The amp draw of a MR16 light with a transformer can vary depending on the wattage of the light bulb and the efficiency of the transformer. Typically, a 50 watt MR16 halogen bulb with a transformer can draw around 0.42 amps. It is important to check the specifications of your specific MR16 light and transformer to determine the exact amp draw.
To determine how many 120-volt, 7-amp lights can be run on a 15 kVA transformer, first convert the transformer capacity to watts: 15 kVA equals 15,000 watts. Each light draws 120 volts * 7 amps = 840 watts. Dividing the transformer capacity by the wattage of each light gives 15,000 watts / 840 watts per light ≈ 17.86. Therefore, you can run a maximum of 17 lights on a 15 kVA transformer.
No because that transformer can only supply a ½ amp so it would seriously overheat if a 1-amp load was connected to it.
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.
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.
Using larger wire sizes will not reduce amp draw. The amp draw is determined by the electrical device or load connected to the circuit, not the wire size. Larger wire sizes are used to reduce voltage drop and heat generation in the wiring, but they do not directly affect the amp draw of the circuit.

No, your amp draw will not be reduced. It will actually be slightly higher because the transformer will not be 100% efficient. Contact TEMCo Phase Converters at (800) 613-2290 if you have any more questions.
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.
It depends on the load. A good transformer has over 90% (some as high as 99%) efficiency. So the power drawn by it is a function of the power in the load, plus a small amount due to losses in the transformer.
If the load you are connecting to the transformer uses 1.5 amps or less, yes.
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.
No; drawing more than the rated amperage from a transformer will cause it to overheat.
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.
50 amp
No because that transformer can only supply a ½ amp so it would seriously overheat if a 1-amp load was connected to it.
As your static pressure increases your Amp draw will drop
