What are the risks of reverse polarity?

Reverse polarity can lead to several risks, including electrical shock, equipment damage, and fire hazards. When electrical devices are connected with reversed polarity, they may not operate correctly, potentially causing short circuits or overheating. Sensitive electronics can be severely damaged, and in some cases, it may create a dangerous situation for users if they come into contact with faulty equipment. Proper wiring and use of polarity indicators can help mitigate these risks.


Is reverse polarity dangerous?

Yes, reverse polarity can be dangerous. In electrical systems, it can cause appliances to malfunction, potentially leading to electrical shocks or fires. Additionally, it may damage sensitive electronic devices that rely on correct polarity for safe operation. It's important to ensure proper wiring and polarity in any electrical setup to prevent these hazards.
