tt ground to phono section. solid copper?

Has anyone experimented with a solid copper line to ground there tt vs stranded. also if I run a ground from my tt to my phono section will I get looping issues if it goes from there to my grounding on preamp? ( the phono is a MF mxvynl ,dc converstion plug two prong  ) I am adding this and no longer going to use my inboard phono section,
Thanks

@jea48 is kind of mostly right.

It's not a safety ground, so practically any gauge will do, but ...when it connects at the phonograph preamplifier's chassis I believe, which in turn should connect to the earth through the preamp's AC plug, when present.

This is another reason why the safety ground on a preamp should never b e disabled.  A lethal voltage could develop at the tonearm or fire created when that wire melts due to an AC short in the preamp otherwise.

Of course, it's very very rare.

Best,

Erik

The equipment ground is not involved.

The Earth does not possess some magical, mystical, power. It does nothing for the SQ of an audio system. Same for the safety equipment ground. The purpose of the equipment ground, when used, is to provide a low resistive path for ground fault current to return to the source neutral conductor.

Yes, and the safety ground is connected to the chassis of the equipment it goes to.  The screw/thread/ground connector next to the turntable input is connected to what, exactly? :-)

Best,

 vpi classic to musical fidelity mxvyl  phono section which has a grounding post next to rca  ( 2 prong dc conv plug for power ) then Rca to my intergrated amp . which also has a grounding post for its onbaord phono section which i was using until now .the mxvynl is new..Thats why i was curious if i should go from mxvynl to intergrated ground ?or it would cause a loop..i am not going to do that and will just roll with a tt to phono ground as per info.
Thanks
