ONE OTHER TIP: OPENING A GROUND CIRCUIT DOES NOT CURE A CIRCUIT BREAKER TRIPPING PROBLEM.
Thieves typically target copper wire and cables that run the length of power poles, providing a potential ground circuit for current if equipment fails or live wires fall.
Sensing the ground side at a power supply, for instance, introduces impedance into the ground circuit that causes a host of difficulties with which most engineers are vividly familiar.
The circuit will shut down high voltage in less than 1 ms if leakage in excess of 450 [micro]A is detected through the ground circuit.
The specific technique for installing an isolated ground circuit is not described in the NEC.
And for goodness sakes, opening a ground circuit does not cure a circuit breaker tripping problem.
Common European requirements limit ground circuits from crossing PCB.
They were identified as failures to: test for voltage, ground circuits and/or equipment, follow lockout/tagout procedures, use appropriate technical orders (T.
Currently car com-ponents are tested on vehicles driven for days, weeks, and sometimes months, around tortuous proving ground circuits.
From there, factory-sized and prefabricated multi-conductor extender cables send power to any point under the floor surface, regardless of furniture location or configuration, allowing every square foot of raised floor space the potential to receive convenient power -- including isolated ground circuits and standard power circuits.
