Harringay, Haringey - So Good they Spelt it Twice!
electrical advice needed
I recently purchased an electric radiator... I am trying to connect it to the fused electrical socket Inside the socket there are two wires - red and black however on the radiator there are for wires 1x blue 1x brown 1x black 1x earth.
My question is does anyone know how I would connect this? Thanks in advance !

This is weird.
First, inside your fused socket there should be an earth wire - usually bare copper, perhaps with green/yellow sleeving.
The blue/brown/black/earth sounds as if the radiator is wired for 3-phase supply. I once came across this when wiring up a German cooker on the Continent but never in the UK.
Where did you buy the heater ? Did it not come with an instruction leaflet ?
I would strongly recommend you get a competent electrician to deal with this - the consequences of getting it wrong are really serious.

Thanks for the advice John.
I purchased the item from Screwfix however I was so excited to install it and use it that I thew the instructions in the dustbin!!!
However after the advice from yourself and Tris I fished them out of the bin and discovered that as Tris advised the extra black wire is actually for an external control/thermostat that can be bought separately. It advises that this wire can be ignored if you have not purchased this item. So that fixes my first problem
hooray Thanks for the advice Tris. (see above)
I forgot to mention that the installation is fairly new (10 years old) and there is an earth wire to the fused spur.
Looks like I will need an electrician - the fused socket used to be for old storage heaters so I'm wondering if the electrics for these heaters are different because even when I ignore the extra black wire and connect the blue wire to the black wire and the red wire to the brown wire and earth to earth the heater does not work

Ok Peter. That clears up a lot.
I don't know if it is still the case but storage heaters used to be fed through a timer so that they charged up overnight on a cheaper tariff ( Economy 7 ) . Your problem may well be that the fused spur only becomes live during the night. You will probably have to get an electrician to bypass the timer and feed the spur from standard rate current.
This will be complicated if you still have other storage heaters that you want to keep in operation.
