Hi, Blown fuse in my old style house fuse box but i changed it when power was still on!!!?

Question

Please help some one? I had a blown fuse in my old style fuse box, So i changed it, but being a fool i forgot to switch of the mains switch and it sparked as i put it in!!

So is the thing that the fuse goes in to buggered?? Whats it called and how do i replace it??

I appreciate youre time and thank you.

Answer 1

I doubt that you've damaged the fuse-box.

Time to test that fuse.

It may have opened when you tried to insert it.

(Whatever caused the old one to open may still be there.)

With a test lamp or meter: First test from the

'line' side of the fuse holder to ground.

You should get a positive indication.

Then test from the 'line' to the 'load' sides of the

fuse holder. - A positive indication means that:

*there is load, or a short on the line, and

*that the fuse is 'open'.

Note: The sparks when you tried to insert the new

fuse 'power on', indicate that either there was

a load on the circuit, or that the circuit is 'shorted'.

If the later is the case, it's time for a pro.
