First, even 120 volts (Ground to Neutral) must cause no electronics damage; create no havoc. Second, those numbers will change with changing loads. Better (more informative) numbers come from putting at least 1400 watts of load (consumption) on that circuit. Then making measurements...

APCs are made as cheap as possible. Even noise will cause it to trip into battery backup mode. Making it trip so often actually increases sales. Gets naive consumers to assume a problem exists (where it does not) and then recommend the miracle solution. How often are your bulbs dimming...

A power supply inside every electronics must do better AVR. The purpose of every power supply design is AVR. Incandescent bulbs must dim to 50% intensity. And electronics must still work just fine. Electronics already contain superior AVR.

It already exists in amp. To filter audio noise requires chokes and transformers that are tens of pounds. So electronics do even better with active filter designs. Much less expensive. No more 20 and 50 pound transformers. Filtering is superior.

Your posts worry about anomalies different from what is in the title - a surge. Appreciate basic concepts before accepting anything as knowledge. For example, 1) if a fuse can stop a surge, well, how does it stop something that is done in microseconds. Fuses take milliseconds or seconds...

The words 'good' and 'monster' are antonyms. Unless ‘good scams’ are part of your vocabulary. Monster has a long history of identifying scams. Then selling a similar product for even higher profits. Read numbers even found on Monster's box. A 330 let-through voltage means it does...

Noise means a current incoming on one wire. And outgoing via another. For example, a defect could exist on the incoming wire. But disconnecting that outgoing wire causes the symptom (noise) to disappear. A solution starts by identifying both wires. Only then can the defect on one of those...

Code has been that standard. If a wall receptacle will accept that plug, then wiring attached to that receptacle is more than sufficient. An earth ground is separate from household wiring. Earth grounds that were installed pre 1990 may not have been sufficient for transistor safety. May...

Upgrading interior wires will do nothing. Protection is always about what exists at the service entrance. The always critical earth ground. Europeans may be confused because safety ground is often confused with a completely different earth ground. Safety ground is irrelevant to surge...

Correctly described were Tripplite, Belkin, Monster, etc protectors. Do not claim to protect from typically destructive surges. Read manufacturer specs. No protection claims. Only profit centers. However, for over 100 years, direct lightning strikes were made irrelevant by properly...

Their profit margins are so obscene that they could send you three more power strips. And still make a healthy profit. Those power strip protectors are marketed to the most naive. A $3 power strip with some then cent protector parts selling for $60 or $100. And it does not even claim to do...

Computers have layers of protection. One of those layers is the safety ground. Eliminating that protection layer is like disabling the rear brakes on you car. After all, front brakes do almost all the stopping anyway. Everything still works fine, until .... One problem created by a...

Lightning rods typically protect only the 60 degree cone beneath it. And do less if the earthing is not significant. A direct lightning strike down to the street to AC utility wires is a direct lightning strike to your electronics. No lightning rods protect from the more typical direct...

Of course there is. Series mode filters. To do that, filters are quite heavy. Some products are Zerosurge, Brickwall, and Surgex. Meanwhile, that is the job of the power supply inside the amp. Making noise and voltage anomalies irrelevant is best and easiest done inside its supply...

Tie a knot in the power cord. Then you may have the same filtering. Spend $4 for the same convenient power strip - without the 1000% profit margin. Furman demonstrates what Monster Cable did when selling $7 speaker wire for $70. Monster told consumers that speaker wire had polarity...
