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.
When the continuity of the ground circuit
is interrupted by theft, an alarm is sent to the network operations center, and a text message and email alert are instantly sent to the network manager.
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.
