Electricians install square D transformers to make it so that a lower electrical voltage is then achieved to an electrical device, even though the power is coming at a higher voltage. One simple example would be an electric doorbell. When Square D transformers are installed in electrical door bells the transformer will take the incoming 100 VAC and convert it down to 12 VAC.
