Hi Bob,
Sounds like you live in Texas.
Your theory is pretty much correct. I am a professional Engineer, and home
inspector in Texas. The default way to deal with (update) a two wire
circuit is to install a GFCI in the upstream outlet and slave the GFCI to
the downstream outlets. However if there is not a ground available in the
box, you must label the outlet "No Equipment Ground".
I haven't found the Lutron PDF file on their site that I use as reference,
but I found an abbreviated explaination here:
See:
http://www.codecheck.com/250_50_commentary.htmlIts very possible that the center screw and the box may not be grounded. If
it isn't do not connect the ground screw on the outlet to the neutral.
The NEC code is quite confusing. If you need to determine a grounding
method I can look it up, but I am sure its not going to be simple.
If it’s the first floor it might be best to just drive a ground rod into the
earth for your RF and static ground and not wire it directly to the
electrical system.
Regards,
Steve, W2MY
