What is the reason for frequent blowing of fuse?

There are two conditions that can cause a fuse to blow. First, and most commonly, when too many lights or plug-in appliances draw power from the circuit, it can overload the capacity of the fuse and cause the metal ribbon inside the fuse to melt through.

A true fuse typically consists of a piece of metal, most commonly an encased wire, that actually melts when overheated. This is what stops the fault (aka “short” or “power surge” ).

Can a blown fuse be switched back on?

The breakers reset and can be “switched back on”–so there is no need to replace anything. Much of the time, it’s technically inaccurate to refer to a “blown fuse,” so in this article, we’ll offer you some new concepts and vocabulary to describe your various electrical concerns.
