I don't get any shocks of any kind; also when
I had the Klimaire mini-split system installed
they checked the power panels and the outside
box because they had to tie into it. So wouldn't
they have noticed if it wasn't ground? Since
they tested the 220V with meters etc.

It's a single mobile home by the way, if that makes a
difference in code etc. and live in the desert
near Palm Springs on the other side of the mountain.

Also I had (4) different contractors come out
and give me estimates and they all saw the panels
and the outside box as well and no one said anything
about grounding.

Here's my current APC Surge Arrest; It doesn't have
a switch per se but a reset button that doesn't seem
to work because I've tried it. Maybe I need to hold it
in longer to activate it? Or because the problem is
constant it won't reset or whatever it's suppose to do?

But this is why you're buying another surge arrestor
right ? The current one damaged by the mis-applied
220V to the 110V surge arrestor ?

It's probably blown out inside. That would account
for the red LED reporting the functional failure.

Check for symptoms again (red LED) when the new
one you ordered shows up. The red LED should be off
on the new one, and the new one ready to function.
