EMS HW 50C Install

[ac7880]

I did the install on the incoming shore power cable just prior to the
first transfer switch, in the outside compartment where my invertor
and transfer switches are located. I am only wired for shore power
on the EMS50C, not generator nor invertor. I installed this way due
to space and ease of install.

I have only tested on a step down to 110 volt 15 amp connection, not
30 Amp nor 50 Amp. I'll test that the 2nd week of April when I move
the coach.

As wired and on 15 amp connection, the surge protector does make the
noise you describe. It is virtually identical to the noise each of
the transfer switches make.

On very quiet nights when on electrical hookups, I occasionaly heard
the transfer switches "hum" in the past from inside the coach (the
power compartment is below the bedroom floor). We run a seperate
smart charger "truecharge 40" that is silent except when the cooling
fan cycles on, and we can hear that fan inside the coach also. We
normally have the invertor turned off (it also hums when energized).

I would not want the surge supressor inside the bedroom without a
sound deadening blanket or pad between the unit and the bed. Did you
install it in a cabinet in the bedroom? If so, do you have space for
a sound deadening pad in the cabinet the unit is installed in?
