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

But not entirely correctly. ;)
I owned a portable TRC 34370 Surge Guard (now replaced by the improved 34380) and time delay is fixed at 128" which cannot be changed. The hardwire version is also set at 128" and AFAIK cannot be changed either. I now have a Progressive Industries EMS-HW30C hardwire surge protector with delay that can be changed from 15" to 136" by removing a small jumper inside the unit. Since I would like the ability to run the 15" delay when not using A/C but quickly switch to the longer 136" delay when I am I removed the jumper and wired a SPST switch across the jumper contacts so now changing the delay is as simple as throwing the switch. Delay for the portable EMS-PT30C is fixed at 136" and cannot be changed. As far as A/C is concerned, some models do feature their own built in delay, some such as my Dometic Brisk II do not so I always run my EMS-HW30C with the longer delay when running A/C.
