Install Progressive Industries EMS-LCHW50

Today I will install this EMS after transfer box for protection from both generator and rv park post AC power.  I want to keep both ATSs.

My question is this: what wire do I splice this EMS in to below the bed?  I have attached a picture to help you to describe where to splice in, including the schematic for the PD52

I installed the Precision Industries PD52 last year when the original ATS failed.  It works fine, a relay feature unit was not available locally that day it failed, the PD52 was, and is fine.

I also have ordered Hughes PWD50 with EPO (emergency power off) a pedestal 50 amp bluetooth model with power disconnect to protect the two ATS transfer boxes and check pedestal prior to plugging in.

My question is this: what wire do I splice this EMS in to below the bed?

On a '97 coach the top transfer switch should be for generator or shore power.  You should have a cable (I can see it in the pic) that is #6/3 w/ ground that goes directly to the back of the main breaker panel. That would be the one you want.

The bottom transfer switch is for inverter or circuit #5 (from your main breaker panel) that will be protected through what you install  in the cable listed above.

With this set up the only thing that won't have EMS protection is your appliances that are powered if your inverter goes haywire while you are using it for 120v A/C  power.

Thank you, Mike. Great, makes sense to me.  I appreciate your comment about the inverter protection.  I had not thought about that, hoping my Xantrex SW2012 is well engineered. 

Now off to the store for a pigtail to connect with 4 wire, 6 gauge.

With your coach being a 02 it could be laid out different than a '97.  If you have the same lay out as shown in the pics I would say yes it is the same.  I will see if I have a hard copy or if there is one here in the Wiki section of an A-2700 for your coach as it will have the for sure answer.

Mike

Edit:  The A-2700 print I have for an '02 shows your coach wiring is the same.  Now the 2 transfer switches can be side by side rather than stacked but will be wired the same.

My buddy noted that Foretravel and Bluebird were the only ones that used two transfer switches.

Not sure if I understand his comment when I asked him why he was using the Magnums transfer setup versus the factory second box I think me mentioned that the power share part of the inverter would not work if the inverter were bypassed?

We did install the auto former in the reel bay and if it gets fried some how I can bypass it in the bay.

Installed the progressive industries unit in the transfer box area.  Has a wires manual bypass switch and a scrolling readout.

My buddy complained about the stiff wires like many others here have before.

Installed its panel next to the 12 volt fuse box.  May replace that  box with a marine resettable flip breaker circuit panel instead someday. Had several customers 30 years ago have me change out their panels for the marine type.

Glad to see the like thinking of great minds. 

The blue sea M2  panel we installed where the inverter panel is does show the volts/amps/cycles on both legs on its always on(adjustable time off) OLED panel.

Has various alarms in its abilities.

Turns out getting both legs power in the hutch area was a bit more involved to connect the under the China cabinets 110 volt outlet to the gauge.  Had to route it through the bath cabinet?

The other 110 volt leg as already there for the powerwatch meter we removed.

.7 to 1.5 watt monitoring panel power consumption.

We installed the EMS on the cable between the transfer switch and main breaker on main breaker panel.

Removed the cable end from transfer switch, and attached the cable end to the output side of EMS.

Ran a new 50-amp Romex (#6 wires, black, red, white, green) to the same (now-empty) terminals on the transfer switch, other end to input of EMS.

This configuration will protect generator and shore power.

Buy a length of new 50-amp Romex that is longer than you think you need, as you want the ability to shove the EMS where every it needs to go. And you want extra for baring copper ends.

Thank you all, installed as all others recommended, after the ATS. Triple checked all connections, no need to cause a problem, such as a fire.  With the replacement costs for air conditioners, micro, waves,  residental refrigerator, tvs, toaster ovens, etc., let alone the time and peace of mind, I am totally glad I did this upgrade.

It was first brought to my attention two years ago by Barry and Cindy.  My wife's comment was why did we not do this two years ago, great question.

I waited because of what I thought was complexity and emerging tech such as the recent intros from Hughes.  I could not find anything better or with such reviews and recommendations from forum members.  For a portable unit I did order the Hughes Bluetooth with power cut off.

I just cut the wire going from the transfer switch to the breaker panel and inserted the progressive EMS in line.  Then I just placed the little display in the fuse panel...it can be pulled out if desired.

My guru buddy spaced out the 12volt panel and ran the wire out to the bed pedestals outside surface and put the display outside the bedframe.

I installed our Progressive EMS HW this morning and just want to extend a huge shout out to all who helped on this forum, especially Barry & Cindy! 
Went to Lowe's yesterday and picked up what they had available, unfortunately, it was not SOOW cable, but it was good for 55 amps #6 4 wire.  Got 4 feet and glad I did.  Cable is stiff and hard to work with in tight places, but hey, it worked.  Installed the EMS after the ATS (Auto Transfer Switch) so we are covered on both the shore power and the generator power.  Below are a few photos!

Help me understand why you would need 2 surge devices, one at ped and one built in? Why not just one?  Redundancy?

Since I don't have automatic transfer switches anymore in my coach, but a blue sea manual shore/gen switch, if I wanted to protect from both shore and gen, I would wire this after the switch, correct?
Watched one video where the guy flush mounted to remote. Looked pretty good. That would be the way to go IMO.

Bob,
The pole mounted is to protect the transfer switch you don't have. under the bed is to protect the coach from both gen. and pole. You having the manual switch would wire after the switch as you thought.

Well after looking at the setup again, that won't work. The feed from the transfer switch goes to the main AC panel. The inverter panel is fed via the inverter. So to cover both I would need 2 correct? Or just 1 to provide protection from shore power/generator.
Thanks craneman. I saw your post after I posted this.
Yes I guess putting it in the out put side of the manual switch would cover both.
I see it on Walmart online for a lot less than elsewhere.  246$
Want to protect those 2 new ac units...

You would need 2 to protect from the inverter also. Your system is different. I can't comment on dangers of an inverter causing surge problems and haven't read of it ever happening, but maybe a very low risk item.

Thats what I was thinking. Victron stuff is pretty reliable.

You might want to mount the protector on a shelf or similar so the face of it looks up.  I've been into the internals of mine a couple times, repaired some failed solder joints, adjusted trimpots. Just a suggestion...

Thanks for the reminder Mike.  Thought about it and they are all protected with the exception of the microwave.

I mounted mine, not on a shelf, however I did attach it to the back wall with the face mounted up.  I used a 4' section of new wire to come out of the ATS (automatic transfer switch) to the EMS.  The stiff wire held it up and against the back wall, and to the left of the ATS.  I then used heavy duty Velcro to attach EMS to back wall.
