooting without destroying the wall, significant reduction of unused wires and tidy appearance are among the best features of this method.

Built-in wiring through the miniature fuse distribution board

The most common modern practice is to centralize the lines in the fuse box or miniature panel of the unit. In this mechanism, every space such as reception, bedrooms, package, air conditioner and kitchen appliances have completely separate power line, phase, neutral and earth. Each circuit is protected with a suitable miniature switch with a certain amperage so that in case of a connection in a consumer, other parts of the building are not deprived of lighting and electricity.

Types of protective pipes in indoor wiring

To implement built-in cabling, wires cannot be buried directly under plaster or cement mortar, because building materials are acidic and corrosive, and they damage the cable sheath due to expansion and contraction. Therefore, knowing the piping material is of fundamental importance in answering the question of what kind of wiring steps are inside the building.

Hard and unbreakable PVC pipes

PVC pipes are hard, self-extinguishing and heat-resistant, and do not catch fire in case of contact with flame. These pipes show extraordinary resistance against the pressure of floor concreting and mechanical shocks, and they create the least friction in the passage of wires. The implementation of these ducts is done with elbows and special adhesives so that no moisture penetrates the conductor circuits.

Polyamide pipes and modern fireproof hoses

Polyamide pipes are widely used in non-load-bearing walls due to their flexibility, ease of installation and cheaper price. Fireproof hose pipes are also present in false ceilings and connecting complex paths, arches and corners. The use of traditional flammable plastic hoses in engineering constructions is completely prohibited today.

Step-by-step steps of building electrical wiring

Observing the order of the wiring steps plays a decisive role in the speed of construction operations and preventing excess costs. First, the technical plan of electrical installations is designed according to the arrangement of devices, lighting and furniture. In the next phase, a precise alignment line is drawn with a leveling hose or laser level to maintain the uniform height of all keys, sockets and panels. Then, the walls are grooved with double-suction devices to prevent the blocks from cracking, and the key and socket boxes are fixed vertically.

Floor and body piping is done along with splinting and initial concreting so as not to damage the tracks. After the completion of the plastering operation and partial drying of the walls, the wiring phase is switched to manual or pneumatic wiring springs. In the last stage, after complete painting, the switches, sockets, caps, lights and distribution board are installed and installed under the supervision of an expert and applying impedance and insulation tests.

Safety standards subject of 13 National Building Regulations

Chapter 13 of the National Building Regulations has formulated all the vital dos and don'ts of all types of electrical wiring implementation methods. One of the fundamental pillars of this standard is the mandatory use of a protective conductor or earth wire throughout the facility. Without the implementation of the earth well and the connection of the earth string to all sockets and metal bodies of electrical appliances, the project will not be qualified to receive the completion of the work.

In addition to the earth wire, it is mandatory to install a life-saving switch or current leakage with a maximum sensitivity of 30 milliamps at the entrance of the residential fuse box supply line so that the imperceptible leakage current that puts a person at risk of death is cut off in a few hundredths of a second. Also, observing the standard distances of the switch and outlet from natural gas pipes, water pipes, sink and finished floor, guarantees the safety of your living space.
