How do you get 480v circuit from 120v?
To get 480V from 120V, you can use a transformer. A transformer with a turns ratio of 4:1 will step up the voltage from 120V to 480V. Make sure to follow proper safety protocols and consult an electrician if needed.
Formula for 7.5va convert into Amperes load comsumption?
To convert 7.5 VA to amperes, you can use the formula: Amperes = VA / Volts. For example, if the voltage is 120V (typical for household circuits), then 7.5 VA / 120V = 0.0625 amperes.
Can an overhead 400W light with built in ballast that is currently wired to use 480V be rewired to use 120V?
Only if the ballast is a multi tap ballast.:Even if you could install a 120V ballast, or tap it to 120V with the existing one, Current may become an issue. To run the 400W light (sodium?) Now instead of the .833 amp range it's more like 3.33 amps. Supply wiring would have to be able to handle that. Those types of lights are often on long runs to building and grounds lights, parking lots, etc. Using 480 saves a lot on wiring costs.
Can you convert a 30 amp 120V RV receptacle into a normal 120V outlet?
You can, but your circuit will be "protected" by a 30 amp breaker. So you'll have to consider the safety issues of having wiring and appliances that can draw up to 30 amps before tripping the breaker. Will the wiring and circuity support that much current without damage? If not, then switch to a 15 or 20 amp breaker.
37.5 amps converted in watts?
To convert amps to watts, you also need the voltage. The formula to calculate power in watts is Watts = Amps x Volts. If the voltage is 120V, then 37.5A would be equivalent to 4500W (37.5A x 120V = 4500W).
Can you feed a 208v 200amp panel from 480v 20amp circuit?
Not directly, you would need to transform 480v circuit to 120v with a transformer first.
How do you get 480v circuit from 120v?
To get 480V from 120V, you can use a transformer. A transformer with a turns ratio of 4:1 will step up the voltage from 120V to 480V. Make sure to follow proper safety protocols and consult an electrician if needed.
Can you take single phase of 120V with a hot wire and a neutral step up to 480v and then step down to 2 phases of 120V or do you have to input 2 phases of 120v to get 240V out?
Theoretically that can be done with transformers, but the power available would still be limited by the circuit breaker on the original 120 v supply.
What is low voltage transmission?
In the supply industry it refers to circuits of below 1000 volts. Common voltages used are 120v, 208v, 230v, 240v, 277v, 400v, 415v, 480v.
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.
How to convert 120v to 240v for electrical appliances?
To convert 120v to 240v for electrical appliances, you can use a step-up transformer. This device increases the voltage from 120v to 240v, allowing you to safely power appliances that require the higher voltage. Make sure to follow all safety precautions and consult a professional if needed.

How do you power a 480V device from 120V home or kitchen outlet?
A: My advice is do not try it 120 v will require 480v /120 or 4 times the current. assuming 100% efficiency. a transformer can do it but there will be a loss of 20% . House wiring is 15 amps per circuit . So if your whatever unit needs more the 3 amps it just cannot be done. A PWM can also do this job more efficiently but then again the total power is in question.
Can a 480V a 12 ga wire safetly carry 4 x as much power as it would at 120V?
#12 wire will carry about 20 amp 20 X 480 volts = 9600 watts 20 X 120 volts = 2400 watts 4 times.
