Introduction
The safety and compliance of an electrical installation are major issues for homeowners looking to renovate or build a home. At MASCOSY Electricité, we support each project with rigor, strictly adhering to current standards and ensuring transparency in quotes. The home electrical installation requires a precise methodology from the initial diagnosis to the final validation. This article details the fundamental steps to follow to guarantee the safety, comfort, and regulatory compliance of your home.
Needs analysis and project preparation
Before any intervention, a thorough analysis of needs is essential. This involves evaluating the configuration of the home, inventorying the equipment to be powered, and anticipating possible developments (extension, home automation, etc.). This step is crucial for correctly sizing circuits, choosing the types of outlets and lighting, and ergonomically positioning control points. MASCOSY Electricité offers a personalized diagnosis, in line with client expectations and in compliance with the requirements of the NF C 15-100 standard, an essential reference for any new or renovated electrical installation (official source).
Creation of the electrical diagram and choice of equipment
The creation of a precise electrical diagram is the next key step. This plan, developed in collaboration with a qualified professional, allows for visualizing all circuits, the distribution of outlets, light points, and the location of the electrical panel. It facilitates the identification of protections to be provided (circuit breakers, differentials) and the compliance with recommended cable sections. The choice of equipment should be made based on their use, robustness, and compliance with current standards. The selected solutions must integrate current needs as well as any future developments of the home (Consuel Guide).
Installation of circuits and electrical conduits
The practical installation begins with the laying of conduits and electrical cables, respecting the layout planned in the diagram. The passage of cables must be done according to the rules of the trade: separation of strong and weak circuits, mechanical protection of cables, clear marking at each end. Particular attention is paid to the section of conductors to avoid overheating or malfunction. Compliance with the provisions of the NF C 15-100 standard is systematically checked, particularly regarding grounding, which is essential to ensure the safety of people and property (ADEME – Electrical Safety).
Installation and connection of the electrical panel
The electrical panel is the heart of the installation. Its size, location, and the quality of the chosen protections play a decisive role in the overall safety of the home. At MASCOSY Electricité, we carry out the installation, renovation, or compliance of electrical panels with rigor and transparency. Each circuit is protected by an appropriate circuit breaker or differential switch, depending on the required sensitivity (20A, 32A, 40A, etc.). We also ensure the balancing of phases for three-phase installations and offer modification or extension of the TGBT to meet the evolving needs of clients (our electrical panel solutions).
Safety, verification, and regulatory compliance
Electrical safety tolerates no approximation. At the end of the work, a complete verification of the installations is necessary: checking equipotential bonding, testing differential protection devices, verifying the absence of insulation faults, and validating compliance with the NF C 15-100 standard. This step is crucial for obtaining the certificate of compliance issued by the Consuel, mandatory during a complete renovation or during the first power-up. MASCOSY Electricité ensures the follow-up of lifting reservations and correcting points noted during real estate diagnostics, thus guaranteeing compliance and peace of mind for homeowners (diagnostic corrections and reservations).
Transparency and support: the electrician quote
The success of an electrical installation also depends on perfect transparency regarding the nature and cost of the work. MASCOSY Electricité is committed to providing a free, clear, and personalized quote, detailing each intervention item, the nature of the equipment, timelines, and the guarantee of compliance. We plan interventions in consultation with our clients, according to their availability, to limit disruptions in their daily lives. This approach of proximity and clarity helps establish a relationship of trust, essential for any technical intervention at home.
Focus: Ensuring electrical safety on a daily basis
Beyond regulatory compliance, electrical safety must be maintained throughout the life of the home. Regular checks, especially when adding new equipment or during renovation work, are strongly recommended. It is also advisable to call on a certified professional for any intervention, to preserve the safety of occupants and the property’s value. Statistics from the National Electrical Safety Observatory further highlight the importance of prevention and maintenance of installations. Indeed, 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 (ONSE report).
