An extension cable can still work even if the fuse is blown, but it’s not advisable as the fuse is a safety feature designed to protect against overcurrent situations. If the fuse is blown, the extension cable may not provide protection from electrical hazards.
An extension cord can work without a fuse, but it increases the risk of electrical hazards such as overheating or short circuits.
Fuses are crucial for protecting the cord and connected devices from these risks.
Some extension cables do have fuses, typically built into the plug or socket.
These fuses are meant to protect against overcurrent situations and provide an added layer of safety.
There could be several reasons why your extension wire is not working, such as a blown fuse, a tripped circuit breaker, a loose connection, or internal damage to the cord itself.
Checking these possibilities systematically can help identify and resolve the issue.
