[QUOTE="bud--, post: 1440287, member: 225548"] Excellent information on surges and surge protection is at: [url]http://www.lightningsafety.com/nlsi_lhm/IEEE_Guide.pdf[/url] - "How to protect your house and its contents from lightning: IEEE guide for surge protection of equipment connected to AC power and communication circuits" published by the IEEE in 2005 (the IEEE is a major organization of electrical and electronic engineers). And also: [url]http://www.eeel.nist.gov/817/pubs/spd-anthology/files/Surges%20happen!.pdf[/url] - "NIST recommended practice guide: Surges Happen!: how to protect the appliances in your home" published by the US National Institute of Standards and Technology in 2001 The IEEE surge guide is aimed at people with some technical background. My TV died yesterday. Musta been a surge. Fine print is necessary. Nonsense. Both the IEEE and NIST surge guides say plug-in protectors are effective (but not likely against a direct lighting strike to the house). Nonsense. Neither service panel or plug-in protectors work by "blocking" or "absorbing". As explained in the IEEE surge guide (starting page 30) they primarily work by limiting the voltage from each wire (power and signal) to the ground at the protector. The voltage between the wires going to the protected equipment is safe for the protected equipment. When using a plug-in protector all interconnected equipment needs to be connected to the same protector. External connections, like coax also must go through the protector. Nonsense. A protector at the service panel protects from surges coming into the house on the power service wires. This was a direct lightning strike to the house - a service panel protector does not protect from that. [/QUOTE]
