| Surge protection for amps? Even though minimal and effective protect is 50,000 amps and costs about $1 per protected appliance. Even though Shunyata Resarch spec numbers do not even claim to protect from potentially destructive surges. | |
| Surge protection for amps? If a surge (ie 20,000 amps) connects harmlessly low impedance to earth, well, an IEEE Standard defines that as 99.5% to 99.9% protection. Only then can a plug-in (ie series mode) protector do something useful - add maybe 0.2% additional protection... | |
| Surge protection for amps? Works well? How many other appliances, not on a Brickwall, are destroyed? Since a potentially destructive surge never happened, then it works well? If it works well, then a furnace, dimmer switches, dishwasher, door bell, LED and CFL bulbs, centra... | |
| Surge protection for amps? I think I’m going to look at the whole house option. I just need to figure out which one is best for my needs. Effective protector does not do protection. Best protectors connect low impedance (ie less than 10 feet) to what actually and harml... | |
| Environmental Potentials whole house surge protection, can I get your opinions? Again you ramble on about things completely irrelevant to the OP's questions. Refuse to learn how protection really works. Apparently foolishly assume everything about electricity is defined by the NEC. And repeatedly make adversarial denials wi... | |
| Environmental Potentials whole house surge protection, can I get your opinions? Do NEC codes protect property from *all* hazards - as you have only assumed? Of course not. Codes only protect property from hazards that also threaten human life - such as fire. Appliances can be completely destroyed by other anomalies. NEC says ... | |
| Environmental Potentials whole house surge protection, can I get your opinions? NFPA is a human protection code; insufficient for transistor protection. Transistor protection both *meets* and *exceeds* those human safety requirements.Human safety discusses resistance. Transistor safety also addresses impedance and equipotenti... | |
| Environmental Potentials whole house surge protection, can I get your opinions? I have yet to hear of a residential electrical contractor that checks for earth resistance. No standard was defined to measure that resistance. A 25 ohm number is too subjective Rather than play games with local inspectors, electricians routinely... | |
| Environmental Potentials whole house surge protection, can I get your opinions? Soil conductivity (resistance) is relevant for code requirements - that only address human safety. Grounding for appliance safety is why Ufer grounding (to exceed code requirements) is popular. Earthing for protection is an art.Earth ground for pr... | |
| Environmental Potentials whole house surge protection, can I get your opinions? As my house is almost 100 years old, is there any way to test a ground? Or, is there any way to add a newer/more effective ground? A utility demonstrates what must exist with good, bad, and ugly (preferred, wrong, and right) solutions in Tech T... | |
| Environmental Potentials whole house surge protection, can I get your opinions? If isolation transformers did that protection, then a utility transformer that provides AC power means no anomalies exist. Other potentially destructive anomalies act just like lightning. We simply use lightning as an example of all other potent... | |
| Environmental Potentials whole house surge protection, can I get your opinions? Maximum Surge Current:6,500 Amps Response Time:1 nanosecond Spike Clamping Voltage:188 VAC peak @ 3,000 Amps More effective protectors use L-N, L-G, and G-N protection. Furman only uses L-N. Does not matter. They are selling to people who have no ... | |
| Environmental Potentials whole house surge protection, can I get your opinions? If warranty proved anything, then GM products have always been superior to Honda and Toyota. Good luck getting every GM warranty honored. Dealers,. too often, get stuck with costs. So dealers will do anything to avoid honoring that warranty.A l... | |
| Environmental Potentials whole house surge protection, can I get your opinions? I’m not sure why you call fuses a "myth." Those that deny do not even read what is posted. Only read what they want to read. Nobody said a fuse is a myth. Defined is the "fuse myth". Quoted so that what was posted might be read this time:For exam... | |
| Environmental Potentials whole house surge protection, can I get your opinions? A fuse provides "protection" and earth ground has nothing to do with its effectiveness. And your reference to " hundreds of thousands of joules" is an arbitrary figure. Obvious is when one recites hearsay. For example, a fuse myth is promoted su... |
