Max Power Rating for 800:80 Transformer w/ 120V & 15A CB

  • Thread starter tnkfub
  • Start date
In summary, the conversation revolves around using a transformer with 800 loops in the primary and 80 loops in the secondary, plugged into a 120 V outlet and protected by a 15 A circuit breaker. The maximum power rating of an application that could be used is being discussed, along with questions about the secondary voltage and the placement of the fuse. The desired outcome is to determine the possible maximum current, voltage, and power for the transformer setup.

You are using a transformer with 800 loops in the primary and 80 loops in the secondary . if the transformer is plugged into a 120 v outlet and protected by 15 a cb what is the maximum power rating of an application that could be used ?

Well, then you have misunderstood what PF is about.
Did you read the guidelines?
We do NOT do your homework for you!

So some of the work you could show us to get the ball rolling...

-- Given that turns ratio, what is the secondary voltage? Is it in Vpp or Vrms?

-- Is the fuse usually put in series with the primary or secondary winding? Why?

-- Given the fuse value (what's CB by the way?), what maximum current, voltage and power is possible?
 

FAQ: Max Power Rating for 800:80 Transformer w/ 120V & 15A CB

1. What is the max power rating for an 800:80 transformer with 120V and 15A circuit breaker?

The maximum power rating for this transformer is 120V x 15A = 1800 watts.

2. How do you calculate the max power rating for a transformer?

The max power rating for a transformer can be calculated by multiplying the voltage and amperage of the circuit breaker connected to the transformer. This gives the maximum amount of power that can safely flow through the transformer.

3. Can the max power rating be exceeded for this transformer?

No, it is important to not exceed the max power rating for a transformer as it can lead to overheating and potential damage to the transformer or other electrical components.

4. What is the purpose of the circuit breaker in this scenario?

The circuit breaker is a safety mechanism that protects the transformer and other electrical components from potential damage caused by overloading. It will trip and disconnect the power if the max power rating is exceeded.

5. Is it possible to change the max power rating for this transformer?

The max power rating for a transformer is determined by its construction and cannot be easily changed. If a higher max power rating is needed, a larger transformer with a higher voltage and amperage can be used.
