Just get rid of the surge protector. You don't need that if the Surge Protection Circuit Breaker you have in the electrical chain is better than the Belkin/Huntkey. I am not an expert but I'd guess that the chances of a surge getting through an industrial strength surge protector and the servo are rather low. Vertex would be a good source of advice based on their assessment of your current Surge Protection Circuit Breaker.
Instead of using a power strip like Belkin/Huntkey, especially if you already have surge protection and servo in the electrical chain, just get a box with switches and sockets already set in the box from your local electrical store/online, open it up, check the thickness of the wire used inside and if it is of poor quality/thickness then just buy a good quality length of 5A power cord from a store and redo the internal wiring. Take and mark out pictures of the internal wiring of the box before you start in case you need a reference. It's not too difficult to replace the wiring if you are reasonably handy with a screw driver and wire-stripper.
Hmmm, Thanks for the Tip.
