Yes, a 30 amp disconnect switch can be used for a 30 kVA transformer. The 30 amp rating refers to the switch's capacity to safely handle 30 amps of current, which is sufficient for a 30 kVA transformer's load. Just make sure to follow the manufacturer's guidelines and electrical codes when selecting and installing the disconnect switch.

How many 200 amp panels can you tap off 250 kva transformer?
You can tap off approximately 833 200 amp panels from a 250 kVA transformer. This calculation is based on dividing the kVA rating of the transformer by the current rating of the panel.
How many amps will a 250 kVA transformer in 220 volts secondary?
To calculate the amperage in the secondary side of a transformer, you can use the formula: Amps = kVA / (Volts x Sqrt(3)). For a 250 kVA transformer with a 220-volt secondary, the amperage will be approximately 660.4 Amps.
How many 240 volt 4.9 amp draw lights can be run on a 15 kva 2 phase transformer?
To calculate the number of lights that can be run on the transformer, use the formula: Power (kVA) = Voltage (V) x Current (A) x √2 x Number of Phases. Rearranging the formula: Number of lights = (Power (kVA) / (Voltage (V) x Current (A) x √2). Plugging in the values: 15 kVA / (240 V x 4.9 A x √2) ≈ 6 lights.
How do you Convert va to kva?
a kva is 1000 vaK is kilo, which means 1000 similar to how a kilometer is 1000 metersTransformers are usually rated in KVA, so a 45 KVA Transformer is a 45 000 VA Transformer
How many amps can you get from a 500Kva transformer?
The amps you can get from a 500 kVA transformer would depend on the voltage of the transformer's output. To calculate amperage, you can use the formula: Amps = Power (kVA) / Voltage. For example, if the output voltage is 480V, you would get approximately 1041 amps (500 kVA / 480V).
Can you use 20 kva transformer in a home?
Yes you could use a 20 kva transformer in a home. Stymied as to why it would be done though. You would need at least a 100 amp service to the home to energize the transformer. Primary side of the transformer would draw 83 amps at 240 volts. If the question was to supply the home, again yes. It would be 100 amp service equipment that the transformer would feed into.
What is the difference between a 1.5KVA and a 3KVA transformer?
The 3 kVA transformer will weigh double the 1.5 kVA transformer.
What is the KVA rating required of the testing transformer?
Depends on the kva rating of the devices to be tested using a transformer.
How do you earth in the 1600 kva transformer?
In 1600 kva transformer we provide NGR (Neutral grounding resistance)

How many 240 volt 4.9 amp draw lights can be run on a 15 kva 2 phase transformer?
To calculate the number of lights that can be run on the transformer, use the formula: Power (kVA) = Voltage (V) x Current (A) x √2 x Number of Phases. Rearranging the formula: Number of lights = (Power (kVA) / (Voltage (V) x Current (A) x √2). Plugging in the values: 15 kVA / (240 V x 4.9 A x √2) ≈ 6 lights.
Why you are indicating capacity of transformer in KVA?
transformer action doesn't depend on power factor that is why we indicate its rating in KVA
What is the result when 3 kva power requirement is being supplied by 250 kva transformer?
The result is that the transformer runs cool and contented. The '250 KVA' rating on the transformer is its maximum ability to transfer power from its input to its output without overheating, NOT an amount of power always running through it. If the 3 KVA load happens to be the only thing connected to the transformer at the time, then only 3 KVA flows into the transformer from the primary line, and only 3 KVA leaves the transformer secondary.

480 transformer to 120 ac current what is the kva on transfomer?
The kVA rating will be listed on the transformer's nameplate, which is usually on the front of the transformer. The 480v to 120v is irrelevant, because many transformers with different kVA ratings convert 480 volts to 120 volts. The kVA ratings can be different and thus affect the rated current through the transformer.
Do the load carried by a transformer is affected by KVA rating?
yah! definately affects, the kva of transformer is suitable for the certain load according to the rating.
Can you change 30 amp to 60 amp?
Changing from a 30 amp circuit to a 60 amp circuit typically involves installing a new circuit breaker, upgrading the wiring, and ensuring that all components can handle the increased amperage. It's important to consult a licensed electrician to assess your electrical system and make the necessary changes to safely accommodate the higher amp rating.
