just brought a new built in cooker comes with moulded plug in 1mm cable. rated at max 2400w. taken the old one out and theres 2 6mm cables behind there one going into the hob and one for the cooker. ive chopped the moulded plug off the new cooker and and ratchet crimped the 1mm to the 6mm supply. just wanted to know that its alright basically before i put it back in?
