The amp rating for a 100VA transformer will vary depending on the actual voltage of the transformer. Transformers have both a primary and a secondary voltage.
What else can I help you with?
What is the fuse rating for 5MVA transformer?
50 amp
How many amps is 80VA?
Divide VA rating with the Voltage and get Amp rating. So say you have a transformer that delivers 26V, 80VA, that means a maximum current of 80/26=3.07A for a resistive load.
What is the maximum transformer rating for distribution transformer?
100MVA
What does the power rating of a transformer imply?
Knowing the power rating of a transformer will help an operator use the transformer within its design limitations with regard to heating of the windings and their insulation.
Can you run a 40 amp 10KW oven from a 32 amp 12 KW transformer?
No; drawing more than the rated amperage from a transformer will cause it to overheat.
What is the fuse rating for 5MVA transformer?
50 amp
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.
Will a 4.74 amp transformer fry a computer designed for a 3.42 amp transformer?
No because the current rating of the transformer is a maximum allowable current. If the computer still takes 3.42 amps it will be OK provided the new transformer supplies the correct voltage.
What is the amp rating for a 208 Volt 100 VA transformer?
Is 120 V the primary or secondary voltage? If the primary (input) voltage is 120, then at full load the transformer will draw about 0.42 A from the line, and the current delivered to the load depends on the secondary (output) voltage. If the secondary (output) voltage is 120, then at full load the transformer will deliver about 0.42 A to the load, and the current drawn fom the line depends on the primary (input) voltage. amps = watts / volts So, for instance, if your transformer has a 120 V primary, and a 24 V secondary, as you might find in your AC unit or furnace: Primary current (at full load) - A = W / V A = 50 / 120 A = 0.4166 Secondary current - A = 50 / 24 A = 2.08
Can you use a doorbell transformer with more amps than the original?
Yes, you can use a doorbell transformer with a higher amp rating than the original, as long as the voltage matches the requirements of your doorbell system. The transformer will only provide the current (amps) that the doorbell draws, so having a higher amp rating will not harm the system. However, ensure that the voltage is compatible to avoid damaging your doorbell.
How do you measure the volt ampere rating of a transformer?
Your transformer should have a namplate on it that states how many amps or fractions of amps it can produce. You would then multiply that number by your secondary voltage to get your VA rating. sec. voltage 12v X .05 amp = 12 X .05= .6va
How many amps is 80VA?
Divide VA rating with the Voltage and get Amp rating. So say you have a transformer that delivers 26V, 80VA, that means a maximum current of 80/26=3.07A for a resistive load.
What is the maximum amp rating for a device that is designed to handle a 10-2 amp rating?
The maximum amp rating for a device designed to handle a 10-2 amp rating is 10 amps.
Can you use a 30 amp disconnect switch for a 30 kva transformer?
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.
What is the maximum transformer rating for distribution transformer?
100MVA
What is the KVA rating required of the testing transformer?
Depends on the kva rating of the devices to be tested using a transformer.
Can you sub a 240 volt 1.5 amp transformer in place of a 240 volt 3 amp transformer?
If the load you are connecting to the transformer uses 1.5 amps or less, yes.
