6.4kw hob circuit

[sidekick]

Customer has himself fitted a new hob of 6.4kw in place of previous gas hob with electric ring x 1 ?
Under the hob there was x 2 sfcu both on there own circuits and both run in 1 x 2.5mm t/e.
He has connected his hob to one of the sfcu fused at 13a and on a 16a MCB at the board.

Using diversity this should do.
However, could he connect both runs of 2.5mm (in theory then 5mm) to a new cooker connection plate and place on 32a mcb covering the max 26.7a of the Hob.
Or is that a No No.

as long as the 2 cables are of equal length ( resistance) and follow the same route, then it's parallel conductors and should be OK. however, a 6mm cable with a cooker isolator and dual outlet pl,ate would be more conventional.

Somebody asked this same question a few weeks ago, but for installing a shower rather than a cooker. Might be worth searching for it, as there were many replies.
