Chris - read only what is posted. Stop reading hidden meanings. Your biases are only confusing you. If you want to learn, start by assuming everything you know was probably wrong. Then read only what was posted - especially every number.
Zerosurge accurately shows what that indicator light reports. Nothing bashes MOVs. Exampled were MOV protectors so grossly undersized to maximize profits - to not provide protection. Nothing in the Zerosurge pictures discuss 'whole house' protectors. Did you get that? Zerosurge was critical of plug-in protectors that do not provide and do not claim to provide protection. Completely different is a 'whole house' protector.
Why assume plug-in and 'whole house' protectors do same? If you read only what I posted, you learned a 'whole house' protector does things that a plug-in protector cannot. A 'whole house' protector even earths direct lightning strikes and remains functional. A 'whole house' protector means nobody even knew a surge existed. And still some so ignore numbers as to believe MOVs are sacrificial devices.
Effective protectors are constructed using MOVs. So let's make it simpler. Point 1: Some of the crappiest protectors use MOVs. And some of the best protectors use MOVs. Zerosurge pictures show that IF you make no assumptions. Where does Zerosurge discuss 'whole house' protectors? It does not - obviously.
Let's make it simpler. Point 2: If you want to be scammed, buy a plug-in protector. If you want protection, earth a 'whole house' protector. A list of 'whole house' protectors were posted yesterday. Posted earlier were the numbers you memorized - because selection mean you grasped every number.
Let's make it simple. Point 3: Wall receptacle provides no earth ground. A receptacle is safety grounded; not earth grounded. Reading only what was posted means you read that earth ground "must meet and exceed post 1990 National Electrical code". Not safety ground. Every ground to wall receptacles obviously is not earth ground. If you disagree, then your post includes many numbers that say why you disagree.
Numbers Chris. Your every reply never has numbers. That suggests your eyes routinely glaze over with each number. You are learning nothing if reading subjectively. What was posted is consistent. But if you did not grasp every number as if your life depended on it, then you did not read what was posted. Ignoring numbers explains why you are confused and frustrated. Explains why your replies are inconsistent with what was posted.
Stop being accusatory. Your accusations say how much you still have to learn. You replies should be reposting every number with questions to better understand those numbers. Instead you are making the classic mistake - thinking subjectively. Not discussing every posted number.
You ignored facts posted previously. Even ignored so many 'whole house' protectors posted yesterday. Previously posted were numbers for any minimally effective protector. You did not even acknowledge that 'learn it or die' fact. AV Doogle also provided a very robust solution.
Posted were benchmarks to identify ineffective protectors. Did you read that? 1) It has no dedicated connection to earth. 2) Manufacturer does not discuss earth ground. If you did, then you know the difference is massive between a plug-in protector and a 'whole house' protector. But your repeated frustration suggests you ignored every number.
Plug-in protectors have no dedicated earth wire (Strike one). The manufacturer does not discuss earthing (Strike two). Its numeric specs make no claims for surge protection (Strike three). See those scary pictures that demonstrate frequent problems only with plug-in protectors (Strike four). The $25 and $150 plug-in protectors have the same protector circuit selling for $7 in a grocery store - because its purpose if profits; not protection (Strike five).
You asked for effective protection. Scary pictures alone show a major difference between plug-in and 'whole house' protectors. But then one is sold for maximum profit. The other is sold by far more responsible companies to provide actual surge protection. Numbers that define protection were also provided. If you grasped the numbers, you would not be so confused. If you posted actual questions with numbers rather than being accusatory, then I might actually believe you are reading before posting.
Somehow you are infatuated with MOVs rather than what makes MOVs so effective. Your replies suggest only superficial reading. Did not read multiple times with enough care to understand the massive difference between plug-in and whole house' protectors.
