The electrical panel represents the heart of the entire electrical installation of a building. It is the starting point for all the circuits supplying all the rooms in a house. It plays a critical role in powering and keeping devices and occupants safe. It is for this reason that you must ensure that it operates properly throughout the year. But what is the lifespan of this device? What are the different components that make it up and when should it be replaced? Find out the answers in this article.
An electrical panel has many crucial elements that will guarantee the distribution of electricity throughout the house as well as the safety of occupants and devices. Here are the essential components found in an electrical panel.
These are the main components that make up an electrical panel. They ensure the protection of devices in the event of overcurrent or short circuit by automatically cutting themselves off. All you have to do is rearm them to restart the current without having to replace them, unlike fuses. Several types of circuit breakers are available and play a different role.
For example, a thermal circuit breaker protects devices from overcurrent or fire. A magnetic circuit breaker, for its part, is activated in the event of a short circuit and receives a higher current. The magneto-thermal circuit breaker is more complete by fulfilling both the role of the thermal and magnetic circuit breaker.
These are devices that protect the occupants of a house from electric shock. It is necessary to have numerous differential switches installed, since only one does not cover the entire installation. For example, a type A differential switch protects the stove, stovetop, or washing machine.
Another type AC is used to protect lighting and power sockets. The Hpi switch protects large household appliances or computer equipment.
These are devices that protect the entire house from lightning. The lightning rod is installed high up, generally at the top of homes. It draws lightning to the ground, which protects occupants and devices from a violent discharge. The surge protector, for its part, is installed in the electrical panel and channels the overvoltages generated by lightning. This saves electrical installations.
It is a device that will automatically manage the power supply to home devices according to power needs. For example, if you use an electric stove in winter, the load shedder will temporarily turn off the heaters to give full power to the stove.
The load shedder is practical in that you can save money on your bills. Indeed, you can subscribe to a subscription that is undersized compared to your normal consumption, and juggle the use of devices to find the necessary power whenever the need arises. This device may be cascading, cyclic, or a combination of both. The first type cuts off the power to the electrical circuits in a predefined order, while the second does so alternately, in a rotating manner. The third is a combination of the other two types.
This device installed in the electrical panel makes it possible to operate certain devices at well-defined hours. Generally, the off-peak switch is used by those who opt for an off-time/peak subscription type.
Thus, you can program to use only devices that consume a lot of electricity only during off-peak hours, especially at night. This allows you to save money on your bills. Of course, this device is designed in such a way as to interrupt this function and to let the devices work in case of urgent need in non-peak hours.
Determining the exact lifespan of an electrical panel is difficult. It depends on various factors such as the brand and the quality of the components included in the table. But in general, the lifespan of an electrical panel is between 20 and 30 years.
For up to 20 years, you can be confident about the reliability of the device. Between the ages of 20 and 30, you should schedule more frequent inspections and maintenance. You should anticipate a full replacement between this age range.
There are several reasons why you should replace your electrical panel well before the end of its life. Here are the main ones.
When buying a house that was already inhabited before, it is advisable to replace the electrical panel without delay. Indeed, it is difficult to know the age and condition of the components found there. For greater safety, it is best to replace it in its entirety to avoid possible problems when you occupy the house.
If you have an old building, its electrical panel must also date. Most older homes have fuse panels that are outdated. For greater safety, it is imperative to replace it with a more modern electrical panel equipped with circuit breakers.
Over time, you have to buy new household appliances. Your power needs automatically increase with the number of new devices. At some point, your electrical panel is no longer able to deliver that power. You must then replace it if it is not modular.
Standards on electrical panels evolve regularly in order to guarantee the safety of occupants and devices in a building. So, even if you have a fairly recent table, it is possible that it no longer meets the latest standards in force. Thus, an upgrade must be carried out by changing some elements or by replacing it entirely if necessary.
