If an appliance is plugged into an extension lead, and the lead is plugged
into a socket outlet - will a fault in the appliance blow (a) the fuse in
its own lead, (b) the fuse in the extension lead or (c) both?

Is there a general rule of thumb?

The MCB isn't tripping.

(trying to fault find daughters washing machine over the phone, can't get
round till tomorrow pm).

Weeeeeeeellllll....

You would think that the appliance fuse (given that they were the
same type of fuse with the same rating) would go first, but there is
no hard and fast rule that can be applied

No you would not.
There is no reason to expect the appliance fuse to fail before the
extension's fuse.

He obviously thought that one of them would have gone first - that's
why he asked, most people think that the one nearest the fault would go
first. TMH is not someone with the depth of knowledge in such things -
again, which is why he asked
