Thanks to all that replied on and off list . A Friend that lives close
called telling me, he has a new RC-2800-P controller that I could use
to do my testing ..

## Which version of the M2 controller, do you have ? The latest version
is called a RC2800PXAZ..and uses a switching supply...good from
88-264 vac.
## Does your controller have a MOV on the 120 vac input ? Mine doesnt,
thats most of your problem right there. The 130 vac rated mov can installed
inside
the controller, between hot 120 leg...and chassis. For the price of the
controller box,
you would have thought they woulda spent the extra 1 dollar, to install a HD
MOV
across the incoming 120 vac.
## Ideally, you want MOVS right at the main 200A entrance panel. Typ they
will use
a 2 pole breaker installed into a spare slot in main panel.... then cabled
over to commercial
MOV box. MOV box will consist of 2 x 130 Vac MOVS, one from each hot
leg..to neutral.
## Then, everything in the home is protected. Otherwise, you could easily
get a repeat performance.
make sure the GH box has a MOV across the incoming 120 vac line too.
