EMS 50C - Leroy Eckert - 03-26-2007 03:28

I guess everyone can make their own decisions based on the data at hand. I'll
keep the portable since I have had excellent results using it and I will not
have to be concerned with the buzzing noise others complain about or the
potential of compromising factory wiring. If a power surge takes it out, I'll
pull it out of the pedestal, and repair it or replace it. The less maintenance I
have to perform inside the bus, the better I personally like it.
Thanks as always for the input. It is good to read everyone's opinion and
conclusions gleaned from the same data.

As you said Leroy "With all due respect" then "however", I have had the
generator fail me and take out a new tv. Ernie had his plug fail and took out a
bunch of stuff for him just awhile back. In my case it ain't broke now and I
don't want it to become broke. Been there, done that.

Good luck.

With all due respect, your input may be absolutely true.

However, I purchased my Surge Protector (that is how it was sold) for one
reason only. To protect against irregular park power, nothing more, nothing
less. . I would not expect it to inspect my power cord for defects or tell me
when my transfer switch is taking a &^%$. I do that. Of course, I cannot see the
connections at the transfer switch.

If I want to start my genset, and I do so twice monthly when plugged into
shore power, I turn off the pedestal breaker and pull the plug. I do not need to
know anything about frequency or depend on an instrument to do it for me. That
is all I am saying. I have been using the Portable for 2 years(about) and
everything is fine.

I know I am off the chart on some things, but it it ain't broke don't fix it.
I have had very good luck with it and until something changes, neither am I.

Frequency to me means how many times I get to walk from the pad to the cooler
for another Lite. LOL

Leroy,
The 136 second delay is to protect air conditioners that don't
have a built in delay. That way if there is a short power loss or if
the unit shuts down it will allow the AC to bleed the presure down
before starting the compressor. In the permanent surge protector
unit it is adjustable to a shorter setting if your AC units don't
require it.

EMS 50C - Gregory OConnor - 03-26-2007 04:35

Leroy, The majorsell for me on a portable unit is 1- stopping the
slectrical powersurge outside of the coach 2- protecting the 50 amp
BB powerchord from passing and being compramised by a surge or
overmax draw 3-allowing visiting guests to use protected power at my
home after I move my bus from its perch. Hard wire protection
(vesectamony) may be the best because you never worry about hooking
up the protection. Hardwire is trick and typical of Bluebird
convienence. Hard wire provides twice the protection (gen/shore).

The passion within this thread is driven by the comforting egarness
of forum members wish to help members.For now I dont use SPotection,.

EMS 50C - Richard Hayden - 03-26-2007 07:48

Ralph,
I'm the one who reported the death of the tv from a generator problem. That was
on our previous '81FC. I have also experienced a generator output problem on
our current '87PT. Our genset on this bus is a 8kw Power Tech and the "brain
board" suddenly quit causing very high voltages. On our previous bus the
generator was the standard Kohler 12.5kw. As on all arrangements on BB's, it
had its own breaker box close to the unit. You are correct, these thing must be
maintained. What happened on the '81 was the screws in the breaker box worked
loose over time to the point that they were not making continuous contact.
Hence the spikes and the demise of the tv. When the brain box failed on the
'87, I turned it off as soon as I noticed the voltage was very high and was very
lucky that apparently there were no appliances on line at the time since nothing
quit working. Obviously, my reaction time can't match that of any protective
device so I was just lucky.

But, you are correct, it is a matter of choice and that is why both
configurations are available.

Respectfully,

Dick Hayden - '87 PT 38 - Lake Stevens, WA

Hello Bill and All:

My thoughts on the EMS did not and does not pit one system against another
of the same ilk. Both have value albeit of different inputs and of course
lifestyles and present equipment.

With the unfortunate experience Ernie braved on his power cable, we have
all learned a very valuable lesson, and that is preventative maintenance. I
agree, that I missed the most obvious of things time> that the portable unit does not check the power cord or gen set
incoming power. So I will attempt to separate my thoughts on each matter.
These units are good, no doubt but not a wiz bang cure all and the interior
parts are subject to the same amperage overloads as any other system.
Amperage translates into heat and heat translates to predicted mean time
failure for relays, contacts and electronic parts. We all know that relay
contacts, over time will discolor with heat aka amperage, then progress
from there to pitting of the contact surface thus an actual welding of
those very contacts that protects down stream systems by opening and thus
stopping the damaging amperage (spike). Ok, I doubt there is a study on the
mean time fail rate or percentage of that type of failure.

While true, the portable will only do a partial job, but is not the main
theme here and of these units to disconnect when a power spike or surge
comes from the errant power source in an RV park?

Until one of the members reported that his gen set caused the death of a TV
set, I had not, in 10 years, seen this happen. Some things I tend to take
for granted, such as clean power from gen sets because, unlike RV parks, it
is a steady known source of power for our coaches. I tend to stay with the
thought, "I have to trust some things, and the gen set is one of
those." And also tend to go with the percentage of failure and the gen
sets are on the VERY low end of the fail scale. We have learned, on this
Forum, over the years, that proper maintenance of the gen set is mandatory
to maintain a steady known source of power and I see no reason to have to
protect from that source. That is my opinion only and perhaps flawed, but
perceived to be a truism.

We are also talking about 2 major types of input switching in these coaches
as well. That is the manual transfer switch and the automatic transfer
switch (ATS) The first, manual, is owner controlled as to the power being
allowed into his coach. The latter (ATS) is not owner controlled. Having
separated those two, My thoughts go to the two types of EMS units. One the
portable and the other the hard wired. The portable, for the manual
transfer switch will work the job of the intended use, and that is checking
the incoming power in the RV park pedestal and can be checked prior to
switching the manual transfer switch to allow the power into the coach.
While on the other hand, those coaches with the (ATS) do not have that
luxury and I agree, the hard wired is the best choice for those coaches.
and offer a better protection. Save for the forgotten power cord, which is
not checked, I still belive that either or will get the main job done for
the manual coach.

Any system can be taken to the point of over kill. What I don't know about
this EMS unit, is will it shut down with an over amperage down stream as
well as incoming? If it does then, in staying with the original theme of
"protection" from errant RV park power, both units, each in it's particular
usage get's the job done. If not, then the EMS does have a fault that can
fail.

Bottom line, the EMS is a GOOD thing but not a cure all and life style and
choice becomes the deciding factor. It is hard to believe that MOV's and
POV's will burn and open as they are designed to do in under a millisecond.
And a millisecond is all that is needed for a huge power spike to take out
sensitive electronic systems even though protected. A huge spike of voltage
or amperage will actually bridge and air gap of 1/2 inch or less no matter
if a relay contact is open or closed, but then that is going off the deep
end of the far side of the scale. I have not seen a POV or MOV that reacts
in the nano second range as this unit advertises. (still old school here on
that)

Apologies for this being so long winded, it is just some thoughts on the
subject. It still comes down to what each owner is comfortable with and
works best for him or her.

> Ralph,
What little I know or understand about electricity will fit on the head of a
nano needle.
As I previous stated I think our greatest exposure to a possible bad power
situation is at the post in the parks. If the post checked ok why not plug the
cord to the post and then plug the cord to the PT 50 to check the cord. For
those who still have worries about the generator install a hard wired unit on
the generator output before it connects to any transfer switches. This set up
with the portable and hard wired unit would cost about $600.00 for the two
units. Do the portable now and the hard wired one to the generator next year.
Still some cheap insurance.
Question; What if you are in a park that only has 30 amp service. How would
this work then would you then need PT30 or will the PT50 read the 30 amp ok.

EMS 50C - Leroy Eckert - 03-26-2007 08:33

Yep, I agree with you, Gardner, Richard and Ralph. Ralph's old school analysis
is exactly how I think when it comes to the Genset (I rely on it) and the
Portable Surge Protector with one exception. ATS coach owners do have the
opportunity to check power before they plug in the cord. All you need to do is
read the codes. If it is showing E-0 all is well. Plug it in. In an effort to
prevent a dead TV, I use an additional surge strips on those and other
electronic devises, and as Ralph stated may not be a cure all.
Last Summer lightning got my 56" wide screen power supply at home which was
plugged into an independent constant voltage transformer and surge protector. 4
other unprotected TV's in the home were not damaged. Naturally, the really
expensive protected one took the hit. I think it got to it faster than a nano
second.
I know enough about electricity to know that I do not know enough also, but I'm
gaining on it.
Choices, choices, isn't this fun?

I honestly do not know if the EMS50 will work off a pig tail. I don't have
one, perhaps one of the guys will have an answer.

EMS 50C - Ralph L. Fullenwider - 03-26-2007 11:57

HI Dick:

Interesting, this is the sort of thing we need to hear about on the Forum.
Most VR's (voltage regulators) shut off when they fail.

In this case, then yes, the EMS hard wired would protect against the over
voltage. Still, so far as I know of it is a rare thing but may induce me to
change my thoughts on the gen set. It is food for thought. Thank you

From my understanding it should work all the way down to a 15 amp circuit, 120

> Ralph,

What little I know or understand about electricity will fit on the head of a
nano needle.

As I previous stated I think our greatest exposure to a possible bad power
situation is at the post in the parks. If the post checked ok why not plug the
cord to the post and then plug the cord to the PT 50 to check the cord. For
those who still have worries about the generator install a hard wired unit on
the generator output before it connects to any transfer switches. This set up
with the portable and hard wired unit would cost about $600.00 for the two
units. Do the portable now and the hard wired one to the generator next year.
Still some cheap insurance.

Question; What if you are in a park that only has 30 amp service. How would
this work then would you then need PT30 or will the PT50 read the 30 amp ok.

EMS 50C - one_dusty_hoot - 03-26-2007 12:49

One of the strongest and most common sources of
high voltage spikes is from inductive kickback when
voltage is removed from a motor or relay or coil or
an inductive load. External causes would include
lightening or large power equipment or loads changing.

Consider the automotive spark ignition, as points
open the coil field collapses presenting a hi voltage,
in thousands of volts jumping the spark plug gap.

This same principle hold true in our coach relay coils
as a switch or contacts open. Many times you can notice
a spark when this happens under the right conditions.
Automotive relays sometimes have a small diode in
parallel with the coil to shunt this high voltage.
Sometimes a small capacitor is placed across the switch
contacts to do the same thing much the same as the
condensor was placed across the ignition points to
prevent them from burning. Just look at all the
relays in a coach, my goodness.

If I use the manual transfer switch I like to do so
when connected to the least systems or components. The
same thing holds true for contacts there arching when
a load is switched or removed.

For the ATs it would not take the care that you or I
would removing the load before activation, it just
switches, when certain conditions are met. All the
more reason to have the EMS downstream of the ATS.

I don't believe it beneficial to have the EMS on the
generator side before th transfer switch either. Why
not mount between the transfer switch and the main
panel?
