Hard-wired surge supressor

I am wanting to add a hard-wired surge suppressor to my 2020 Hurricane 33X. Has anyone on here done so? If so, where did you put it? Under the bed looks to be the best option, just looking for alternatives.

The surge protector is the first thing that the power cord hits: once it at the coacxh. Mine is in an exterior bay...

My problem is that the power cable goes directly in behind closets to the space under the bed. I cannot find a way to re-route the cable to enable me to put it in a bay.

I'm guessing that you have an exterior outlet that your power cord attaches to...
Why not just plug into an EMS out at the pedestal?

The last external one I had got water inside during a rain storm and was inoperative, plus they are easily stolen. Hard wired ones are more secure and protected from the weather. I use an external one in the storage room for the RV, but I already have one to wire in for when I'm on the road.

I use an external at the post. I use a cable and lock to secure it to the post and my 30 amp cable connector. Someone would have to cut the cable or cut the two cable connectors to take it. Hopefully that will never happen.

Cable mine to the post. Would be really hard to steal.

Since no one is answering the hard wired question, can I pile on some more?

I am doing something similar right now; so I have few questions.

1. Where is the ATS Switch? Can you get access to it?
2. I bought a 4 ft shore cord that was specifically made to hardwire what would normally be the female end into ATS.
3. Which brand of SurgeGuard EMS do you intend to buy?
4. The newest portable Southwire SurgeGuard EMS gives you more features and protection than their current hardwired ones. Plus they have wireless bluetooth to put display inside RV
5. #4 is relevant because I can effectively plug my portable 34951 in an area within 4 ft of ATS or not. If I do; in my case it is inside the electrical bay and locked, if not; I can plug direct to pedestal.
6. The portable 34961 is Weather Proof, as long as it is plugged into Pedestal and upright, they guarantee it will not get damage due to weather. But if plugged inside it is effectively a hardwired unit that is secure and easy to replace or exchange with no future wiring.

I just bought a hardwired EMS that will go in the electrical compartment between my autoformer and my transfer switch.

That was my thought, I couldn't get to the cable anywhere else. Thanks.

I know there are naysayers out there, but I would install it in the AC breaker box, namely the (in your case) 50 amp main breaker. The breaker lugs typically have enough room to accommodate the extra wire and the neutral and ground bars are right there. Just ensure all the strands get into the lug and it is torqued to the proper spec. and then re-torqued it every 6 months to be safe as should be done anyways.
The speed that the surge travels, it does not matter if the protector is at the pedestal or a specific piece of equipment, the voltage surge will travel on the conductor until it finds a weak insulation point. That is, unless you have the proper surge protection to sacrifice itself instead of that expensive TV.
Being on the main breaker also protects you when running a generator or on the shore cable.

I installed my hardwired Progressive Industries EMS 30 between the ATS and the breaker panel.
That way it also protects possible voltage fluctuations from the generator.

I too was recently debating the pros/cons of portable post install vs. hard wire instaleld. I decided to just keep its imple with the portable power watchdog EPO. The main reason was that i want to protect my RV power cables, so installing the EPO upstream of the power cable serves that purpose. I also figured it was easier to observe if it was open/visible vs. being installed in some compartment. The one i got does bluetooth monitoring which is a really nice feature and the app works well. You can even see how much power you are drawing.

I put mine under my bench seat where the convertor is. 28A. Built a platform for it and I also have an invertor under there. That was the easiest place to intercept the 30 amp wiring and there was plenty of room. One suggestion if you do put it inside. is buy a smoke detector and put it under there as well. I had the wiring burn on one of mine. I think the constant vibration of driving caused one wire to work loose, creating resistance.

Thumbs up Hard wired surge suppressor .......

I installed mine under the bed were the shore cord comes in under there. Works as it is supposed to.
I have a 2013 Palazzo.

Good luck.

electrical bay

So I tried to cover all possibilities. I did not want to be stranded without the possibility of using electrical power in case I needed to replace my protector.

Further, I wanted an actual EMS, not just a surge protector.
https://www.progressiveindustries.net/ems-pt50x

I installed a Progressive Industries EMS-PT50X. It protects against all voltage fluctuations, not just voltage spikes.

Now. if you check out the link, you will see that it is a portable version.

wait a minute, you told us you "installed" this. how can that be?

In the electrical bay, there is a 50 AMP "socket" for my shore power cord. The socket is wired directly into my transfer switch.

I took the wiring from the socket, and put a 50AMP plug on it. Then I wired a 50 amp socket to the transfer switch.

last I connected the Progressive EMS/Surge in between.

This gives me the best possible EMS & Surge protection, but if it ever failed, I could simply remove it, and plug the socket & transfer switch back togethor.

Hope this all makes sense.

cheers!

The is a picture of the Progressive EMS under the bed. It is tight under there with the Xandrex Freedom Xi inverter, PPS power center, Progressive EMS and PPS ATS. I clean up the wiring this winter if it ever cools off.
