The causes of small power distribution unit fires usually include the following aspects:

Electrical overload: Too many electrical devices are running at the same time, resulting in excessive current in the small power distribution unit and overheating.

Wire short circuit: The wire is aged, damaged or poorly connected, resulting in a short circuit, sparks and fire.

Equipment failure: Failure of an electrical component within the small power distribution unit, such as a circuit breaker, or of the meter itself can cause overheating or sparks.

External factors: such as humid environment or insect and rat infestation, causing damage to the insulation layer of the wires, causing short circuits and fires.

Fire fighting methods:

Cut off power: Turn off main power immediately to prevent the spread of fire and reduce the risk of electric shock.

Use a suitable fire extinguisher: For electrical fires, use a carbon dioxide fire extinguisher or a dry powder fire extinguisher. Do not use a water or foam fire extinguisher to avoid the risk of electric shock caused by conductive electricity.

Maintain a safe distance: Fight fires from a safe distance and avoid contact with live parts.

Alarm and evacuation: Dial the fire hotline quickly, notify professional fire fighters, and evacuate people on site in a timely manner to ensure safety.

By correctly identifying the cause of the fire and adopting appropriate fire extinguishing methods, small power distribution unit fires can be effectively dealt with and risks and losses reduced.
