Introduction
Carrying out or renovating an electrical installation in a house requires method, rigor, and adherence to current standards. Whether your project involves a partial renovation, complete renovation, or new construction, ensuring the compliance and safety of the electrical network is essential for the longevity of your home and daily comfort. At MASCOSY Electricité, we support individuals and professionals in Istres at every step, thanks to certified expertise and total transparency regarding quotes and execution.
1. Preliminary Analysis and Definition of Electrical Needs
Before any intervention, it is crucial to precisely identify your needs. This step involves listing the electrical equipment to be powered (lighting, outlets, household appliances, heating, home automation, etc.) and anticipating potential developments. A diagnosis also allows for checking the state of the existing installation and identifying any non-compliances or obsolescence. Our technicians conduct this personalized study to propose a suitable solution, compliant with the NFC 15-100 standard, which governs the safety of electrical installations in France.
2. Design of the Electrical Diagram and Selection of Suitable Equipment
The design of the electrical diagram determines the distribution of circuits, the location of panels, load balancing, and protection against risks. This step involves choosing certified electrical equipment (panels, circuit breakers, outlets, switches, wiring), all compliant with normative requirements. Prioritizing quality equipment and recognized brands ensures the reliability and durability of your installation. At MASCOSY Electricité, each project benefits from a rigorous selection of professional electrical equipment and precise sizing of protections.
3. Execution of the Installation and Compliance with NFC 15100 Standards
The execution of the work must strictly follow the prescriptions of the NFC 15100 standard, which governs the safety of domestic electrical installations. This includes cable routing, positioning of outlets and switches, installation of protection devices (circuit breakers, differential, surge protectors), grounding, and balancing of electrical panels. A compliant installation significantly reduces the risks of fire and electrocution and facilitates validation by the Consuel during commissioning or property sale. For more details on regulatory obligations, consult the residential electrical safety page on Service-public.fr.
4. Commissioning, Testing, and Compliance Validation
Once the installation is completed, a testing phase is required. This includes checking electrical continuity, verifying the proper functioning of protection devices, measuring grounding, and validating overall compliance. At MASCOSY Electricité, each intervention concludes with a series of tests and a report: this approach ensures our clients complete transparency regarding the quality of the work performed and regulatory compliance. For new or renovated homes, we also assist in preparing the Consuel file guaranteeing the safety of the installation, in accordance with regulations.

6. Safety, Maintenance, and Evolvability of Your Electrical Installation
A reliable electrical installation requires regular maintenance and updates based on evolving usage or technical standards. It is recommended to perform periodic checks, especially when adding powerful appliances or modifying interior layouts. The MASCOSY Electricité team offers installation, renovation, and compliance services to ensure the long-term safety of your installation.

7. The Importance of Standards and Technical Compliance
Adhering to standards allows you to benefit from fully valid home insurance and enhances your property value during a sale or rental. Any intervention must refer to the NFC 15-100 regulation as well as the recommendations of the Quality Construction Agency and the Consuel. Incident reports show that more than 25% of domestic fires in France have an electrical origin, mainly related to outdated or non-compliant installations (source: ONISR, 2022). An installation verified by a professional limits these risks and guarantees the peace of mind of occupants. Moreover, according to the annual study by the Federation of Service Providers to Businesses, in 2026, 67.3% of professional service companies reported an increase in their turnover compared to the previous year.
