Service Details
What is electrical contracting service
Electrical contracting services cover the installation, field implementation, testing and commissioning processes of energy infrastructure in businesses of different scales, from industrial facilities to commercial buildings. This service should not be considered only as assembly work. A correctly planned electrical contracting process ensures that the system becomes safe, orderly, efficient and suitable for operation. For related context, see Electrical Engineering Services and Technical Consultancy.
Correct installation of electrical infrastructure in factories, production facilities, warehouses, shopping centers, hospitals, hotels, business centers and similar buildings is critical for both operational continuity and occupational safety. Mistakes made in electrical contracting applications can lead to problems such as energy interruptions, equipment failures, inefficient operation and high revision costs in the future. For related context, see Electrical Installations Design and Consultancy.
Site survey, load analysis and project compatibility
As Pow-Sys Güç Sistemleri, we handle site survey, needs analysis, load assessment, implementation plan, field assembly, testing and commissioning steps with an integrated approach in electrical contracting projects. During the technical preparation stage before the project, we contribute to establishing the system on the right foundations with LV/MV/HV project design and consultancy service. For related context, see Grounding Installation Periodic Inspection.
Panel assembly, cabling and field implementation
Within the scope of electrical contracting service, power distribution panels, power factor correction panels, MCC panels, control systems, field feeder lines, lighting and socket installations, cable trays, busbar infrastructures, grounding applications and auxiliary power systems can be included in the project. The installed infrastructure can also be supported, when required, by electrical installation periodic inspection and technical inspection processes. For related context, see Periodic Inspection and Periodic Examination Service.
Engineering approach and capacity planning
In a successful electrical contracting application, not only material selection but also the engineering approach is decisive. Cable cross-sections must be determined correctly, panel locations must be planned in an orderly way, protection equipment must be selected appropriately and the system must be planned to allow future expansion. Especially in production facilities, this planning directly affects operational efficiency.
Revision and expansion in operating facilities
Electrical revision and expansion projects carried out in operating facilities require separate expertise. Because when the existing system cannot be completely stopped, power interruptions must be planned in a controlled way, critical loads must be identified and the transition process must be managed carefully. Therefore, electrical contracting service means not only installation but also proper field organization.
LV, MV and transformer-related works
In some projects, the implementation scope does not remain only on the LV side; MV switchgear, transformer connections, power supply infrastructure and protection systems may also be included in the process. For such needs, we can plan our services in an integrated manner with high-voltage maintenance and testing, high-voltage operation responsibility, transformer operation responsibility and transformer services.
Workmanship quality, labelling and maintenance accessibility
The quality of field workmanship in electrical contracting projects plays a major role in the long service life of the system. Orderly panel internal wiring, proper planning of cable routes, complete labelling and correct implementation of connection points both facilitate maintenance and shorten fault intervention time.
Testing, measurement and commissioning
After installation is completed, the testing and measurement stage must be carried out completely. Energizing the system before insulation checks, phase sequence verification, grounding continuity, protection equipment function tests and panel checks are completed can create serious risks. Therefore, technical verification before commissioning is an indispensable part of the electrical contracting process.
Protection coordination and safe operation
Correct operation of protection systems is another subject that should not be neglected in electrical contracting projects. Especially when selectivity and tripping coordination are not designed correctly, a small fault can affect a wider area. At this point, relay and selectivity studies provide a significant advantage for system safety.
Electrical infrastructure suitable for expansion
When receiving electrical contracting service, future needs must also be taken into account. Businesses may invest in new machines, increase production capacity or make changes in field layout over time. Therefore, reserve capacity, spare outgoing feeders, additional panel areas and infrastructure solutions suitable for expansion should be considered during the initial installation phase.
Auxiliary systems and grounding
In some facilities, energy infrastructure must be evaluated together with generators, UPS systems, fire systems and lightning protection solutions. In this case, subjects such as generator inspection services, fire systems periodic inspection and lightning protection periodic inspection can also be included in the overall planning.
Grounding infrastructure is one of the most important safety subjects in electrical contracting applications. An unsuitable or insufficiently designed grounding system can create serious risks for both equipment safety and human health. Therefore, grounding inspection should be considered during system design and verification.

Frequently Asked Questions
What exactly does electrical contracting service cover?
Electrical contracting service covers site survey, needs analysis, project assessment, panel installation, field cabling, power distribution infrastructure, grounding, auxiliary system connections, testing, measurement and commissioning processes. Depending on the project, the scope may also include LV, MV and different auxiliary systems.
For which facilities is electrical contracting service suitable?
Electrical contracting service is suitable for factories, production facilities, warehouses, shopping centers, hospitals, hotels, business centers, commercial buildings and all other facilities where energy infrastructure needs to be installed. It is frequently preferred for new investment, expansion, revision and modernization projects.
What is the difference between electrical contracting and project design service?
Project design service covers the calculation, drawing, technical design and planning stage. Electrical contracting includes the field implementation, assembly, testing and commissioning of these plans. In many projects, these two processes are carried out together with project design and consultancy support.
What determines electrical contracting prices?
Pricing is determined according to facility size, number of panels, cable quantities, site conditions, assembly difficulty, material quality to be used, MV/LV scope and testing-commissioning needs. For a clear proposal, the technical scope and implementation details must first be determined.
Can electrical revision be carried out in an operating facility?
Yes, it can be done. However, in such projects, the power interruption plan, critical loads, production schedule and safety conditions must be considered. With a staged work model, revision can be implemented in a way that affects the existing operation as little as possible.
Why are testing and measurement necessary in electrical contracting projects?
Testing and measurement are necessary to verify that the installed system operates safely and correctly. Energizing the system without insulation, phase sequence, grounding, panel and protection function tests can create fault and safety risks.
Why is grounding important in electrical contracting projects?
The grounding system is critical for safely discharging leakage currents, protecting equipment and ensuring personnel safety. Therefore, after correct design and implementation, grounding inspections are also important.
Can electrical contracting service include the MV and transformer side?
Yes. Depending on the scope of the project, MV switchgear, transformer connections, protection systems and high-voltage infrastructure can also be included in the process. In such cases, integrated work can be carried out with high-voltage services and transformer services.
What does turnkey electrical contracting mean?
Turnkey electrical contracting means that site survey, planning, material supply, assembly, testing, commissioning and delivery processes are carried out within a single organization. This approach reduces coordination losses and allows the process to proceed in a more controlled way.
Is a site survey required before electrical contracting work begins?
Yes. A site survey is required to understand the facility's existing condition, power demand, panel and cable routes, working conditions, production continuity needs and safety risks. A scope and quotation prepared without a proper survey may create missing items or revision needs later.
Can panel assembly, cabling, testing and commissioning be handled within the same scope?
Yes. Depending on the project need, panel assembly, field cabling, cable tray installation, grounding, connection checks, testing, measurement and commissioning can be planned under one scope. This allows implementation and pre-delivery technical verification to be managed in the same process.
How can I get a proposal for electrical contracting service?
To receive a proposal, it is sufficient to share basic information about the facility type, approximate project scope, power requirement and existing infrastructure. After site survey and technical assessment, the scope suitable for the need is clarified and a proposal is prepared accordingly.
