4mm hr flex

[yamar1]

just a quick one chaps, need to connect a 6kw domestic cooker, its wired in a 6mm radial on a 32a mcb. i have some 4mm heat resistant flex from work, is it ok to drop to the 4mm cable from the cooker outlet or do i need to stick with the 6mm csa. i work industrial/commercial so just after advice. thanks.

should be fine on 4mm HR. flex. don't forget diversity. doubt it will ever pull more than 20A.

calc came in at just over 26a 6000/230 so 4mm just covers it, thanks for the help

Table 4f3a

4mm flex 32a for normal flex
multiply by 1.09 for 90degree flex
