A 25mm sq electrical cable is equal to a #4 AWG conductor.

A #4 copper conductor with an insulation factor of 75 and 90 degrees C is rated at 85 and 95 amps respectively.

14 gauge


The above answer is dead wrong. 14 gauge wire can only be used on a 15 amp breaker. You will need AWG 10/2 copper for a 25 amp breaker.

I would use #10. Make sure of separation from other cables of at least one cable diameter. and don't run it embedded in insulation.

Wow! Nobody knows what they are talking about. A 12g wire can carry 25A at 100% capacity. Most would suggest a 10g wire if your doing a new install.
