Jumper wiring Leviton 6284 / X10 PZZ01 Whole House Block

["AlanTinNYC" <AlanTinNYC@xxxxxxx>]

Hiya.  I wrote to this group around Thanksgiving with a bunch of
questions about filtering out PLC Noise coming into my Manhattan
apartment from elsewhere in the building.  Then I had to drop off for a
while due to illness and some day-job issues needing greater attention.
 (See
http://groups.google.com/group/comp.home.automation/browse_thread/thread/43ab47ef51b37df8/b24ad73dc0d86d0f
if you really want to review the gory story.)

We're not quite done but have our issues about 98% resolved using a
number of solutions, and I will follow up on that thread at a later
date.  But I just need to check on something before I do any damage:

I now have a Leviton 6284 Whole House block working along with a
Leviton 6285 Signal Attenuator to really bring down the noise level,
and a Leviton HCA02 booster to bring the cleaned, attenuated signal
back up.  The 6284 seems to be functioning better than the PZZ01 we
tried in November, but I don't know if the 6284 is designed better or
if I just had two bum PZZ01s to start with.

1)  IS THERE ANY DIFFERENCE AT ALL BETWEEN X-10 PRO'S PZZ01
    AND LEVITON'S 6284?  Has any lab benchmarked their
    performance?  Are they identical?

2)  The installation instructions are nearly identical
    *except* that the PZZ01 instructions state "A jumper on
    the PZZ01 is needed from L3 to L2 when installing into a
    split-phase panel" and there is no corresponding
    instruction from Leviton.  I asked Leviton about this
    and they didn't know what I was referring to (or played
    dumb about a competitor's product).  I did find, though,
    that the 6284 performs better in my single split-phase
    panel with L2 jumped to L3 than without the jumper.  The
    ERROR light on the HCA02 still blinks, but the activity
    on both my ELK ESM1 and TesterLinc meters dies down
    dramatically.

3)  But on a hunch, I tried jumping L1 to L3 instead of L2
    to L3, and now I get no error indications for the first
    time in 9 months!  Assuming this had something to do
    with the noise level coming in on the phase wired to L1
    on the 6284's terminal block, I switched terminals so
    that the phase jumped to the L3 terminal now was wired
    to the L2 terminal (i.e., all according to the PZZ01
    instructions), but my error indicators came back.

In a nutshell, the 6284 sitting in my breaker panel performs best when
L1 is jumped to L3.  But jumping L1 to L3 is NOT DOCUMENTED in the
PZZ01 literature, and jumping terminals on the 6284 is not documented
by Leviton AT ALL.

For safety's sake, I have the whole house block switched off until I
find out more.  My wife loves our new home and I am not about to burn
it down.  But can anyone confirm if it is safe to jump L1 to L3 on a
Leviton 6284?

Thanks, all!
