To reiterate my point: If he is simultaneously switching on a number
of connected appliances at the wall, only one of which is rated at
something like 4.5 amps draw, then I think there is a fair chance he
is overloading a 5 amp fuse in the main power strip plug. In which
circumstances, provided he keeps the fuses on the individual plugs at
the correct rating there is nothing wrong with him using a 13 amp
fuse on the main plug. That is not to say there is not leakage
somewhere but it is logical to rate the main plug appropriately.

Did the iMac ever turn on without blowing the original(?) 3A fuse?
If it did and now the 3A and 5A fuses blow then there are problems.
The 3A fuse should be more than ample (no pun intended) for the
iMac if that was the original fitting. That is the reason they put
a 3A fuse in. If the current flow was nearly 3A they would put in a
5A.
The fuse ratings are there to ensure the device is safe but that if
anything does go wrong the safety margin is not so great that a lot
of damage would be done before the fuse blows.
The fuse is meant to be the weakest link in the system.
I think there is something else wrong that will need looking into.
If you put in a 13A fuse and it doesn't blow then there is a big
current leakage of some sort, potentially up to 8A, and at 250V
that is a lot of power (2kW) that could be going astray inside your
iMac.
