The power panel is responsible for distributing electricity between the rooms in the building and protecting the electrical installation in the event of an overload or short circuit. Despite its presence in homes, apartments and businesses, there are still many doubts about how it works.

Here are some important precautions relating to the maintenance, safety and handling of the equipment:

The switchboard only needs maintenance when it is faulty
 

False: Even if there are no apparent faults, the switchboard needs periodic inspections. The smell of burning, rust, excessive heating and frequent tripping of circuit breakers can indicate problems with the electrical installation.

The resident can reconnect a tripped circuit breaker themselves
 

True. In simple situations, such as an overload caused by the simultaneous use of a lot of equipment, the resident themselves can turn the circuit breaker back on. However, if the device keeps tripping or there are signs of overheating, sparks or a burning smell, it is important to keep the panel de-energized and seek out a qualified electrician.

Circuit breakers trip for no reason
 

False: tripping usually indicates some irregularity in the electrical installation, such as an overload, short circuit or defect in equipment connected to the mains.

Knowing where the power panel is helps in emergencies
 

True. In the event of a short-circuit, a burning smell or electrical maintenance, a fire can help to quickly locate the power board, interrupt the power supply and reduce the risk of accidents. It is important that everyone in the house or property knows where the main power panel is.

Insulating tape solves electrical problems
 

False: Insulating tape can only be used temporarily. Exposed wires, improvised connections and damaged cables need to be repaired properly by qualified professionals.

Old electrical installations require more attention
 

True. Over time, cables and electrical components can wear out naturally. Old wiring, aging circuit breakers and dried-out insulation increase the risk of shocks, short circuits and power outages.

Anyone can change circuit breakers and switchboard components
 

False: The replacement of circuit breakers, cables and other components should only be carried out by trained professionals. Improper handling can lead to serious accidents and damage to the electrical installation.

It is not safe to touch the switchboard with wet hands or feet
 

True. Contact with water significantly increases the risk of electric shock. The power panel should never be handled in damp conditions or with a wet body.

Switching off any circuit breaker cuts the power to the entire property
 

False: In general, each circuit breaker in a power panel is responsible for a specific circuit in the home, such as lighting, sockets or an electric shower. To completely cut off the power to the property, it is usually necessary to turn off the main circuit breaker.

The power panel must remain accessible
 

True. Access to the switchboard must not be blocked by furniture, objects or materials stored nearby. In emergencies or technical assistance, quick access to the equipment is essential.
