[RE-wrenches] Franklin Subdrive SolarPAK
HI All; Anyone have any experience with Franklin Electric's new Subdrive SolarPAK submersible pumps? They're showing 1.5 and 3 Hp options. Its a 3 phase motor powered by an above ground VSD type controller that allows for array direct pumping. This particular project needs about 10,000 GPD at 200 ft of head, so the Grundfos isn't getting it. AEE is carrying them now which is encouraging, as they don't stock fly by night BS. Franklin is also a very respected name in pumping, and I've use their constant pressure controller with a submersible pump in the past with excellent results. (a 1.5 hp pump that overloaded a VFX 3524) Thanks in advance, -- R.Ray Walters CTO, Solarray, Inc Nabcep Certified PV Installer, Licensed Master Electrician Solar Design Engineer 303 505-8760 ___ 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
[RE-wrenches] NEC.pdf
I've been using the electronic version of the NEC, but have not found a way to bookmark pages like you could in the old Folio View versions. There is a section called bookmarks, but it is a table of contents. Is is possible to set up links to commonly used pages?

[RE-wrenches] Rapid shutdown for pole mounts
The rapid shutdown language is so confusing. When looking at the rapid shutdown language, does PV systems on a building refer to only situations where the array is on a building; or does it include DC conductors as well. For example, if the DC conductors from a pole mounted array run up the side of a building before punching in to the inverter, does this require rapid shutdown? Is this PV system considered on a building?

Re: [RE-wrenches] Rapid shutdown for pole mounts
Bill Brooks should probably respond to this also, but reading the NEC, it looks like if the wires do not go inside the building to run more than 5 feet (as the crow flies), the the rapid disconnect does not apply.OR, less than 10 feet from the array IF the PV is mounted on that building. boB On 4/18/2014 1:34 PM, Aaron Mandelkorn wrote: The rapid shutdown language is so confusing.

Re: [RE-wrenches] Rapid shutdown for pole mounts
Aaron, An exterior utility service panel with an underground service lateral is not considered in or on the building. Keep the dc conductors off of the building and you will be fine with a ground-mounted PV system. Don't bring them inside the building, and don't run them along the exterior of the building. The whole requirement is to deenergize conductors that a firefighter might come in contact with while fighting a fire. The most important conductors are those inside the building. A PV array on top of a buiding is also required to deenergize the conductors within 10 feet of the array (PV Output Circuit Conductors). The array is allowed to remain at full voltage.
