Always use copper wire. When applied correctly the ground must be wrapped well to
ensure maximum conduction so it can reduce any high frequencies. The copper ground wire
should also be as short and thick as possible

Installer must make sure that the two ends of the ground are well conducted and have
appropriate anti-rust properties.

It is prohibited to use any other device as part of the grounding electric circuit.

