220v floor heating whree does my Neutral and Ground wire go?
Hi, Got 220v from fuse box GFI to 22 Cubic Inch PVC gang with 4 pair wire, have thermolstat connection and wires from Floor Heating Mat. I understand that I connect my thermolstat (Red Load Active and Black Load Neutral)to Red and Black floor mat wires (no prob), I attach my thermolstat (Red Power Active and Black Power Neutral )to Red and Black from my 220v 4 pair wire (no prob), I am left with my ground and White Neutral from my 4 pair wire. I think maybe I run a copper ground from a close metal ground into my gang and then connect my copper ground to it (not sure), also what do I do with my Neutral?
Thanks for any help.
Jay

You description is a little confusing. You say 4 pair wires, but I think you mean 3 conductor cable + a ground. Four pairs would be 8 conductors.
240 volt circuits do not need a neutral.
The ground should connect back at the panel where the circuit originates.
Follow up and more info can be given.
And you have fuses and not breakers correct?

I have breakers it is a new house, but once I connect the ground at the panel where does the other end of the ground go - the end that comes to the gang box?
