Autoformer
What would be the proper sequence of using an Autoformer and a surge protector from coach to post?

The Hughs were crumbly toast but they are autotransformers. A surge protector is a strip or box that has receptacles on it. Gas tube discharge devices are discrete as are TVS suppressors. Theyare not expensive. I have a 50 dollar strip surge protector gift that I took apart and it has a lousy 4 MOVS inside. Oh yeah and a nickle sticker bragging about a fifty thousand dollar insurance guarantee.
In the early 2000's I spent several days in a Mazatlan RV Park that had a couple dozen rigs with their ACs cycling. The sine wave on my Tektronix looked likeca relief silhouette of the Rocky Mountains. Spikes to 550 volts.
MOVS react too slowly to be of much use. An isolation transformer works best but coupling TVS with gas tube discharge components worked about several dozen times better than straight MOVs. When anything hit 190 volts peak-to-peak it gets CLAMPED. An autoformer transformer by itself offers 0.000% TVS protection as one leg is NOT isolated.
A DC fed 3.0 Kw UPS of course would offer the ultimate transient and voltage protection.
