[QUOTE="westom, post: 1600527, member: 138367"] For over 100 years, protection from direct hits has been routine. But never with that considered power strip or UPS. Those only claim to protect from a type of surge already made irrelevant by protection inside your electronics. A completely different (and much less expensive) solution is required to avert damage from lightning and other equivalent transients. How robust is that protection inside appliances? This 120 volt sine wave UPS outputs 200volt square waves with spikes up to 270 volts. Perfectly good power for electronics due to internal proetction. But potentially harmful to motorized appliances. So what would that UPS protect? How many joules? Well a destructive surge can be hundreds of thousands of joules. So you choose a thousand joule protector over one with hundreds of joules? Yes, others say that is good because they ignored the relevant numbers. Hundreds of thousands of joules. They are both near zero protection. Again, a completely different device (unfortunately also called a surge protector) is for surges that are potentially destructive. Both UPS and strip protector are also protected by it. UPS is temporary power during a blackout to protect unsaved data (not hardware protection). Best power strip has that all so important 15 amp breaker and has no protector parts. Ttherefore is not a fire risk. [/QUOTE]
