Autoformer/Surge Suppressor
In the market for a surge suppressor and find that the Hughes RV2130 Autoformer says it's also a surge suppressor . Does this mean there is no need to have both? Thanks,Mike

It is my understanding that the Hughes autoformer ( at least the one I have ) has basic surge protection. But it essentially a one time deal, after that, back to the factory for work. I called them regarding the sequence of setup for the autoformer and my Progressive surge/voltage protection device. They recommended putting the autoformer in first so that it has the opportunity to raise the voltage if needed, but that left it exposed to spikes. I ended up getting a cheap spike protector in front of the autoformer, which then feeds into the progressive unit.
