When performing an instant OFF test, all sources of cathodic protection current must be:
a. Left on except the one closest to the surveyor
b. Interrupted at the same time
c. Set to the same output current level
d. Set to the same output voltage level

Answer (1)

During an instant OFF test for cathodic protection, it is crucial to interrupt all sources of cathodic protection current simultaneously. This allows for accurate measurement of the structure's natural potential without interference. Therefore, the correct answer is that all currents must be interrupted at the same time. ;
