Pressing the doorbell button, a single-pole, single-throw (SPST) pushbutton switch momentarily closes the doorbell circuit. One terminal of this button is wired to a terminal on a transformer. A doorbell transformer steps down the 120 or 240-volt AC electrical power to a lower voltage, typically 6 to 24 volts. The transformer's other terminal ...

The 20 A plug has a blade rotated 90° (opposite blade from what would be the "line" blade on a 2-15 or 5-15 plug. This prevents accidental insertion of plugs into outlets that use different voltages), and the 6-20R receptacle has a T-shaped hole to accept both 6-15P and 6-20P plugs (similar to the 5-20R receptacle accepting 5-15P and 5-20P plugs).
The grounding wire would be diverted around the adapter to reach the faceplate screw above it. However, this ground-wire style of cheater plug was discontinued when it was noted that a loose unattached grounding wire could accidentally become connected to the "hot" blade of a nearby outlet, potentially leading to electric shock. As an ...
The high frequency allows the transformer to be small, which reduces its losses; and the switching regulator can be much more efficient than a linear regulator. The result is a much more efficient, smaller, and lighter device. Safety is ensured, as in the older linear circuit, because a transformer still provides galvanic isolation.
A single-phase wye transformer usually has only one bushing on top, connected to one of the three primary phases. The other end of the primary winding is connected to the transformer case, which is connected to the neutral wire of the wye system and is also grounded. A wye distribution system is preferred because the transformers present ...
