20 Amp ring circuit or Radial?

[hanash2006]

I am having an extension built and the existing fuse box is to be relocated and replaced by a consumer unit.

This will not be completed for 2 weeks and in the meantime I wish to temporarily power two bedrooms in the extension.To facilitate this I was going to utilise the 20 amp fuse which originally was used for the immersion heater, which is now obselete.

The upstairs has been wired in a ring but I was wondering if I should connect it in a radial circuit or connect it in a ring to this 20 amp connection?

The total number of sockets supplied is 13.

20A radial using 2.5mm2
32A ring using 2.5mm2
or
32A radial using 4.00mm
depends what power going to use on sockets

there shouldn't be any problem wiring this ring circuit temporarily to a 20 A fuseway.

it would be sensible to check you have continuity on all conductors of the ring before connecting up in case something has been forgotten, etc.
