Controlling a 3 wire AC 120v heater with relay

[jennyfool]

Hi DVDdoug,

Thank you for spotting that! I think you are right, the heater I have is

McMaster-Carr

And it has a brown, a blue and a yellow/green wire. I think they are hot (live), neutral and earth according to this chart:

Do you mean I only need to connect the hot to the relay, the neutral to wall and leave the earth unconnected?

Thanks again!

Best,
