Re: [TCML] forgot the safety gap on the srsg

Nice - that'll do nicely!

You mentioned that you have a Terry filter.  It sounds like you need to set
the safety gaps.

Also, a Terry filter has MOV's which also perform the same function as a
safety gap.  If you were operating without a safety gap and the RSG failed
to fire (resulting in a too-high voltage condition), the MOV's would
conduct.  If that condition persisted, the MOV's would get hot and
ultimately fail, shorted.

I agree with Phil's comment that the blower is unnecessary.  The airflow
inherent in an RSG is all that's needed, unless the motor itself gets too
hot.
