Power surges often accompany power outages.

Surges are quite rare. One might happen every seven years. Most will not see one in twenty years.

A surge can cause a blackout. But most blackouts are not created by surges.

Best protection from surges is already inside all appliances. That existing internal protection is typically superior to what is marketed in magic plug-in boxes. How does that 'plug-in box' 2 cm protector part 'block' what three miles of sky cannot? How does its paltry thousand joules 'absorb' a surge that can be hundreds of thousands of joules.  They are selling a $3 power strip with five cent protector part for $25 or $80.  It protects profit margins; not appliances.

Being so grossly undersized, its protector parts must disconnect as fast as possible.  Leaving a surge fully connected to appliances.  No problem.  A surge is too small to overwhelm superior protection inside appliances.  Then the naive claim, "My protector sacrificed itself to save my fridge / computer / TV ..."  Total bull.

If that surge is incoming to a protector, at the exact same time it is also outgoing into and through attached appliances.  It is electricity.  It only exists when that outgoing path also exists at the exact same time.  Nothing does protection by sacrificing.

Worse, those internal protector parts, sometimes, do not disconnect fast enough.  Then this happens: https://imgur.com/hwCWHMW ..


Protection only exists when hundreds of thousands of joules dissipate harmlessly outside in earth.  Doing what Franklin demonstrated over 250 years ago.  Standard in facilities that could not have damage over 100 years ago.  Informed consumers spend about $1 per appliance for this best and superior protection.  That comes from other companies known for integrity.  That protects all appliances (dishwasher, clock radio, central air, LED & CFL bulbs, refrigerator, recharging electronics, computers, GFCIs, furnace, modem, doorbell, smoke detectors). So that nobody even knew a surge existed.  That must remain functional for many decades even after many direct lightning strikes.  That is unknown by most who are only educated by hearsay, wild speculation, and advertising propaganda.  That even comes with numbers that claims effective protection.  

Lightning is typically 20,000 amps.  So a minimal 'whole house' protector is 50,000 amps.  Effective protectors do not fail.  Profit centers do.

Protectors never do protection.  Scam protectors fail on surges incoming to all appliances but damaging none.  (If a surge is incoming to any appliance, it is incoming to all appliances.)

Effective protectors are connecting devices to what harmlessly dissipates (this number is critical) hundreds of thousands of joules.  That is single point earth ground.  Those earthing electrodes must both meet and exceed what is required by code.  That protector must connect low impedance (ie less than 10 feet) to those electrodes.  Only then is a surge not anywhere inside a house.  Only then are all appliances protected.  Only then does that consumer spend tens or 100 times less money for protection that actually works.  Only then are all plug-in protectors (rated at near zero joules) protected so that this does not happen : http://www.nj.com/hunterdon-county-democrat/index.ssf/2013/10/house...

Blackouts are created by many things.  One rare reason is a surge.  However many other surges also exist and do not create a blackout.  Caused by a stray car, utility switching, tree rodents, wind, and linemen errors.  Informed consumers do what was the only proven solution even over 100 years ago.  Properly earth only one 'whole house' protector from companies known for integrity.  Because a protector is only as effective as its low impedance (ie less than 10 foot) connection to and the quality of single point earth ground.  (Obviously wall receptacle safety ground is not earth ground.)



What most needs protectoin if a surge exists? Those high profit, tiny joule, plug-in protectors that do not claim protection from any typically destructive surge. That claim protection inferior to what is already inside appliances.
