50 Amp Surge Protector - Does it work on 30 amp Pedestal

Hello,

my first post.

My wife and I have just purchased a Keystone Cougar 25RES 5th wheel. It has 50 Amp service.

I have two questions.

1) Can I use a 50 amp surge protector when I use a 30 amp dog bone connector to a 30amp only pedestal?

2) I am looking at a progressive 50amp portable SSP-50xl and progressive has a chart that doesn't recommend that for a 5th wheel in a chart they have. (see little red and blue dots) I like the easy and flexibility. And also that I have some protection plugging into the pedestal, with the portable version, not to mention cost is less.

Please see chart: http://www.progressiveindustries.net/portable-hardwired-comparisons

Any help from those that have learned appreciated. :)

Thanks

Tom

Yes! Get a 50A PI EMS.

With 50A, I think the line protection capabilities (lo/hi V and floating neutral) are even more useful than surge protection.
Well worth the few extra bucks IMO.

Really have no idea what that is? Hardwired version?

Of course you can as you're going to have to dogbone your 50 amp cable for 30 amp service anyway. However, you don't want just a surge protector such as the one you've mentioned, you want a full featured EMS w/surge protection, in this case an EMS-PT50X if you want a portable unit.

1. Yes, no problems at all.

2. The SSP-50xl is not an EMS, just a surge protector. I personally would not recommend it for most any RV. The EMS-PT50X would be a reasonable portable option. Yes, it costs more, but it protects against over and under voltage, which are the more likely problems.
