Thanks for your electrical question Eddie.

Wye and Delta Electrical Configurations

The Wye and Delta, also described as Y-delta, Wye-delta,  is a mathematical technique to simplify the analysis of an electrical network. The name is given due to the shapes of the circuit diagrams, which look respectively like the letter Y and the Greek capital letter which resembles a Triangle. In the UK  the Wye diagram is also known as a star.
Because the Y and Delta is directly related to the transformation of electricity,  it will also be helpful to see how this is applied at the transformer:

    Hi Gerardo,
    As long as the transformer is rated for the MR11 lamps that you have, there is actually 40 watts to spare so this is within the watt capacity. Keep in mind that transformers do warm up while in operation so they must be installed properly. Always use a transformer or power supply that is recommended by the manufacturer of the light fixture.

    I have an MR11 lamp running on 12 volts and pulling 35 watts. I want to use a transformer with a 120 primary and secondary 12 volts and 75 watts max. Will the transformer heat up?
