What type of cable do I need for .....

[garrymum]

Hi

I am wanting to run an extension lead from my plug at the far side of the garage to the front. Rather than buy one that is the wrong length I thought I would buy the cable and a 2 way socket block to power a freezer and a dryer. This way I can have the extension the exact length I require.

What type of cable do I need for the extension?

Thanks

Why use an extension cable? Surely, it would be better to have fixed wiring and socket?

as above, something permanant would be better, but if you still want to go ahead with the extention lead then i'd say 16amp 1.5mm (i think it is) with a RCD breaker plugged into the existing socket would be a safe way round it

I originally wanted to do this and asked on this group if I could run a new socket from the existing one, BUT after more questions from this group it was determined that as the small consumer unit in the garage did not have an RCD it would be better to run an extension cable.

Actually, just re-read my original post about adding a socket and if the garage consumer unit was on the RCD side of the main CU in the house it would be ok. Otherwise I would have to use plug sockets with built in RCD protection. The comment about the extension must have been from another DIY newsgroup somewhere.

i attemped something like this and it was fine but isn't running a freezer and dryer at the same time going to go over 13amp? also you need 1.5mm2 flex.

How do I find out

im not too sure but if its a fairly powerful washer expect a fairly high cost in fuses

What is the rating of the freezer + rating of washer?

1.5mm² cable is rated up to 15A but as already pointed out anything above 13A (3kW) will be a problem.

Hence having it permanently wired.

 

[garrymum]

So, is it the rating in WATTS I need to combine. So, I can't exceed 13A (3 Kw). So, if I add the output in Watts, if it is below 3,000, will I be ok?

 

[luminaire]

Yes.

 

[cheesepuff]

if its below 3100w then its fine

 

[garrymum]

Thanks, so if the combined wattage was over 3100 would I then need to permanently wire in a new socket, in which case I need to check whether the rcd test button trips out the garage.

What is the maximum load a permanently wired socket can take?

13A - in the case of a double socket this is the combined rating of both outlets added together.

If the supply to the garge is not RCD protected why not run a spur in 2.5mm T&E to the freezer from the garge CU power circuit and connect the freezer via a fused spur. Then wire in an RCD socket for the dryer spured of the exisiting circuit.
