6mm2 T&E?

[Chippo1]

2.5 mm2 t & e will be fine as long as it's not buried , buried ok for 17 amps . In free air it's ok for well in excess of 20 amps , 6mm2"would be serious overkill

That's great thanks. I was erring on the side of caution!

Put it this way, your kettle is 2.5-3Kw.....

4mm heat resistant flex would be a far better option. T&E isn't really designed to be used in appliance connections. Although many use it for that purpose.
