The flex area coverlays have multiple selective openings exposing the ground circuit
. The films have an electrically conductive adhesive, so, once laminated, the adhesive extends into the coverlay openings and bonds onto the exposed ground, thus grounding out the shield layers.
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.
BESIDESthe ordinary gallops routine, there has been plenty of swimming and a daily 25-minute run round a demanding sand and broken ground circuit
. The first two race-rides were no great conditioners because neither horse was very willing.
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.
