Testing

The documented example was tested for basic electrical operation and wiring integrity.

The rocker switch successfully controlled power to all outlets.

When connected to a properly wired receptacle and switched ON, the green Protection Working indicator illuminated normally, indicating the continued presence of functional surge-protection circuitry.

The red Site Wiring Fault indicator remained unlit during testing.

When switched OFF, both indicators extinguished and power was removed from the outlet bank.

Testing with a receptacle tester confirmed correct hot, neutral, and ground wiring. No open ground, open neutral, reversed polarity, or other wiring faults were detected.

The documented example passed basic outlet-wiring verification and appears fully operational following functional testing.
