Myths and truths: Illegal and irregular connections
12/9/25
Clandestine electricity connections are still common in many regions of Brazil and have popular names such as "gato", "macaco" or "gambiarra". All these practices have the same objective: to divert energy without going through the meter or without authorization from the distributor.
"Cat" and "monkey" are the most commonly used terms for direct detour from the electricity grid. A "gambiarra" is an improvised adaptation, often seen at parties and events, when dangerous extensions and connections are used to power tents or sound systems.
Although they may seem like quick fixes, these practices are dangerous, can cause serious accidents and generate losses for the whole community. During festive periods such as São João and Carnival, care must be taken to avoid risks and ensure safety.
Check out the myths and truths below to better understand the impacts, risks and consequences of these irregular connections:
Clandestine connections are safe if done properly.
Myth: There is no such thing as a safe clandestine connection. Even when made by experienced people, irregular connections do not follow technical standards and can cause short circuits, electric shocks, fires and even explosions.
Irregular connections can cause oscillations and power outages.
True. Clandestine connections overload the network, causing voltage variations, frequent drops and oscillations that affect the quality of supply throughout the region.
Altering the meter to reduce consumption is not energy theft.
Myth: Tampering with the meter to reduce consumption is a form of fraud and constitutes energy theft in the same way as a direct "cat" in the network. The practice is illegal, dangerous and subject to the same penalties provided for by law.
Energy theft impacts the entire community.
True. The financial losses generated by clandestine connections are passed on to all consumers, influencing energy tariffs and making bills more expensive for those who pay correctly.
If no one reports it, the irregular connection won't be discovered.
Myth: In addition to reporting, energy companies such as Neoenergia carry out technical analyses, monitor consumption, carry out constant inspections and use technology to identify and correct these practices.
Energy theft is a crime.
True. Energy theft is a crime under the Penal Code (Art. 155) and, depending on the case, can result in a fine, imprisonment and retroactive billing for the energy diverted.
It is not possible to regularize the situation.
Myth: By contacting the distributor, the customer can regularize the electrical installation and avoid major consequences, such as criminal proceedings, fines and safety risks.
Only electricians can make safe connections.
True. All electrical installations must be carried out by qualified professionals and follow the required technical standards. Improvised or clandestine installations pose immediate risks and can lead to civil and criminal liability.
