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.
AWG 10.

A 250 MCM copper conductor with a insulation factor of 75 or 90 degrees C is rated at 255 and 265 amps respectively. This conductor can only be load to 80% capacity which allows a working current of 204 and 212 amps respectively. To obtain the full capacity of 250 amps a 350 MCM conductor will be needed. The amp rating for a 350 MCM conductor with an insulation factor of 90 degrees C is 325 amps. 325 x .8 = 260 amps.
A 228 sq mm conductor equates to 450 MCM. A conductor of 450 MCM is not a standard AWG wire size. A standard 400 MCM will carry 380 amps. A standard 500 MCM will carry 430 amps. Difference between 400 and 500 MCM amperage's is 50 amps. Transposing between the two amperage's of 50 amps will be 380 + 25 = 405 or 430 - 25 = 405 amps. This is a very rough calculated answer for the question.
A 0.15Cu cable has a rating of 382 amps summer and 476 amps winter. 0.2Cu allows 425/530 amps. That is for outdoor use in overhead lines.
Amps, or amperes, are a measure of electrical current; ohms are a measure of electrical resistance. Both are widely used in physics.
445 amps. For example Mulberry AAAC cable.
The amperage rating is dependent upon the insulation rating. A pair of 25mm squared wires touching each other are rated at 131 amps. Three 25mm squared wires touching each other are rated at 110 amps.
30 Amps
The 240 sq. mm cable has a diameter of 17.48 mm. It can carry up to 425 Amps current in a duct and up to 520 Amps in open air.
Depends on the type of cable, the method of fixing the cable, the ambient temperature and the way the cable has been run to the motor (i.e in trunking, Conduit) Bascially a cable with a current carry capasity of 2 amps should be fine (1.45 amps with power factor of unity and no de-rating factors). Remember 1mm cable can carry at least 8 amps. Also please improve your English when asking stupid questions!!
Wire size becomes an electrical hazard when it is under rated for the amount of current (Amps or I) it has to carry.Current is the flow of electrons in a circuit. If the current is too large for the cable, the cable will be subject to heating, which is a possible fire hazard.
Amps is short for ampere, a unit for current.
5 amps
30 amps is how much a 10-2 wire will carry at 110 feet. 10 gauge wire is only good for thirty amps per the national electrical code. Using 80% of the breakers usage you will actually be getting only 24 amps.
The electrical current in a circuit is measured in amps.
#6 AWG50sqmm Al cable can carry 60 amps safely up to 150mtrs. If distance increases size should increase
