I have a 2005-vintage RV-220-50 with no other surge-suppressor device. How many joules do I have (if any)?
Also, the orange light on my unit is flickering when plugged in and the source current voltage checks out okay. This has occurred on a couple of sources and far as I can tell, my unit is working. Does this happen?
