[QUOTE="westom, post: 1439942, member: 138367"] View the numbers. That near zero protection is sufficient to claim 100% protection ... subjectively. View the fine print. So many exemptions. They need not honor your claim. Why would they? A protector too close to electronics and too far from earth ground cannot do protection. Sometimes even makes damage easier to any nearby appliance. A protector adjacent to electronics must somehow block or absorb a surge Open one up. Obviously it cannot. Obviously a surge is connected directly to nearby appliances as the OP demonstrates. Better protection is already inside appliances. In his case, a surge was so large as to even overwhelm that protection. Protection is never defined by a protector. Not even a 'whole house' protector. Protection is defined by what absorbs hundreds of thousands of joules. 'Whole house' protector is superior because it makes that low impedance (ie 'less than 10 foot') connection to earth. Then superior protection inside each appliance is not overwhelmed. How to make a 'whole house' protector even better? Upgrade what does the protection - earthing. Protection is always about a surge absorbed harmlessly outside the building; in earth. [/QUOTE]
