Do surge protectors work without ground?
Grounding is a critical element required for proper surge protection. In regard to the question about whether surge protectors work on ungrounded outlets, the answer is no. Surge protection equipment typically uses components called metal oxide varistors (MOVs) to divert excess current into the ground line.
Where do you place a surge protector?
Often, they are located near the coax entry point, or near the transmitting equipment itself. The logic being that them keeps them as close to the reference ground point as possible, in order to provide the best path to ground when the MOVs clamp.
Should I use a surge protector for my TV?
Desktop computers, laptops, televisions, gaming systems, and charging phones should all be plugged into a surge protector, so they aren’t damaged in a storm.While it is beneficial for all electronics to have the protection of a surge protector, only items that have sensitive microprocessors need surge protectors.

Do surge protectors make noise?
Yes, surge protector makes noise. This is true for all electrical devices and components. However, surge protectors are not loud.

How big a surge protector do I need?
If you’re trying to protect things like cell phones, basic laptops, printers, routers, and copiers, you’ll want a surge protector with a rating between 1,000 and 2,000 joules. This rating is also large enough for your power tools and other building appliances.
