I live in San Carlos. The entire building is ungrounded. I have investigated investing in grounding to the breaker box and installing grounding wires to all the outlets. But this ain't happenin'. The perimeter of the entire building is surrounded by rooves or cement slabs: (1) First, I'd have to find out the owner of an adjacent property, (2) Then get permission to break up cement to find ground. Good luck with this!
I'm assuming that surge protectors are 100% useless without grounding but is this correct? Are they partially useful?
So far a computer and a Samsung television have been damaged (latter) or destroyed (former). I'm building a next generation computer for about USD $1000. I'd sure like protection when the next voltage spike occurs (puntos de voltaje).
This is where the EE's come in! Is there any device, either a device for a particular piece of equipment, or any change that could be made in the breaker box to protect sensitive electronics from surges ???
