What are the things to check when renovating the electrical system of your house

When renovating the wiring of a house, it is important to check several elements to ensure the safety and proper functioning of the electrical network.

Here are some things to check:

The condition of cables and electrical wires:

Check the condition of cables and wires for any damage, cracks, or wear. Replace damaged cables to prevent fire risks or short circuits.

Compliance with electrical standards:

Ensure that the electrical installation complies with current standards. Specifically, check for the presence of grounding, differential circuit breakers, disconnectors, etc. These elements are essential to guarantee the safety of the installation.

Understanding the Needs

It seems that the renovation of the electrical panel is necessary to ensure the safety and reliability of your electrical installation. Before starting, it is essential to understand the specific requirements of your house in terms of electrical capacity and safety standards.

Evaluation of the Current Installation

The first step is to assess the current state of your electrical panel. It is recommended to call in a professional electrician to verify the capacities and any faults in your installation. This assessment will determine the necessary modifications to meet your electrical needs.

Planning the New Panel

Once the assessment is complete, it's time to plan the new electrical panel. This step involves determining the number of circuits needed, the size of the panel, and the required protective devices (circuit breakers, differential switches, etc.). Make sure to comply with the standards in your region.

Preparation of Material and Tools

Before starting work, gather the necessary materials: a new electrical panel, appropriate circuit breakers, cables, connectors, and tools such as screwdrivers, pliers, and a voltage tester. Ensure all equipment complies with safety standards.

Power Cutoff

For safety reasons, it is imperative to disconnect the main power supply before beginning work on the panel. This will prevent the risk of electric shock during handling of cables and components.

Installation of the New Panel

Once the power is cut off, start by removing the old panel and install the new one according to the plan. Make sure to respect electrical codes and connect each circuit in an organized and secure manner.

Types of Circuit Breakers and Their Requirements

Circuit breakers play a vital role in electrical safety by protecting circuits against overloads and short circuits. Here are some common types of circuit breakers, with concrete examples of their obligations and applications:

Branch Circuit Breaker

Requirement: The branch circuit breaker is designed to protect individual circuits in a house or building.

Example: A 16A branch circuit breaker is installed on the kitchen electrical circuit to protect outlets used for household appliances such as the refrigerator, microwave, and toaster.

Differential Circuit Breaker

Requirement: The differential circuit breaker detects current leaks and automatically cuts off power to prevent electrocution risks.

Example: A 30 mA type AC differential circuit breaker is installed in bathroom circuits to ensure user safety in case of contact with water.

Molded Case Circuit Breaker (Magnetothermic) (or thermal-magnetic breaker)

Requirement: The moldable case circuit breaker protects circuits against overloads (thermal) and short circuits (magnetic).

Example: A 20A molded case circuit breaker is installed on the living room lighting circuit to prevent overloads caused by too many lamps connected.

Main Disconnector (Linking Circuit Breaker)

Requirement: The main disconnector is installed at the main entry point of the electrical installation to protect the entire network of the building.

Example: A 60A main disconnector is installed at the main electrical panel of a house to protect the entire electrical system against overloads and short circuits.

Hydraulic Circuit Breaker

Requirement: The hydraulic circuit breaker is used to protect power supply circuits in industrial installations against overloads and short circuits.

Example: A high-capacity hydraulic circuit breaker is installed on the electrical circuits of large factories to ensure continuous power supply while avoiding fire and accident risks.

Automatic Circuit Breaker

Requirement: The automatic circuit breaker is used to control and protect electrical circuits in commercial and industrial installations.

Example: A 400A automatic circuit breaker is installed on the main electrical panel of an office building to manage power distribution efficiently and prevent electrical failures.

Each type of circuit breaker has its own specific obligations regarding electrical protection and safety. It is crucial to select the appropriate type of circuit breaker based on the specific needs of each circuit and to comply with local standards and regulations to ensure safety and reliability of the electrical system.

Verification and Testing

Once the installation is complete, carefully check all connections. Use a voltage tester to ensure that each circuit is wired correctly and functions as intended. This step is critical to guarantee the safety of your installation.

Restoration of Power

Once everything is verified and tested, restore the main power supply. Carefully monitor the panel during the first hours to ensure there are no overheating issues or electrical problems. If everything appears to be functioning properly, your new electrical panel is ready to provide reliable power distribution in your home.

By following these steps, you can successfully undertake the complete renovation of your residential electrical panel. Remember that safety is paramount when working with electricity, so do not hesitate to call a professional if you have doubts or questions.

The grounding:

Check that all electrical outlets are properly grounded. Grounding protects people and equipment in case of a short circuit or surge.

Switches and electrical outlets:

Check the proper operation of switches and electrical outlets. Make sure they are well mounted and do not show signs of overheating.

Lighting:

Verify the proper functioning of lighting in all rooms. Replace defective bulbs and ensure fixtures are properly installed.

Household appliances:

Check the compatibility of household appliances with the house's electrical installation. Make sure they are plugged in correctly and do not overload the electrical network.
