What size breaker is needed for a 20 kva heat strip?
To determine the appropriate breaker size for a 20 kVA heat strip, you need to calculate the current. For a 240V system, the current is approximately 83.3 amps (20,000 VA / 240V). It’s standard practice to use a breaker rated at 125% of the continuous load, so a 100-amp breaker would be suitable for this application, providing a safety margin. Always consult local electrical codes and a qualified electrician for compliance and safety.
What size main breaker feeding 480v 75 kva transformer?
An exact breaker size can not be given because the voltage, and hence the calculation for current, is not given. A transformer shall be protected by an over current device that is not rated at more that 150% of the primary current.
Size 134 kva cable?
A 134 kVA cable typically refers to the size of cable required for a 134 kilovolt-ampere electrical load. The size of the cable needed will depend on factors such as the length of the cable run, the voltage drop allowed, and the type of insulation and conductor material required to safely carry the current. It is recommended to consult with a qualified electrical engineer or contractor to determine the specific cable size needed for your application.
How many KVA is needed for a 200A panel?
To determine the KVA needed for a 200A panel, you can use the formula KVA = (Voltage x Amperage)/1000. Assuming a standard voltage of 120V, the KVA would be 24 KVA (120V x 200A / 1000 = 24 KVA).
Is 2.8 kva equal to 2800 watts?
Yes, 2.8 kVA is equal to 2800 watts. This is because 1 kVA is equivalent to 1000 watts, so 2.8 kVA would be 2800 watts.

If you have a circuit breaker box containing 650 amps of circuit breakers it is 3 phase 480 volts what size kva generator do you need?
The question isn't the number of amps total on your branch circuits, but rather, what your MAIN breaker(s) are rated at. This will determine what size of generator you will need. And be certain that the generator is 3-phase. <<>> The formula you are looking for is Amps = kva x 1000/1.73 x voltage.
What size main breaker feeding 480v 75 kva transformer?
An exact breaker size can not be given because the voltage, and hence the calculation for current, is not given. A transformer shall be protected by an over current device that is not rated at more that 150% of the primary current.
Would a 15 kva 380 volt generator be big enough to run a house with a 60 amp breaker 380 volts?
A 15 KVA - Generator operating at 380 Volts can cater to only 22.79 Amps. It cannot cater to a 60 Amps breaker
What is the size breaker per phase 200kva generator?
if you have 200 kva so it's 160 KW then ,you need 400 A MCCB and setting at 0.9 and use cable 4c.185 mm2 if the SMDB is nearby and all this will be change according to the ambient temperature and the electrical code used in your area
What is the CB needed for three phase 440V 50Hz at 161 KVA Power?
To determine the required circuit breaker (CB) rating for a three-phase system operating at 440V and 161 kVA, you can use the formula: [ \text{Current (I)} = \frac{\text{Power (P)}}{\sqrt{3} \times \text{Voltage (V)}} ] For 161 kVA at 440V, the current is approximately 210.5 A. It's common practice to select a circuit breaker with a rating higher than the calculated current to account for inrush currents and future expansion, so a circuit breaker rated around 250 A would be appropriate.
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 size breaker should be used for 132 KW submersible pump?
400amper Pumps are not rated in KW. I believe you mean kva, or, most likely in my mind, va. Please clarify what you have for a better answer. If you mean 132 kva, which to many people would mean the same thing as 132 KW, you are talking about a pump that is portable only because it is hauled around on a trailer. But that kind of pump wouldn't be submersible and would most likely not be electric. Motors are not often rated in va either, but if what you meant is 132 va, it will run on any common 15 or 20 amp circuit, assuming you connect it to the right voltage.
What would be the kva for a heat pump?
The kVA (kilovolt-ampere) rating for a heat pump depends on its capacity and efficiency. To calculate the kVA, you can use the formula: kVA = (kW / Power Factor). A typical residential heat pump may range from 3 to 10 kVA, depending on the size and efficiency ratings. It's important to check the manufacturer's specifications for the specific heat pump in question to obtain the accurate kVA rating.
What is the cable size for a 1500 kVA generator with cable length of 50 meters?
