1. [Amps] MOV Sizing (score: 1): Author: "Paul Christensen" <w9ac@arrl.net>; Date: Sat, 3 Mar 2007 07:41:00 -0500; I am planning on adding a set of MOVs to the AC line of a recently acquired Alpha 86 amplifier. I have reviewed Littlefuse's MOV Applications Guide but I am still a bit unclear as to the optimum clam; /archives//html/Amps/2007-03/msg00020.html (6,944 bytes)
2. Re: [Amps] MOV Sizing (score: 1): Author: "Robert B. Bonner" <rbonner@qro.com>; Date: Sat, 3 Mar 2007 11:35:13 -0600; Paul, The two to ground would be the correct installation. 140V should be very adequate I would think. Keep them up off the chassis because sometimes they blow BLACK and SOOTY. If you notice in many; /archives//html/Amps/2007-03/msg00023.html (8,558 bytes)
3. Re: [Amps] MOV Sizing (score: 1): Author: rgroh@swbell.net; Date: Sat, 3 Mar 2007 12:12:52 -0800 (PST); Just had a thought on this subject - there are 'whole' house ac line surge protectors - industrial type - that are intended to be connected directly on the side of the the house breaker box. One sour; /archives//html/Amps/2007-03/msg00028.html (10,597 bytes)
4. Re: [Amps] MOV Sizing (score: 1): Author: "Phil Clements" <philc@texascellnet.com>; Date: Sat, 3 Mar 2007 14:24:53 -0600; Good thought, good solution, Bob. I installed a Waber Power Master unit on my service entrance panel when I built the ham shack several years ago. This protects everything, and saves having to put M; /archives//html/Amps/2007-03/msg00030.html (8,361 bytes)
5. Re: [Amps] MOV Sizing (score: 1): Author: "Paul Christensen" <w9ac@arrl.net>; Date: Sat, 3 Mar 2007 15:29:37 -0500; Bob & Bob, Good suggestions. I plan on adding a "whole house" TVSS or MOV unit in the near future. There's a lot of product out there. One personal reply I received from someone in the surge suppress; /archives//html/Amps/2007-03/msg00032.html (11,632 bytes)

Re: [Amps] MOV Sizing (score: 1): Author: "Tom W8JI" <w8ji@w8ji.com>; Date: Sat, 3 Mar 2007 18:05:13 -0500; MOV's should never tie to the safety ground lead or any ground lead outside of an entrance panel. They can have very large fault currents and, if sized to close to the power line voltage, can go into; /archives//html/Amps/2007-03/msg00036.html (7,710 bytes)
7. Re: [Amps] MOV Sizing (score: 1): Author: "Paul Christensen" <w9ac@arrl.net>; Date: Sat, 3 Mar 2007 20:30:55 -0500; That makes a lot of sense. Some of the sources I've read recently advocate not using ground as a MOV reference for that very reason. High current surges may follow other grounding paths (coaxial cab; /archives//html/Amps/2007-03/msg00041.html (8,004 bytes)
