I was told by Hughes when I purchased my Autoformer to plug the Surge Protector in after the Autoformer like option #2 above.....
They told me the surge protector was no longer needed since the Hughes has one built in, but would use it if I already had it....
Two comments: 1: Thank you (that option 2 was my post)
2: The built in replacable surge protection is MOV (metal Oxcide Varisistors as best I can spell it out) and these are very good at clipping spikes (Short bursts of too much voltage)
This is ONE of the ways that my TRC Surge Guard or the PI HW-30/50 o PT-30/50 or the new PT-30/50 replacement protect you
Never hurts to have more MOV's (Up to a point and we are not even close yet)
But the Good Systems like the HW-30/50C or the portable (plug in) equivlent also protect you if you plug into a 240 volt outlet or if power goes out for like just one second (They hold off for between 2 and 3 minutes which is way easier on the A/C) and also. after a power fail. hold you off for 2-3 minutes when power comes back (It's kind of roller coaster ride during the first minute)
They also protect (By shuttng off) if power goes too low.
ANd check for bad connections as well.
IN short.. Like I said before. I use both.
