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 single phase 200v from japan use in US with two phase 120v 240V?
No, single-phase 200V from Japan cannot be directly used with two-phase 120V/240V in the US. The voltage and phase differences between the two systems make direct compatibility impossible. A voltage converter or transformer would be needed to convert the electrical supply to match the requirements of the equipment.
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.
Can you lose 240v but not 120v from main power line to house?
Yes, it is possible to lose 240V while still having 120V from the main power line to a house. This can occur if there is a fault or disconnection in one of the phases supplying the 240V circuit, which typically consists of two 120V lines. If one phase is lost, the 120V circuits connected to that phase will be affected, but the circuits on the other phase may still function normally. However, this situation can lead to unbalanced loads and potential issues with appliances.
How do you change over so you can plug a 120V RV plug into a 240V single-phase twist-lock receptacle?
Is the 220V plug 220V only or 110/220V? (The former will have 3 prongs and the former will have 4) If your case is the latter just use the ground, neutral, and one of the hots. This will give you 120V single phase. If the case is the former you can't get 110V off that plug.

What is the role of a transformer in a neighbourhood?
High voltage(23000vac) is delivered to your community then stepped down(240vac 2 phase 120v to neutral) to allow use of common household appliances.

Why are you not getting 240v between the two hot wires?
Because they are "in-phase". In order to get 240v, you need two 120v Alternating Current lines that are 180° out of phase, that is, opposite phases. Only when one line is +120v and the other -120v will you see 240v between the wires.
Can you get 120v single phase from 440 3 phase?
Yes, you can obtain 120V single-phase power from a 440V three-phase system using a transformer. By using a step-down transformer that reduces the voltage from 440V to 120V, you can safely access single-phase power. It's important to ensure that the transformer is correctly rated for the load and that all safety regulations are followed during installation. Always consult with a qualified electrician for any electrical work.
Can you plug 230 volt 60 Hz 4.8 A pump into a household receptical with a GFI breaker?
No. A household receptacle is 120V. It will not work.
How does 120Volts single phase convert to 220Volts 3 phase when the 3 phase voltage should be 208Volts ie 120V x sq route of 3 equals 208V?
If you get 220 volts instead of 208 volts it means that the transformer supplying the circuit is wired in Delta with one of the legs center-tapped to ground.

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.
Can you convert ATX power supply to run off DC input 24v 48v or 120v?
Like to run on a DC powered machine? Probably the easiest and safest way would be to buy a standard power inverter.
How can you get 240V single-phase power from a 240V 3-phase service Can you just connect to two poles of the 240V 3-phase service?
If the 240V 3-phase service is 240V phase-to-phase, then you can get 240V single-phase by simply picking two phases (poles, as used in the question) and connecting the load across them. This is simply one third of a standard delta connection. If you need 120V/240V split phase, i.e. with a neutral, as used in residential services, you will need a transformer. If the service is actually a four wire "quadraplex" service, however, you will probably already have that 120V/240V with neutral connection phase available. In this case, you will need to pick the two phases correctly in order to get the proper 120V service half.
