What are two methods used to switch multiple lighting circuits from different transformers?

The choice of pilot wire and cascading as methods to switch multiple lighting circuits from different transformers is pertinent because both techniques allow for effective control and coordination of lighting in complex systems.

Pilot wire control involves using a dedicated wire that sends signals from a control panel to the individual circuits. This method enables the operator to remotely manage various lighting circuits located at different locations, ensuring precise control over the illumination in multiple spaces without the need for direct wiring between the switches and the lights.

Cascading, on the other hand, refers to the linking of multiple circuits in a manner where an action on one circuit can sequentially affect others. This arrangement allows for a coherent and systematic approach to control lighting, ensuring that when one circuit is activated or deactivated, it can facilitate or influence the operation of subsequent circuits, thereby enhancing the overall efficiency of lighting management.

These methods are especially valuable in situations where lighting needs to be adapted for different scenarios or environments, allowing for versatile setups in large spaces.
