For his and hers TVs with satellite boxes, dvd, AVR, etc., both surge protectors are rated at 3000+ Jules. Two lab tops on the same surge protector is 1500 Jules. We have several power failures in our neighborhood over the past 15 years, including transformers being replaced, and none of the devices have ever been destroyed. The circuit lights on the surge protectors are still green.
I do have to go along with having Tripp Lite surge protection.
