What is the cable size for 55kw motor on 3 phase?
Without knowing the nominal voltage rating, who can tell? <<>> The sizing of cables or conductors is based on the amperage that the conductor can safely carry. The formula for amperage is I = W/E. Amps = 12000/Volts. With out a voltage stated an answer to this question can not be answered. When you calculate the amperage, re-ask your question for a conductor size for a given amperage.
How do you calculate the size of cable for 1000kw generator?
To calculate the size of cable for a 1000kW generator, you need to consider the generator's voltage and the distance the cable will run. You will need to calculate the current the generator will draw at full load using the formula: Current (A) = Power (W) / (Voltage (V) x Power Factor). Once you have the current value, you can use it to determine the appropriate cable size based on the current carrying capacity of different cable types, factoring in voltage drop considerations for the distance the cable will run.
What size breaker for a 3 phase 460 volt 50 hp motor?
Breakers are sized by the conductors that are connected to them. Conductors are sized by the amperage that the load draws. The electrical code states that a 50 HP 460 volt three phase motor draws 65 amps. The ideal amperage would be taken from the motors nameplate as different motors of the same horsepower will have different amperage's depending on what they are designed to do. The feeders for this motor have to be sized at 125% of the motors full load amperage. 65 x 125% = 81 amps. A #4 copper conductor with and insulation rating of 75 or 90 degrees C is rated at 85 amps. The breaker for this motor is 150 amp or 175 amp fusing or 110 amp time delay fusing.
What is amperage input of transformer on 208 3 phase?
The amperage input of a transformer on a 208V three-phase system can be calculated using the formula: Amperage (A) = Power (Watts) / (Voltage (V) x √3). To determine the amperage, you need to know the power rating of the transformer in watts (or kilowatts). Once you have that, you can plug the values into the formula to find the input amperage.
How do you determine what shade of filter plate is worn for arc welding?

What is the amount of current flow through a wire?
The amount of current flowing through a conductor is governed by the amperage of the connected load. This is why there are different sizes of conductors. Each conductor size is only allowed a specific amount of amperage to flow through it. If the amperage load is higher that what the conductor is rated for then the next larger size conductor has to be used. The limiting of the amperage to specific size conductors keeps the conductor from heating beyond the conductors specifications, under full amperage conditions.
Do you derate for a three phase line and load conductors in the same conduit?
Yes, there will be a de-rate applied to this type of installation. In the electrical code book the amperage rating of conductors is for allowable ampacities for not more than three copperconductors in raceway or cable. This is based on an ambient temperature of 30 degrees C. If the ambient temperature of the conductors where the raceway is installed is over 30 degrees C the conductor amperages have to be reduced. Where the number of conductors are from 4 to 6 conductors in a raceway, the conductors amperage has to be reduced by .8

What regulates amperage in a conductor?
Amperage in a conductor is primarily regulated by the voltage across the conductor and the resistance of the conductor itself, as described by Ohm's Law (I = V/R). When voltage increases, amperage increases, provided the resistance remains constant. Conversely, higher resistance results in lower amperage for a given voltage. Additionally, factors such as temperature and the material properties of the conductor can also influence resistance and thus affect amperage.
Why are conductors needed?
If you want to operate the conductors maximum capacity, the conductor needs the heat, that the amperage produces, to be dissipated. This is why in the electrical code book there are two amperage ratings. The first one is for a free air rating which allows for a high ampacity of the wire. The other rating is for three conductors in a conduit which confines the cooling capacity and so the ampacity rating of these wires is lowered. The same procedure is used in cable spacings in ladder tray networks.
LRA is 134 AMPS. what size breaker should be used?
LRA (locked rotor amps) is not used to calculate the breaker size. Breaker's are used to protect the size of the conductor that is connected to it. Motor calculations are based on the motor's FLA (full load amps).Conductor size is 125% of the motor's FLA.Breaker size is 250% of the motor's FLA.This is the only occasion when the breaker is sized larger that the conductors maximum amperage rating. This is due to the motor drawing up to 300 to 600% of its FLA when starting.If you state the motor's wattage, voltage or amperage this calculation can be calculated here.
What is the amperage of a 20kw heater?
To determine the amperage of a 20 kW heater, you can use the formula: Amperage (A) = Power (W) / Voltage (V). For example, at a standard voltage of 240 volts, the amperage would be approximately 83.3 amps (20,000 W / 240 V). If the heater operates at a different voltage, simply adjust the calculation accordingly.
What is an amperage?
An amperage is the electric current's strength carried by a conductor or machine generated as measured in amperes.
About what percentage measurement difference is there between aluminum vs copper cable through house meter with copper going to circuit panel?
The only difference in the ampacity of the conductors that go through the house meter would be based on the sizing of the conductors. There are two sets of amperage tables in the code book. One is for aluminium conductors and the other is for copper conductors. If the house meter is for example rated for 200 amp distribution, a 3/0 copper conductor rated at 225 amps would be used or a 4/0 aluminium conductor rated at 205 amps would be used. The aluminium conductor is one size larger than the copper conductor.
How thick is the cable to conduct 22.5 kw of power?
Cable doesn't conduct power, it conducts current. Either the voltage and load must be known or the amperage the cable will need to conduct to determine the size of the cable. Once the amperage is known, there are multiple tables online that have cable size and amperage. Do a Google search for "conductor amperage" for examples.
What is the minimum size grounding conductor?
Sizing of ground conductors is based on the load capacity in amps of the generator. There is a table in the electrical code book which states an amperage and what size ground wire that is needed for that amperage.
What AWG wires have the highest current carrying capacity?
The larger the number of the wire, the smaller the amperage that it can carry using the AWG wire identification system.In the electrical trade the smallest building conductor that can be used is a #14 copper conductor with an insulation rating of 90 degrees C and is rated at 15 amps.The largest building conductors that can be used is a 200 MCM copper conductor with an insulation rating of 90 degrees C and is rated at 750 amps.The above ratings are for allowable ampacities for not more than three copper conductors in raceway. For amperages higher than 750 amps the conductors then become paralleled, tripled and quadrupled.There are other ratings for conductors such as free air rating (question for another day) but these are the ones used by electricians on a daily basis
