Method
Safety and good practice
Complete protected power system — fully wired reference
Every shown device is connected: primary power, CT/PT measurement, relay output and breaker trip paths all terminate at visible equipment terminals.
Completed reference wiring — follow each colored line terminal to terminalDedicated textbook circuit for this activity
All 12 activities have their own circuit—not a shared generic drawing—with standard symbols, named terminals, individually numbered conductors, distinct wire styles and separated routes.
Detailed test and terminal wiring
Use this terminal-level drawing to build the practical circuit below.
Accessible terminal-to-terminal connection list
The upper drawing explains the complete protected installation. The lower drawing shows one correct practical connection; equivalent wire routing that preserves the same electrical nodes is accepted in Build & Wire.
