Good to know, CAVIE, that an autoformer is TOTALLY different! Except you are wrong. Catch up!
Per Hughes at: https://hughesautoformers.com/product/30-amp-3600-watt-booster-with-surge/
“Introducing the World’s Only “All-in-One” RV Power Solution.
The legendary, original, and patented RV voltage booster, now with the world’s most advanced surge protection.
The all new Hughes Autoformer 30 amp power boosting autoformer (RV2130SP) has the same performance and reliability of the RV2130 but now has advanced surge protection built in! The unit offers 2,400 Joules of surge protection. As an added feature, the surge / spike protection module is also replaceable. In the event of a massive spike, the surge unit will take the hit ensuring your booster and more importantly, your RV is not damaged.”
No. Lwidds you have fallen for the ad-man's glib line.. The Hughes is an autoformer. boost only far as I know with MOV's to supress spikes and yes they can be replaced.
If you get a real surge (Like 2 second surge) the MOV's sound like firecrackers as they "Blow up" (not much of an explosion)
ANd they do nothing to protret you Plug a 30 amp rig intto a 240 volt outlet or a TT-30 wired for 240 They go BANG and you get fried.
Both the southwire and Progressive Industries units protect you
Open neutral. open ground. Power "Blink" they do nothing for you both PI and Southwire do,
The Hughes just corrects the voltage if its close enough and clips spikes.
