- An electrical panel is the heart of your home’s electrical system, distributing electricity to different parts of the house. However, older panels may not be able to handle the electrical demand of modern appliances and gadgets. Upgrading your electrical panel ensures that your home’s electrical system operates efficiently and safely, especially if you’ve recently added high-demand appliances or smart home systems. A professional electrician will assess your current panel and recommend an upgrade to avoid potential overloads and improve safety.
