Get a UPS and make sure you have properly grounded outlets.
"volts500" wrote in message om... "Dorot29701" wrote in message ... I live in FL. Every so often when I get my monthly bill, there is a notice in it that I can get "whole house" surge protection. I never bothered with that because I had surge protectors for computers, TVs, DVDs etc. This week we have had three power outages. The weather was fine - at least right here - when suddenly there was this off, on, off again, on again and then it stayed off. All very quick. My appliances are okay but my neighbor lost his computer - even though he has a surge protector. Last year I lost a DVD and VCR during a bad storm...but these recent outages weren't weather related. Now I worry about large appliances - don't have anything protecting them. How susceptible are they to surges? Do they have any kind of built in protection? Is it cost effective to get this "whole house" surge protection from the power company? Thanks for any help. Dorothy Surge protection starts with a properly installed, _effective_ power grounding electrode system. It's critical that the telephone primary protector ground and cable TV system ground, or any other system ground for that matter, be bonded to an effective electric power grounding system. If you have cable TV, since you've already lost a VCR.......I think that you may find that your cable TV is not properly grounded to the electric system ground. Properly bonding all systems (power, phone, cable TV, etc.) together goes a long way towards protection. In fact, manufacturer's usually state in their warranties that a properly grounded system must exist for the warranty to have effect. I don't know about Florida Power, but TECO will not hook up a service without lightning protection installed. I don't believe Florida Power has a surge protection program per se, but TECO has the "Zap Cap" program. The whole house surge protector helps protect major appliances.....and that's part of the warranty. Electronic equipment is required also to have a point of use protector by TECO. IMO, the point of use protector will pick up any surges that get past the whole house protector and any surges created inside the house by other equipment. Here's their webpage: http://www.zapcap.com/ZCHmHm.html Before buying surge protection, I recommend to _always_ read the warranty fine print.........one particular surge protection manufacturer, for example, reserves the right to have any damaged equipment shipped to _them_, at their option. That might be OK for a VCR, but a 200 pound Sony TV could be an obstacle and an expense that comes out of _your_ pocket. An option to the Zap Cap program is to hire an electrical contractor who knows system grounding/lightning protection to check your grounding system, and have them install a whole house protector, then purchase decent point of use protectors like Panamax or Triplite. Remember that if a piece of equipment, such as a computer, which has phone and/or cable connections, that _those_ systems must _also_ be protected by the point of use protector. See TURTLE's post for further protection. OK, _W_Tom :-) |

Surge protection requires earth ground. Safety ground of
those outlets does not provide an earth ground necessary for effective surge protection. Therefore that plug-in UPS only protects from power loss - does not protect hardware. To understand why outlets are not earth ground, one must first learn the concepts of impedance - not the same as resistance. Read that UPS specification. It does not even claim to provide protection from typically destructive surges. It claims the exact same protection found in power strip surge protectors.
