Overheating is excessive temperature buildup in wiring or equipment. It does not always require overloading. Overheating can occur due to: Even normal current can cause dangerous heating if resistance increases at connection points. For electrical engineers and M&E contractors, understanding root causes helps develop effective preventive measures, ensuring project. Electrical wiring is designed to carry power safely through a home or business, yet overheating remains one of the most common causes of electrical fires and system failures. This failure mechanism is a serious fire risk, as the insulation's breakdown exposes the copper conductor and can lead to a short circuit. When the power cable passes a certain load current, it will definitely heat up. Loose or Worn Connections One of the most common causes of outlet overheating is loose wiring connections.
