will this item work with adapters on a 30 amp rv or will it shut off both poles if it gets nothing from one?

I have a 2003 Monaco Diplomat with a build in EMS system which allows the coach to be run on 50 amp, and with an adapter, on both 30 or 20 amp. I have confirmed that the EMSHW50C operates perfectly fine on 50 and 30 amp. I have not yet tested it on 20 amp, but I suspect that It will work just fine.

Your unit appears to be wired for 30 amp MAX service, correct? That being true, you should never use any device allowing more than 30 amps to pass through it. The wiring in your unit will break down and the result will be fire. Hope this gives you a better understanding of surge protectors and circuit breakers.

If it see any trouble it will kill all power. Love mine! I'm sure it has saved me money from bad power.

If you have a 30 amp rv, why pay almost $100 more for a 50 amp surge protector? Get the 30 amp to match the power requirements of your unit.

It still works on 30 Amps. It even works when plugged in to 20 Amp at home to keep the batteries charged/maintained.

You could certainly add a wire to run the one pole thru both sides of the PI unit. That would definitely work since it would be just like using a 50-amp RV on an adapter to 30-amp service.

I fear that the other responders didn't understand that you have a 30-amp RV. In my opinion it will NOT work. You would have to buy the 30-amp unit. Progressive Industries great customer service at 919-462-8280 would give you the best answer.

Yes, as long as you have the adapter plug for 50 amp to 30 amp it works. I have used it several times when I could only get 30 amp service at campsite.

yes--the power is shared to the two hots (so in theory your single 30 amp hot line is being shared between your two 50 amp lines) and neutral is to neutral and ground to ground. The big thing to remember is that on a 50 amp rv line/plug it is really a double throw 50 amp breaker and line which means you are getting 100 amps at 110-120 volt to run all your stuff. When you use this plug you are limiting your power input to a total of 30 amps. You will not trip your breakers but if you turn on too many things you will definately be tripping the pedestal breaker. You are reducing the power input (amperage wise to 30 from 100 which is 1/3 of what you are used to under the normal 50 amp plug up). yes--the power is shared to the two hots (so in theory your single 30 amp hot line is being shared between your two 50 amp lines) and neutral is to neutral and ground to ground.

No, it absolutely will not. This is made to take two circuits (each 120 volt) and deliver two 120 volt feeds to the two phases of a 50A motorhome. The 50 amp motorhome will not know the limits of what it can draw on each phase (15A, 20A, 30A; or any combination of these limits); but it will have two feeds from two circuit breakers. A 20A and a 30A will provide the 50A motorhome a usable total of 50 amps. But a 30Amp camper is a single phase system; one inbound circuit feed is the limit. btw, a 240v device (very rare) in a motorhome will only work if the two circuits are from different phases; but all the 120v devices will work fine.

I use it with my generator, it kept blowing my GFI breaker, I put a regular 110 outlet in and it runs my trailer with both AC, I have used it at a few parks without a GFI breaker outlet, so if you have. GFI breaker in the circuit you need to replace it with a regular 110v outlet and it should work just fine. Hope this helps??

In a portion of my design (trailer wiring system), I have a 400 Watt DC to AC converter which connects to a AC wall outlet in my trailer. I have a trickle charger hooked up, so not many watts drawn. This has worked for me so far. The main wires going through relay end up having AC power through them. The actuator in the relay is controlled by magnet (and I still use 12 volt to control relay), so the magnet portion of relay doesn't make direct contact with AC power. Can't say for sure on 24 volt if it will work, since I still use 12 volts to actuate magnet in relay. I actually disected a relay to see how it worked before building my system. I hope this helps.

My best guess would beb that the 50amp version would not work for 30amp application. However, my 50amp works great have you considered the 30amp version for your RV? It should work just as great for you if you have a true 30 amp RV. I Have never tested the adapter with a 30 to fifty plug. We are parked where I could test That I have never tried it because of the built in set up delay start protector I don't think it will turn on. Would you like me to test it with a 30to50plug adapter on the 30amp circuit plug?

Not quite sure exactly what your asking but each pole carries 120v.. The whole contactor will not make a connection when the 110v coil receives no power so its technically normally open. When the coil is energized each pole is then contacted and current can flow in the circuit.Think of it as a 2 lane road and a draw bridge with 2 lanes. Each lane carries voltage independently of the other, but when the bridge is up neither lane gets to the other side. When the bridge drops both lanes can continue to flow.

This item plugs directly into a 110vac recepticul so I would have to say no. But if your just monitoring line fluctuations and polarity in RV parks this is for you.

you definitely have to turn off ac power. the 2nd clamp can go to the bare (earth ground) wire

Gene, I'm using one on an RV electric step that I put on my pickup for my wife's use and it has been good for a year, that's on a 12 volt system, then I have one on a 120 volt system and use it on my pantry door light. IT is on a thirty amp breaker. Hope that answers it for you...Z

I haven't used an adapter so I'm not sure what kind you are talking about. It does have an on/off switch. It has worked well btw. One day cure.

The total current drain for the three(3) cords may exceed the maximum rating of the 3-prong outlet. If this is the case , I suggest you use the RV Plug since an RV to Standard Outlet Adapter is relatively inexpensive compared to the Twist -Lock Connector that would be needed.Good luck and God Bless America !!!wysansi2008

I bought mine to use with a dogbone adapter to plug into my 50 amp cord. I can't say if the female end of this cable will plug into the inlet on the RV. If you Google the part number, you should find several pictures and might be able to see the female end better. I also believe that you can call any RV store and ask for the parts department. They should be able to answer this.

Yes, but only half your camper would be powered. Campers with 50amp plus is really 2 times 25amps with half the stuff connected to each. If you have 2 airs one will work. I have the plug above - only been able to use it a few rare times. Most parks that have a 30 and 15/20 the standard 15 has gfi - ground fault - that makes this plug useless. In places where you find 2 30's with in range - with an adaptor - this plug very useful.

I did not need one it should work without an adapter. If you haven't already purchased the unit I would advice against it, it's a piece of crap with no support when it fails and it will fail.
