Protector and that plug-in UPS does not stop, block, or absorb surges - except in myths. Will a protector or plug-in UPS stop or block what miles of air could not?
Of course not. Shunt mode protectors are not effective dams or surge absorbers. They are only temporary shunts - connection, short circuit, diverter - that connects an incoming surge less than 10 feet to earth ground - the protection. Why do we need such protectors? So that internal protection inside properly designed appliances is not overwhelmed. A surge must be connected to protection before it can enter the building.
An effective MOV protector connects that surge less than 10 feet to protection. Anything that can work adjacent to that appliance is typically already inside that appliance. This explains why both cheap actually grossly overpriced power strip protectors and plug-in UPSes don't provide effective protection.
Without the less than 10 foot connection to earth, then where is that destructive surge to be shunted to? In the meantime, computer power supplies must have some of the most resilient internal protection, as even demanded by Intel specifications. Protection that assumes a destructive transient will be earthed before transient can enter the building.
Review detailed numerical specs for a plug-in UPS. It provides same protection circuits found in power strip protectors. Notice the joules.
Joules mean both power strip and UPS utilize the same protection circuit. Many big name, plug-in UPSes are even grossly undersized - too few joules - ineffective protection. But then a plug-in UPS manufacturer does not even claim to protect from a destructive type of surge.
Read his detailed numerical specs - if manufacturer even provides detailed specs. To protect an adjacent appliance, the protector must stop, block, or absorb the transient. But those are shunt mode protectors. They don't even claim such 'blocking' abilities. Shunt mode protectors are effective when connected 'less than 10 feet' to the same earth ground that all other incoming utilities connect to. This is how ham radio operators even in the early s discovered effective protection.
Earthing - and not a plug-in protector - is the protection. Cheap power strip surge protectors don't protect much; nor do they claim to. Plug-in protectors cannot claim to provide that protection because the short, direct, and independent earth ground connection does not exist. Plug-in UPSes typically use a same protector circuit. They also do not stop or block destructive transients. Most power strips have a power switch that contains a red indicator lamp; by looking at the lamp, you can easily tell if the strip is on or not.
The lamp glows only when the strip is connected to a live outlet and the power switch is on. Power strip manufacturers use neon lamps because they're inexpensive, relatively durable and run directly off the volt AC found in commercial electric power.
Neon bulbs run cool and consume very little electricity -- typically a fraction of a watt. Neon itself glows with an orange color; a tinted plastic cover may give the lamp a red appearance. The easiest way to avoid power surge problems is to unplug devices that aren't being used. Upgrade inadequate wiring. Fix overloaded circuits. Sounds the same as a surge protector , doesn't it? But it actually works a different way. Most fuses are very thin pieces of wire designed to allow only so much current through them.
The thicker the wire, the more current can flow; so fuses rated for higher currents usually have thicker pieces of wire inside them. Yeah it can be repaired , but it depends on which method you choose.
As the surge protector covers the sensitive devices and protect it from electrical surges , it needs to be handle with proper care. Breakers are designed to ignore surges and transients, anyway.
Whether there' on the same outlet or not doesn't matter if they're on the same breaker. Sometimes that breaker might also be shared with an adjoining room where you have other loads. The best way to test an electrical outlet for power surges is with a surge protector. Obtain a surge protector with an internal breaker.
Plug the surge protector into the outlet. Check the surge protector periodically to see if the circuit breaker has tripped. What does blinking light on power strip mean? Category: technology and computing computer peripherals. The ubiquitous power strips used in every type of home or office have a tendency to flicker caused by the slow deterioration of the indicator light.

When to Use a Surge Protector Oct 15, Common Causes of Power Surges Overloaded Outlets Plugging too many devices into one outlet, or multiple outlets in one room, can lead to home electrical fires. Faulty Wiring If your home is older, or your wiring has not been updated in over 30 years, you are at risk for power surges.
High-Energy Appliances Your refrigerator and air conditioner are great examples of high-energy appliances. Power Outage When an entire neighborhood or city loses power, your home becomes extremely susceptible to power surges.
