Correspondingly, how many amps can a 6mm twin and earth cable take?

We plan to use our standard 1.5mm twin and earth cable that the manufacturer rates at 20 amps, but the cables are run under thick (more than 100mm) insulation in the loft (installation method 101) so our cables current carrying capacity is reduced to 13 amps (from top table).

Furthermore, how many amps can a 4mm cable carry? 4mm clipped direct has a current rating of 37 amps, all other installation methods drop that rating down below 32 amps.

In respect to this, can I use 6mm cable for a 9.5 kw shower?

9.5kW is either 39A or 41A depending on the voltage it is rated at. 6mm cable is 47A when installed in the most favourable conditions. So 6mm could be used, depending on how it is installed. However it would be usual to use 10mm which would allow the fitting of a higher rated shower either now or in the future.

What size wire is rated for 60 amps?

As the previous poster said, six gauge is the correct wire for 60 A.
