Where are loads typically connected on a transformer?

Loads are typically connected to the secondary terminals of a transformer. This is because the primary terminals are used for connecting the transformer to an input power source, where electrical energy is introduced into the transformer. The transformation process occurs within the transformer, which alters the voltage and current levels based on the turns ratio between the primary and secondary windings.

Once the electrical energy is transformed, it is delivered to the secondary terminals, from which it can then supply power to various loads in the electrical system. Connecting loads to the secondary terminals ensures they receive the correct voltage and current levels suited for their operational needs.

The grounding tabs are designed for safety and protection against faults but are not intended for connecting loads. Additionally, connecting loads directly to the core is impractical as the core serves the purpose of concentrating the magnetic field and does not provide a usable electrical connection. Thus, the correct approach for connecting loads in a transformer setup is through the secondary terminals.
