Spur from Ring

One other item that may cause concern are hairdryers some of those can have a power of upwards of 2KW.

How much load does it take to blow a 13A 1362 fuse instantaneously?

I have seen hand dryers- 10A each, wired two per fused spur, in a public toilet at the Royal Armoury in Leeds. And they both work together without blowing the fuse!
From the information i could find BS1362 fuses have a fusing factor between 1.25 and 1.75, so a 13A BS1362 could potentially blow between 16.25A and 22.75A.
Good point, I'll put a big label on the hoover plug ... to remind them to unplug their heater while they hoover, alternatively there's a socket in the hall they could use.

Hair dryers ... 2kw ... thats quite a load, its a house of blokes at the moment - so no one has a hair dryer - but we do have girls every so often, again they'll have to unplug their heater or use the hall socket.

Umm, I agree the rating is an issue, but I'll see how I go ... its a toss up between holding someones hand to change a fuse when it blows occasionally or spending a mint having all the wiring rearranged to install radials to the consumer unit, and the disruption - carpets up, beds/wardrobes moved etc. Be a nightmare now the house is occupied ... why did energy costs have to go up so much !""!!
I'll report back in a month, let you know how many times I've had to change fuses - if they cant manage that one their own.
Its a 3 bed semi, roughly how much would a spark charge for wiring up radials from the consumer unit (under stairs), would be 5 rooms to wire up, 2 sockets in each room + Cardmeter (I would supply all cable (4mm cable, consumer unit, sockets etc.).
Just thinking, what would be better - an individual ring to each room or radial with 4mm cable.
