New Cooker !

[Johnny333]

Before I ask the question, here is the cooker circuit in my house:

32 mcb, 6mm cable to double switch, then 6mm to outlet plate.

New cooker does not state wattage, just specifies 4mm cable.

For this cooker, just wondering is the mcb rating too high and needs to come down to 25A?

No. All is well.

The 6mm² is actually oversized for 32A MCBs.
It's a remnant from 30A rewirable fuses which require larger cable (than 4mm²).

The 6mm² is actually oversized for 32A MCBs.

But is the 4mm² from outlet plate to cooker?

Is it what?
Oversized? No - satisfactory.
From outlet plate to cooker? Yes - it will be.
