Hello Glen,

Be careful about connecting your house ground to your RF ground.  You 
could end up frying electrical equipment and appliances throughout 
your home during coil operation.  I recently built my first coil.  I 
found lots of great info on Gary Lau's web site 
(http://www.laushaus.com/tesla/).  Also, here is a link to my 4" 
coil's schematic 
(http://www.halice.com/physics/4coil/4insch.gif).  It shows my 
control panel grounded to the house wiring BUT the power tranformers 
and coil assembly are ground to the RF ground ONLY.  This set up 
helps isolate your coil.

Cordially,
Hal in Tucson
