Lorsqu'un couple de Portland a achet\u00e9 un bungalow des ann\u00e9es 1940, ils \u00e9taient conscients de la n\u00e9cessit\u00e9 de nouveaux placards dans une cuisine et d'un nouveau carrelage dans la salle de bain. Ils ne savaient pas, cependant, que leur projet \u00e9lectrique deviendrait le projet le plus important de la maison. Le syst\u00e8me \u00e9lectrique se composait du tableau \u00e0 fusibles d'origine de 60 amp\u00e8res, et au lieu de prises \u00e0 trois broches, les prises des chambres avaient deux broches, ne fournissant aucune mise \u00e0 la terre. La cuisine ne disposait que d'un seul circuit pour le r\u00e9frig\u00e9rateur, le micro-ondes et le grille-pain. Il a \u00e9galement \u00e9t\u00e9 d\u00e9couvert qu'un propri\u00e9taire pr\u00e9c\u00e9dent avait \u201c am\u00e9lior\u00e9 \u201d le c\u00e2blage dans le garage, en connectant une s\u00e9rie de rallonges aux montants muraux.<\/p>\n

Le r\u00eave du couple d'avoir une cuisini\u00e8re \u00e0 induction, un chauffe-eau \u00e0 pompe \u00e0 chaleur et un chargeur VE dans le garage \u00e9tait d\u00e9sormais absolument impossible sans une refonte compl\u00e8te de l'installation \u00e9lectrique. Ils ne sont pas seuls \u00e0 voir ce r\u00eave bris\u00e9 : chaque propri\u00e9taire, entreprise et gestionnaire d'installation fait face aux m\u00eames difficult\u00e9s lors de la r\u00e9novation d'un b\u00e2timent. Le syst\u00e8me \u00e9lectrique est le syst\u00e8me circulatoire du b\u00e2timent, et si le syst\u00e8me est obsol\u00e8te et d\u00e9fectueux, tout le reste devient pr\u00e9caire. Par cons\u00e9quent, ce guide pr\u00e9sente un ensemble complet d'id\u00e9es sur la mani\u00e8re de r\u00e9aliser une r\u00e9novation \u00e9lectrique \u2014 des mises \u00e0 niveau de s\u00e9curit\u00e9 obligatoires aux extensions de capacit\u00e9 modernes, int\u00e9grations de domotique et r\u00e9novations industrielles, fournissant les estimations de co\u00fbts n\u00e9cessaires, les choix de produits et les recommandations pratiques.<\/p>\n

R\u00e9sum\u00e9 :<\/strong>La r\u00e9novation \u00e9lectrique ne se r\u00e9f\u00e8re pas \u00e0 un seul projet ; il s'agit plut\u00f4t d'une grande vari\u00e9t\u00e9 de mises \u00e0 niveau possibles. Certaines de ces mises \u00e0 niveau concernent des modifications pour la s\u00e9curit\u00e9, telles que le remplacement de quelques prises non fonctionnelles ou l'installation d'un dispositif GFCI dans la salle de bain, tandis que les r\u00e9novations majeures peuvent impliquer la mise \u00e0 niveau compl\u00e8te du service \u00e9lectrique d'un b\u00e2timent, ce qui signifie que tout le tableau \u00e9lectrique, les circuits d\u00e9riv\u00e9s et tous les autres dispositifs devront \u00eatre remplac\u00e9s.<\/p><\/blockquote>\n

The Capacity Renovation: Upgrading for Modern Electrical Loads<\/h2>\n

Panel upgrades rank among the easiest and most common electrical renovations<\/strong> in residential and light commercial properties. An old or obsolete panel can be replaced with an up-to-date 200-amp or larger service panel. The basic reasons for panel upgrades are not new\u2014they include the use of an electric vehicle (EV) charger that requires its own 50-amp service, an electric heat pump that substitutes a gas furnace, an induction range that replaces a gas stove, several computers in a home office, and a workshop with power tools and a dust collector. For a detailed breakdown of the costs, the components, and the three upgrade scenarios\u2014economical, standard, and future\u2011ready\u2014our guide on co\u00fbt de remplacement de panneau \u00e9lectrique<\/a> provides a complete analysis.<\/p>\n

Capacity renovations go beyond panel replacement and might also involve installation of new circuits tailored for appliances that are required by the building. For example, a 50 amp circuit for charging electric vehicles, a 30 amp circuit for heat pump water heater, a 20 amp circuit for a home office or a workshop\u2014each dedicated circuit guarantees availability of full capacity without having to share the breaker with any other load. One dedicated circuit costs from $300 to $800 which depends on length of cable left, ease of the walls and ceiling and circuit\u2019s amperage. Therefore, for homeowners planning to buy an electric vehicle or install a heat pump, implementing dedicated circuits becomes cheaper during large scale renovation project than at later stage as a separate task since all conditions are met already.<\/p>\n

The Smart and Connected Renovation: Intelligence in Every Circuit<\/h2>\n

Optimal electrical remodeling also introduces a convenient transparency and control functionality which is impossible to achieve with conventional panels. There are several contemporary solutions applied for this task. The most essential ones are smart circuit breakers that enable the remote monitoring and controlling of electrical systems, which allows acquiring real-time info about energy consumption, informing about any modifications in current; energy monitoring systems that connect to the panel and provide a full overview of energy consumption within the building as well as mapping circuits consuming the highest amount of energy; smart switches that allow controlling minimal loads remotely and scheduling the operation of the appliances; and load management systems that make it possible for a 200-amp panel to run an EV charger, heat pump and induction cooktop at the same time without overloading the system. For a deeper look at the smart\u2011switch ecosystem and how it integrates with Google Home, our article on works with Google Home smart light switches<\/a> covers the brands, the compatibility requirements, and the installation considerations.<\/p>\n

A smart renovation in a commercial or industrial building includes smart safety tools such as automatic circuit breakers and Residual Current Circuit Breakers (RCBOs)<\/a> that deliver data on electricity quality using a Building management system or SCADA platform. For example, information about electricity consumption allows a building manager to see that a particular motor is consuming more current than is usual, which enables him or her to schedule maintenance before the motor breaks down. Actually, it is the trend of electrical products development nowadays: the smart renovation gives new capabilities to existing distribution boards and the investment in smart devices is an investment in data that modern facility management needs. For a broader look at the trends shaping electrical distribution systems, our article on residential electrical panel upgrade trends<\/a> covers the technologies that are moving from early adoption to mainstream, and the same trends apply to commercial and industrial facilities at a larger scale.<\/p>\n

What an Electrical Renovation Costs\u2014and How to Plan It<\/h2>\n

The cost of an electrical renovation<\/strong> spans a wide range, and the table below provides a practical reference for the most common projects, based on mid\u20112025 pricing in the United States. The costs include labour, materials, and the permit, and they vary by region, by the accessibility of the panel and the wiring, and by the specific equipment selected.<\/p>\n
