Re: [TCML] line feed/generator feed neutral/grnd ?
Hi Scot,
I'm not sure that I can adequately answer your question but one
thing that I have noticed is that the green or bare wire ground and
the neutral in all utility electrical hookups terminate to one and the
same ground buss bar in the fuse/breaker box and finally to the
ground rod at the electric meter. I still don't think I quite understand
all that I know about this ;^) Even 240 volt circuits to dryer and range
outlets now have 4 wires instead of 3 to incorporate a seperate
ground AND a neutral, which both hook up to the same identical
ground buss bar in the breaker box. :^/ So looking at it from this
angle, I don't see what the problem would be with running your
set-up as you propose without isolating it. Of course, you may
still need to seperate your generator from your line feed to keep
out the ground riding kickbacks from the coil if you're running
your coil with the generator, though. It seems to be accepted
as gospel truth to keep the dedicated RF ground seperated
from the mains line feed ground for this reason. I have personally
found this necessary with my Green Monster coil to keep the
metal surfaces of my control panel from giving me nasty little
RF burn shocks. However, Ed Wingate does not seperate his
magnifier's RF ground from his line feed mains ground but he does
not seem to have the RF potential on the metal surfaces of his con-
trol panel that gives those nasty little RF burn shocks. Not too sure
why he dosen't seem to have this problem with his setup, but I wit-
nessed it for myself by deliberately touching the metal surface of
Ed's control panel while he was firng his maggie at his Teslathon
this past weekend. No shocks/burns whatsoever.

Hey all...
got 2 questions... probably not truly coil related but I know someone
here has the answer!
I have an opportunity to run a coil on generator power and have a
question about the pre-existing hookup of generator to house wiring.
As is, the line voltage ( 240 single phase) can be cut out by pulling a
"disconnect" ( basically a unfused connector) from box #1 and it is
placed into box #2 ( basically it disconnects line voltage from load
(both hots line voltage) and reconnects both hots from generator to
load. Here is the problem... the neutral from generator is connected
to the "line supply" neutral AND the generators ground is connected to
the ground of the "line supply".
Do I need to have the system totally independent from line supply (
both hots and neutral/ground) or will the neutral connection as is
cause a problem??
Will the common connect points of the generator neutral and ground cause
any "feedback" into the line supply??
hope my description was clear enuf ;)
