What size wire 100 kva transformer?
Wire sizing of a feed conductor is based on the amperage that a device draws. To calculate amperage from KVA a voltage of the supply has to be stated. Without this voltage and whether the transformer is single or three phase an answer can not be given.
Are electric baseboard heaters efficient?
Amps and Watts measure different things. An Amp is a measure of electrical current and a Watt is a measure of Power. Which ever device draws the higher amperage will be the one that uses more electricity! Hence the 240 watt heater draw less amps even though it uses more watts: Volts Watts/Electical Current Amps/Power example heater 240 volt draws 2000/1000 watts - but uses 8.3/4.2 amps example heater 120 volt draws 1500/750 watts - but uses 12.5/6.3 amps
What size wire is used for a 7.5 hp 240 volt single phase motor?
The rule of thumb for a single phase 240 volt electric motor is 7 amps for each horsepower. As this is a 7.5 h.p. motor you should use a 60 amp breaker wired with AWG # 6 copper to be safe.
Why ups rating in ampere hour?
An ups consists of battries as the main components .Batteries store charge (charge=current*time)... hence its units is so. ex. if its rating is 6AH and the load connected to in draws 1A, then the batter lasts for 1 hr.
What size of wire use and breaker for a 30 hp 220 volt 3 phase compressor?
Wire size calculations and breaker sizing are based on the motors amperage. If the amperage is not known the electrical code book rating are used by electricians. The book states that a three phase 30 HP motor draws 80 amps. An 80 amp motor needs a conductor rated at 100 amps. A #3 copper conductor with an insulation factor of 75 or 90 degrees C is rated at 100 and 115 amps respectively. Non time delay fuses rated at 225 amps, time delay fused rated at 125 amps or a breaker rated at 200 amps. These figures can probably be reduced if the actual motors amperage rating is used in the calculation.
What is the Horsepower rating for starter motor?
To determine this you will have to measure the amperage the starter draws when you crank the engine. This amperage times the voltage (12 volts) will give you the wattage. There are 746 watts to 1 HP.
What is the formula for calculating the full current load of a 400 watt metal halide light?
For the amperage of a metal halide fixture look for the nameplate which can be found on the side of the ballast. There it will tell you what the amperage of the fixture draws. Knowing what one fixture draws will allow you to size the lighting circuit for wire and breaker sizes.
How much amperage a 194 series bulb draws?
The 194 bulb is ~3.8 watts, at 14 volts they draw 0.271 amps.
How do you size a phase converter to run a 3 phase welder?
From the nameplate on the welder you find the amperage that the welder draws at the three phase voltage that you are going to use. This amperage is used to size the phase converter. This amperage is also used to size the breaker that will feed the phase converter and wire size for the installation.
How many watts does an electric drill use?
To figure that out you need to know the Amperage that it draws and what the voltage of the circuit is that you're using. Once you know that you can figure out how many watts it uses by doing simple math. Voltage x Amperage = Watts
What size wire 100 kva transformer?
Wire sizing of a feed conductor is based on the amperage that a device draws. To calculate amperage from KVA a voltage of the supply has to be stated. Without this voltage and whether the transformer is single or three phase an answer can not be given.
How many amps does a 1.5 hp dc motor draw?
1 horsepower is equal to 0.7456 kWatts, therefore 1.1184 kWatts will be the power consumption of that motor. The current draw depends on the voltage, simply use the P=UxI or I=P/U formulas to figure out the current draw (P=1118.4 Watts). some voltages: 12Vdc draw 93.2Amps 24Vdc draws 46.6Amps 110Vdc draws 10.17Amps 230Vdc draws 4.86Amps
How do you measure the size of electrical cable for an electric shower?
Wire is sized by the amount of amperage the device to be connected draws. Without this data the question can not be answered.
What kind of wire for double pole for air condition?
The type and size of a wire for a 240 volt air conditioner will depend on the amperage the unit draws.
What does LRA mean in electrical terms?
Locked rotor amperage is the amperage the motor draws when the voltage is first applied to the motor and the rotor has not started to turn. This amperage is usually up to 300% of the motors running amperage. Once the rotor starts to turn the motor generates a back EMF (electro motive force) that opposes the high inrush current. This back EMF drives the amperage down until the motor gets up to its rated speed at which time the motor amperage will be at its run amperage.
What has more power a 5 amp grass trimmer or a 18 volt one?
At a specific voltage the higher the amperage the higher the rated horsepower of the motor. You will see the amperage rating used when manufactures sell hand tools. A saw that draws 12 amps, it is stated, is better than the saw that draws 9 amps. As the question stands a comparison can not be made between voltage and amps.
How many watts will a ballast consume for 3 20 watts tubelights?
Check the ballast for the amperage and multiply it by the working voltage. This will give you the wattage that the fixture draws.
