Power source
Ground connections
Electromagnetic interference

The correct answer is: Field installed wiring

A broken or dotted line on a manufacturer's wiring diagram typically indicates field-installed wiring. This type of representation signifies connections that are not part of the original or factory-installed wiring but are instead added later during installation. Field-installed wiring can be necessary for various reasons, such as meeting specific site conditions, accommodating additional equipment, or customizing the system to conform to local codes and regulations. Recognizing this notation is crucial for anyone working with wiring diagrams, as it helps in understanding the extent of modifications needed for proper installation and adherence to safety protocols.
