Overheating risk: A 13A plug is designed to handle a maximum current of 13 amps, while a 5A socket is only rated for up to 5 amps.
Plugging the higher-amperage 13A plug into the lower-rated 5A socket can cause the socket to overheat, leading to potential fire hazards and socket failure.
Inadequate fuse protection: The fuse in the 13A plug may not be able to provide proper circuit protection if the connected device draws more current than the 5A socket can safely handle.
This increases the risk of damage and fire.
Lack of overload protection: Many 5A sockets may not have adequate built-in overload protection, further exacerbating the risk of overheating and potential hazards.
Potential damage to devices: Connecting a high-power device with a 13A plug to a 5A socket could lead to damage to the device itself, as the socket may not be able to deliver the required current safely.
Electrical safety compliance: Using mismatched plugs and sockets often violates electrical safety standards and regulations, which are in place to protect people and property from the risks of electrical hazards.
