Re: [RE-wrenches] Electric fence, metal buildings, lightning protection systems

[Roy Butler]

Erika, That electric fencer needs it's own grounding electrode system! Unlike the premises grounding system, where there's normally no voltage present, the fencer's ground completes the circuit. I have measured over 12,000 volts on our farm fencer grounding conductor....I have learned not to touch it....had to try it 2 or 3 times to be sure though ;-) Roy Butler NABCEP Certified Solar PV Installer® NYSERDA eligible PV & wind installer Four Winds Renewable Energy, LLC 8902 Route 46, Arkport, NY 14807 607-324-9747 www.four-winds-energy.com Join us at the 10th Annual Small Wind Conference A Gathering of Installers, Manufacturers, Dealers, & Distributors June 17 and 18, 2014 in Stevens Point, Wisconsin www.smallwindconference.com Although no trees were killed in the sending of this message, a large number of electrons were terribly inconvenienced.

I wonder what the tolerable window of voltage of + or – to ground is for this unit before it cries GF.   During a drizzle I had a little tingle while assembling EMT. I did not get a meter out, but it sorta felt like a 9V battery across your tongue. In the end even a little tingle is not really supposed to be there…     Regards, Erika   From: jay peltz [mailto:j...@asis.com] Sent: Friday, December 06, 2013 11:05 AM To: er...@repowersolutions.com; RE-wrenches Subject: Re: [RE-wrenches] Electric fence, metal buildings, lightning protection systems   Hi Erika, What seems to be the issue? And what equipment ( inverters ) are you using   Jay   Peltz power   On Dec 6, 2013, at 5:57 AM, "Erika Weliczko" <er...@repowersolutions.com> wrote: Anyone had to contend with electric fence installation (AC controller) using a ground rod (not main service) at remote farm building and messing with inverters? And perhaps causing other issues?   Of course, this is a metal roof with a lightning protection system (i.e. bare braided copper on roof all the way to rod.)   I think we need to redirect the electric fence wire to its own dedicated rods, away from the building that has solar.   Insights are appreciated.   Thanks, Erika   _______________________________________________ List sponsored by Home Power magazine List Address: RE-wrenches@lists.re-wrenches.org Change email address & settings: http://lists.re-wrenches.org/options.cgi/re-wrenches-re-wrenches.org List-Archive: http://lists.re-wrenches.org/pipermail/re-wrenches-re-wrenches.org List rules & etiquette: www.re-wrenches.org/etiquette.htm Check out participant bios: www.members.re-wrenches.org _______________________________________________ List sponsored by Home Power magazine List Address: RE-wrenches@lists.re-wrenches.org Change email address & settings: http://lists.re-wrenches.org/options.cgi/re-wrenches-re-wrenches.org List-Archive: http://lists.re-wrenches.org/pipermail/re-wrenches-re-wrenches.org List rules & etiquette: www.re-wrenches.org/etiquette.htm Check out participant bios: www.members.re-wrenches.org
