What size cable is needed to supply 415v 250 amp three phase fuseboard?
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.
How much current does 300 sq mm cable carry?
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.
What is the cu cable size in 400a load?
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.
What is the current amp of 150sqmm aluminum cable?
445 amps. For example Mulberry AAAC cable.
What area of science uses amps and ohms?
Amps, or amperes, are a measure of electrical current; ohms are a measure of electrical resistance. Both are widely used in physics.
What is ampacity of 25mm cable at 250 volts?
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.
How much current does 20 AWG cable carry?
30 Amps
What diameter is 240 sq mm cable?
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.
How many amps can a 125 mm2 section cable carry?
The current carrying capacity of a cable can depend on factors such as the material, insulation, and installation method. For a rough estimate, a 125 mm2 cable can typically carry around 200-250 amps for standard copper conductors in common installation conditions. It is advisable to consult local electrical codes and standards, as well as a qualified electrician, for precise calculations.
How many amps will a 4 gauge aluminum wire carry?
A 4-gauge aluminum wire can typically carry up to 70-85 amps of current for general household wiring applications. It is important to always consult with local electrical codes and a professional electrician to ensure safe and compliant electrical installations.
How much capcacity of mm size four core cable well be used in running 1kw three faze motor?
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!!
What size cable for 148 amps per NEC?
For 148 amps per NEC, you would typically use a 3/0 AWG copper cable for a maximum voltage drop of 3%. This size cable is rated to safely carry 148 amps while meeting the National Electrical Code (NEC) requirements. It's always best to consult the NEC and a qualified electrician to ensure compliance and safety for your specific application.
When is wire size an electrical hazards?
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.
How many amps for a 0.75mm cable?
5 amps
What size cable for 210 amps?
The recommended cable size for 210 amps would be at least 2/0 AWG (00 AWG) for optimal performance and safety. Make sure to consult the National Electrical Code (NEC) or a professional electrician to determine the exact cable size needed based on the installation requirements and conditions.
What type of cable should be used for a 200 amp service, specifically considering the keyword "ser cable"?
For a 200 amp service, SER cable should be used. SER cable is a type of electrical cable that is suitable for residential electrical installations, including services up to 200 amps. It is a multi-conductor cable with a jacket that is resistant to heat and moisture, making it ideal for use in various applications.
How many amps taken 1 sq-mm copper cable?
Well, isn't that a happy little question! The number of amps a 1 sq-mm copper cable can carry depends on various factors like insulation, temperature, and installation method. It's important to consult a professional electrician or refer to the manufacturer's guidelines to ensure the safe and proper use of your copper cable. Just remember, there are no mistakes, only happy accidents in the world of electrical work!
