Groundwire floating in the breeze


So I bought a pair of interconnects for my turntable rig. Ones with an exposed ground wire. Turns out, attaching the ground wire causes more hum than not attaching. So the ground wire is not connected to anything, and is floating in the breeze, so to speak. Do you think the ground wire floating in the breeze is picking up any RF or other interference? Would I be better off using a pair of interconnects with no exposed ground wire?

I have a grounding wire from my TT interconnects and one from mt TT itself and was told to only us them if there was noise. I have no noise issue so they both just hang in the air.

It would be better for you to tell us what i/c cable you are speaking of?, to be able to help! cheers!
