Great question, Dirk!

Both the 30A and the 50A Hughes Autoformers have built in surge protectors so you won't need to have a separate surge protector installed. If the Autoformers does have to deal with a surge situation we have a replacement piece so you can get the surge protection back without having to replace the entire unit:

- 30A # HU86FR
- 50A # HU26FR

Attached is a video showing how to replace the surge protector for your reference.
