Can a Pyrolytic Oven use 2.5mm Canke

It depends on the oven’s power rating and manufacturer’s instructions. Generally, a pyrolytic oven often requires a 6mm² cable on its own dedicated circuit due to high current demand. Using 2.5mm² cable may not be safe or compliant. Always check the oven’s installation manual and consult a qualified electrician to ensure the correct cable size and circuit protection. Regards,

Please checkout the wattage of oven. Then divide wattage on voltage which is 230v, after division you will get the value of current, the formula as like I=W/V. Then again check how much current carrying 2.5mm cable on google, keep In mind, the distance and the way the cable run e.g on wall, clipped etc
