Transformers can be used in either step-up mode or step down mode, they are just as efficent connected either way. Most large transformers have percentage "taps" to allow voltage corrections up or down by about 15%.

What type of transformer is found outside a residential house?
Stepdown Transformer.
What is 660VA for stepdown transformer capacity?
the maximum power it will supply
What kind of transformer do i use to run LED?
A step-down transformer U really don't need a step up or stepdown transformer You need a source capable to run your LED it can be a swithcing power supply for istance a battery
What is the difference between an ordinary transformer and a center-tapped transformer?
An ordinary transformer has two input/output terminals but a center tapped transformer has 2 input and 3 output terminals. One is taken from the center for a ground connection. This causes it to get 50% of the actual value. And ordinary transformer contains 2 windings. An autotransformer has one.
What is transformer tapped secondary?
A 'tap' is a connection made part-way along the length of a transformer's winding. In the case of a standard North American distribution transformer, the 240-V secondary winding is centre tapped and earthed, providing both a 240-V (across the entire secondary) and a pair of 120-V (between each end, and the centre tap) supplies to a building.
What type of transformer is found outside a residential house?
Stepdown Transformer.
Does 110 volts cost more if uses stepdown trasformer?
If you have to pay for the stepdown transformer, yes. If that is provided free, there is a small loss of energy in the transformer, maybe about 5%, and it depends on whether the meter is installed before or after the transformer.
What is 660VA for stepdown transformer capacity?
the maximum power it will supply
What does a step up transformer do at a powerplant?
It is used to step up the voltage in order to transmit it a long distance where it goes into a stepdown transformer and then into your home .
Can a 240V - 110V stepdown transformer be reversed to take a primary load of 180V to secondary 240Volts?
No
What happens if a 208VAC primary voltage is connected to a 240VAC stepdown transformer to 208VAC?
The transformer will act as a step down transformer in the ratio of 240 to 208. This will reduce the 208 input to 180.
How a transformer is very useful in ac supply?
Transformer is the only device which is capable to stepup or stepdown an ac signal. That's why its used widely in ac supply.
Is there a way to install a 120V light on a 277V circuit?
no ----------------------------------------------------------------------------------- Stepdown transformer. More expensive than buying the correct light fixture. Y-THINK-Y

What is the difference between the center tapped transformer and ordinary transformer?
An ordinary transformer has two input/output terminals but a center tapped transformer has 2 input and 3 output terminals. One is taken from the center for a ground connection. This causes it to get 50% of the actual value. And ordinary transformer contains 2 windings. An autotransformer has one.
What is uses of tapped coil?
If question is about a transformer's tapped coil then the taps are a way of getting different voltages from one transformer. The end of the transformer's coil is the common point and the taps to this common point will give different voltages depending on where in the coil the taps are taken from.
Where are center tapped transformers used?
The transformer that feeds your house is a center tapped transformer. Primary 7200, Secondary 240. The 240 volt secondary is center tapped to give you 120 volts on either side of the tap. Hence house voltage is 120 / 240 volts.
