Autoformer / Surge Protection Order
I know there is a old thread on the Class 'A' forum, but I wanted to start one here for the visibility of us 30 AMP folks.
I have a 30 Amp Hughes Autoformer. I do *not* have a automatic transfer switch. I used the install kit that you can buy separately so that I have this:
Coach -> 5' Autoformer Cord from install kit -> Autoformer -> Original Coach power cord (with plug from the Autoformer install kit attached to the formerly naked end) -> pedestal. Just as Hughes recommends.
What I WANT to do is assure that a surge doesn't fry the Autoformer and the Coach. The Autoformer has some nice voltage regulation but its surge rating is not particularly good. Plus for the cost of it, I don't want the Autoformer performing surge duty anyway.
My thoughts were to put a SurgeGuard 34730 30 Amp in between the Pedestal and Autoformer. So essentially I'd have this:
Coach -> 5' Autoformer Cord from install kit -> Autoformer -> SurgeGuard 34730 -> Original Coach power cord (with plug from the Autoformer install kit attached to the formerly naked end) -> pedestal.
This gives me a few things:
A. Both Autoformer and Surgeguard can sit in the electrical compartment away from the elements and hopefully thieves
B. I protect everything I care about in the Coach including the Autoformer
C. The SurgeGuard cuts power between 102v and 132v. Why would I want the power cut if I have a Autoformer? The Hughes Autoformer is only going to bump my volts by 10% max. If my park volt levels are that low to begin with, at 103 volts my Hughes is only going to get me up to a little over 113 volts anyway. Super low voltage is not going to be addressed by my Autoformer, so I might as well have the system cut off until it can be managed again.
So - am I missing something here?
