I Am about to replace my single oven with a bosch which is rated at 16amp (3.5kw).At present the old oven and hob is on a 32 amp breaker connected via a 6mm cable with 2 separate connection units.Is it Ok to connect the oven 3.5KW and hob which has a total rating Of 6.5kw on the same 32amp breaker or will I need a separate circuit
