Hooking up the Topaz Isolated Transformer

Like I said in my above post The OP is wiring the xfmr as a step down transformer. Primary of xfmr will be fed from 2 Hot Ungrounded conductors. S1 Must be removed from H4. Period!

Thanks @jea48 corrected my mistake, my bad!
Jim, just for my curiosity, why don’t you recommend OP move S1 to ground terminal? Isn’t the electrostatic shield need to be grounded to divert primary noise to ground?

After thinking carefully, I decided to hire a tech.

Great! Please let us know the result when it is done, where are you going to install the topaz transformer and what will be connected to it?

Hi @ imhififan  

Jim, just for my curiosity, why don’t you recommend OP move S1 to ground terminal?

I did through a PM.

The "tongue test" that people do to see if their 9v batteries still have juice is not recommended.

Thank you Jim,
I am looking for a qualify licensed technician in my area to do the job.
