I have an older house that does not have grounded outlets. Previously, I have used 2-prong to 3-prong adapters to plug in my equipment (which remove the grounding ability). I understand that this can be dangerous, and surge suppressors will not function for large surges.
I have checked to see if the outlet plate screw is grounded (it is not) as well as searching for a grounding cable already installed (none there). This is a truly ungrounded outlet.
I would like to have a method of protecting my equipment that does not require a ground. For example, a surge suppressor that does not shunt excess voltage to ground, and instead turns off the circuit entirely in the event of a surge (using a fuse or a breaker, I assume) would be optimal. Do these exist, or is there a better option?
Please note that I do not feel comfortable running ground wire, and I do not have the funds to hire an electrician to rewire my house.
Also note that a GFCI will not be acceptable. I need an equipment ground, or something that protects equipment on 2 prong outlets.
EDIT: I did some searching and I found this. Would the "built-in circuit breaker" protect against surges and the like?
