I would however go with the Surge Protection first and get and install the AutoFormer behind it. The AutoFormers surge protection is sacrificial and requires it to be shipped back to Hughes for repair it is also more expensive so I prefer the SurgeGuard to take the first hit. </div></BLOCKQUOTE>
We went with the Progressive surge protector first for the same reason. Another reason is that, although the autoformer also provides some degree of protection against electrical surges, the surge protector (particularly the ones from Progressive Industries) provides a higher degree of protection.
The ideal setup would be to have both a surge guard AND an autoformer. But budget dictated only one and we went with a Progressive Industries surge protector.
There is an interesting discussion going on elsewhere in this forum called LIGHTNING STRIKE
which is relevant to surge guards.
