Hi guys. I'm in search for a sub-panel box that has fault protection built in. I know I've seen them somewhere, just can't think of where. I'm at a friends house now going over plans to build him a dedicated computer room (very multiple computers), and we thought that would be a nice feature. We are hiring an electrical contractor to do the wiring, but to save some money we are running all this stuff. As always, any help you can provide would be appreciated.
