blown fuse

[DARYL]

My 15amp fuse in the main box sometimes blows when I turn on too many appliances. What can Ido about it

Get an electrician in to advise on how the capacity of your fuse box can be increased. Don't put a heavier fuse in - it defeats the object, and you'll burn the house down!

Andy's right.
You need to spread the load of your outlets over two or three fused.  This will probably mean you have to get a new distribution board.
It has to be fitted by a qualified electrician.

You don't need a new distribution board (consumer unit). You can either upgrade the wiring to 4mm and change the fuse (and fuse holder) to 30 A, or for a more simple solution, wire the circuit as a ring main, and fit a 30 A fuse. This is the best solution, find the last socket on the circuit and wire a 2.5mm cable from this back to the consumer unit and connect to the existing cable there. I'm assuming the circuit as it now stands is wired as a serial circuit using 2.5mm cable. Depending on the load/number of sockets on the circuit, you could probably get away with changing the fuse to 20 A, but be cautious of this approach.
