[RE-wrenches] SDHW Anti-Scalding Valve
Folks, In California, for a single DHW system serving a multiple unit building; DHW is a storage tank with indirect heating via an internal heat exhanging loop; heating loop supplied by high temp (145 deg) gas fired boiler; Is an anti-scalding valve required on the output of the storage tank? If so, by what authority? If a solar heated storage tank (drain back) is installed ahead of the main storage tank, does that change the requirements?

[RE-wrenches] Square D 225A load center
Greetings all! I heard that Square D makes a load center with a 225A buss bar and a 200A main breaker - ideal for installing 60A of solar interconnection breakers. Does anyone have a part number (or any other info) on this item? Thanks! Andrew Truitt Standard Solar -- Don't get me wrong: I love nuclear energy! It's just that I prefer fusion to fission. And it just so happens that there's an enormous fusion reactor safely banked a few million miles from us. It delivers more than we could ever use in just about 8 minutes.

Re: [RE-wrenches] Insurance classification
Wrenches, Our insurer has stated this: There is a SOLAR ENERGY CONTRACTORS classification ISO uses the number 99080, if he asked about a renewable Energy Installer then the company may have not been looking for the correct classification. Also his insurer may use their own classification numbers and names. If that is the case then the HVAC class may charge the same rate as SE Contractors. Also you are listed correctly; the classification applies to all works including heating, cooling and power generation. A separate classification needs to be listed for sales of solar equipment; if you look on your Commercial GL coverage part of the policy it lists Stores class code 18437 this is to pick up any direct sales that you would have for parts or equipment that you don't install.

What is the date that the system was placed into service such that it can serve the purpose for which it was built? Note that the date is the date on which the system is capable of serving the purpose, regardless of whether or not the owner chooses to use the system for that purpose. In this case, backfeeding a net meter is clearly part of the purpose of the system. As such the system cannot be placed into service until the net meter is in place. Hold off on the interconnection until January. Of course, this is all strictly a matter which can only be discussed between the owner and his tax advisor. :-) Mark Frye Berkeley Solar Electric Systems 303 Redbud Way Nevada City, CA 95959 (530) 401-8024 www.berkeleysolar.com http://www.berkeleysolar.com/ From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Kirpal Khalsa Sent: Wednesday, December 03, 2008 11:00 AM To: RE-wrenches Subject: [RE-wrenches] system commissioning time frames Greetings..we recently installed a solar pv system on a residential customer and it has been inspected by both the local electrical inspector and the state rebate authority and approved. Now that we have passed those inspections, the next phase of the process is having the utility company come out and install their new meter for net metering..I was wondering if anyone has a definitive answer as to what actually commissions the system? We are thinking of having the power company hold off until after the new year so that the customer can get the 2009 tax credits instead of the 2008 credits... The question is does the system get commissioned once it is inspected or once the power company gets the new meter installed so that the system can actually be turned on.

[RE-wrenches] Inter-row shading calculator
Friends: We have a number of resources on our web site available to anyone who wishes to use them. One is an Inter-row shading calculator based on an Excel spreadsheet. It came to my attention recently that there was a flaw in this calculator. I have since repaired the flaw and I have re-posted the corrected spreadsheet. My apologies if anyone was lead astray by the error, but at least the error favored greater spacing. If anyone wishes to check this spreadsheet against their own trigonometry, I would be grateful. The page is: http://mpandc.com/resources/resources.html -- find the Inter-row shading spreadsheet. The sheet is protected but there is no password. If you find it handy, drop me a line. If you pass it on, keep my name on it.

Re: [RE-wrenches] Square D 225A load center
Almost right Christopher. NEC 705.12(2) allows the ratings of the overcurrent devices supplying power to the bus bar to be 120% of the busbar rating. For a 225-amp busbar that amounts to 270 amps. So a 200-amp main breaker and a 70-amp back fed breaker from the solar system. Or a 225-amp main breaker and a 45-amp back fed breaker from the solar system. Christopher Freitas wrote: Ahhh – I think I get it – you get the 20% of the 200 amps (so 40 amps) + the extra 25 amps because the buss is only running at 200 amps?
