Except for the surge protection which operates in the on or of position.

thanks for all the replies- one more question.
will the PI EMSLCHW50 eliminate my need for the surge protectors in the coach for the TV's and laptops?

thanks!

I believe we are talking about two different things. On Progressives web site it talks about the remote display and a remote panel the same as in the manual. I have sent an email to Progressive, should have an answer tomorrow.

I would say YES, but a call to Progressive Industries would give you a more technical answer.

I do know that you are NOT suppose to daisy-chain the strip surge protectors.

Preferred location of the remote display probably varies--I like to see "what is what" when I first plug-in to the pedistal, so I have it mounted inside the utilities bay. If the power kicks off sometime after the initial plug-in, its usually low voltage in the park. My "el-cheapo" wall plug 120v meter from CW usually lets me know early on if low voltage is going to be a problem. Guess you can solve the issue of location with two remotes but Progressive Ind is pretty proud [$$$$] of this option.

Why is that?

Seriously, I would like to know why. Is it because it affects the surge protection or is it just an overload danger for the first strip in the chain from too many outlets being added?

Can I daisy chain surge protectors?

No. Surge protectors must be plugged directly into a grounded outlet to work properly. (Underwriters Laboratories prohibits daisy chaining) Never plug a surge protector into a plug strip or plug adapter.

Thanks for the response. That gave me enough info to find this :http://www.compliance.gov/forms-pubs...aisychains.pdf and other similar references. I've seen this issue come up before and the consensus was circuit overloading was the issue with daisy chaining, not inhibited surge protection, but I wanted to verify it. As long as there is a ground connection, the wiring is heavy enough, and the load doesn't exceed the circuit capacity, daisy chaining will not be dangerous and will not inhibit surge protection. However, it will be illegal.

In the case of the Progressive Industries surge protector, that is wired in ahead of the RVs main panel so the daisy chaining prohibition wouldn't apply here as long as multiple strips are not being daisy chained.

I don't think there is any question that campground power issues are much more common. After all, that's the prime purpose for this protection product and the main reason most of us installed one.

But you make it sound like it's an either/or proposition. It isn't. The question is whether you want protection ONLY from campground issues, or if you want protection from campground AND generator issues. Why not go for both? The common reason given is to protect the transfer switch, but transfer switches are relatively inexpensive, and are not easily damaged by the sort of wiring/power issues that the EMS protects.

Another reason for putting it AFTER the transfer switch: so you can use the display to monitor the power draw from the generator. (I like to know what's going on.)

When your plug-in volt meter reads zero, it won't tell you anything that you don't already know - there's no power. But an inside EMS display can tell you WHY you don't have power, and whether you can do anything about it. For example, in the middle of the night, the power went out. I looked at the inside display, and saw that the EMS cut the power because the voltage was out of range. That told me there isn't anything I can do about it right now (like resetting breakers) so I went back to bed, comfortable in the knowledge I was being protected. But if I didn't have the display, I would've had to get dressed and gone out in the rain before I realized there was nothing I could do at the time. This has actually happened to me a few times, for both high and low voltage.

Besides voltage and status, the current draw readout on the display is very helpful at times.

I wish I had more information on the EMS of my coach. The panel displays the service and I have a page that displays the L1, L2, Neutral and Ground conditions but I don't know if the system is built to not connect the service to the coach if it does not qualify.

Does the Progressive disconnect if a problem occurs or prevent connection if a problem is detected? Maybe both?

Winnebago should be able to tell you what the specs of your EMS are. The Progressive checks the condition of the incoming power before allowing power into the coach. Once power is established then it monitors the power for faults and will disconnect if a fault is detected. It will continue to monitor the power and if the fault is corrected it will then allow power in again. Seamless in operation.

Of course! I should have thought of that. They are usually great about answering questions like this. I might call later today if I get a chance. I'll post what I find out.

Thanks,

I finally got an answer from Progressive about my question if the remote display and the remote panel are the same thing. Yes they are, the manual and the web site have a type-o where it says remote panel. And yes as posted by others when remote display is switched off all safety features of the EMS are bypassed, except for the surge protection.
