What is loop testing?
Loop testing is a quick, convenient and highly specific method of evaluating an electrical circuit for its ability to engage protective devices (circuit breakers, fuses, Ground-fault circuit interrupter).
There are 5 test methods:
• two-wire high-current
• two-wire no-trip with dc injection
• three-wire no-trip
• two-wire no-trip <...
