Rated current is typically defined for all electric devices. Either the device has a rated current, wattage or Volt x amperes (VA). Current can be computed by dividing the wattage or VA rating by 120 volts (For resistive loads). In residential situations the maximum current is governed by the protecting breaker on a circuit. If you all up all the rated currents for devices on a circuit they should be less than or equal to 80% of the protecting breaker current rating.

What is the formula to calculate secondary current?
The secondary current is calculated by dividing the secondary current by the impedance of the load. This value shouldn't exceed the secondary-winding's rated current except for short periods of time.
How do you calculate rated kva of a circuit breaker?
You don't calculate the rated kV.A of a circuit breaker; it's determined by the manufacturer. It's important that a circuit breaker's rated kV.A exceeds the fault level kV.A at the point where the circuit breaker is located, otherwise it may fail to interrupt a fault current and, possibly, self destruct.
How do you calculate the load for a dc panel board?
Summation of individual load connected on the board gives the total load. Power (Load ) = Voltage x rated current.
How do you calculate DG set current?
To calculate the DG set current, you need the load current and the load voltage. To convert it into kilowatts it is divided by 1000.
What is rated normal current?
The rated current is the maximum current that can be drawn in normal continuous use, without any reduction in the lifetime of the device.
What is rated voltage and current in transformers and how to calculate them if given 50k VA?
Rated voltage is the voltage at primary side. Rated current can be found from the equation, Rated Current= Output KVA / Output rated voltage
How do you calculate MVA rating of power transformer?
The product of the secondary rated current and the secondary rated voltage will give you the rated V.A of the transformer.
What is line side amps for 1000kva transformer?
It depends on the voltage on line side. KVA is simply thousand volt-amps, so you need to know voltage in order to calculate amperes.Another AnswerThe rated primary current is the rated apparent power of the transformer, divided by the rated primary current. However, the actual primary current is determined by the actualsecondary load current in proportion to the reciprocal of the turns ratio.
What is the formula to calculate secondary current?
The secondary current is calculated by dividing the secondary current by the impedance of the load. This value shouldn't exceed the secondary-winding's rated current except for short periods of time.
How do you calculate rated kva of a circuit breaker?
You don't calculate the rated kV.A of a circuit breaker; it's determined by the manufacturer. It's important that a circuit breaker's rated kV.A exceeds the fault level kV.A at the point where the circuit breaker is located, otherwise it may fail to interrupt a fault current and, possibly, self destruct.
What is the difference between nominal current and rated current of circit breaker?
They are the same.
How do you calculate dg current?
To calculate the DG set current, you need the load current and the load voltage. To convert it into kilowatts it is divided by 1000.
How do you calculate the load for a dc panel board?
Summation of individual load connected on the board gives the total load. Power (Load ) = Voltage x rated current.
How do you calculate DG set current?
To calculate the DG set current, you need the load current and the load voltage. To convert it into kilowatts it is divided by 1000.
How do you calculate net current assets?
It is current assests minus current liabilites
What is rated normal current?
The rated current is the maximum current that can be drawn in normal continuous use, without any reduction in the lifetime of the device.
How do you calculate Capital requirement?
Current assets - current liabilities
