t. Ulitmately my customer agreed with me that this was an undesirable constraint on the operation of an otherwise reliable grid-tied system and it was not clear that this would satify the warranty issue. Mark Frye Berkeley Solar Electric Systems 303 Redbud Way Nevada City, CA 9595

Re: [RE-wrenches] Generator and Enphase

e 400A ATS will see the same 480A of supply breakers as the conductors and busbar of the 400A load center. Here is where I am taking leap of faith that the AHJ will agree with me that the same 120% allowance given to the conductors and load center will be given to ATS itself. Mark Frye Berkeley Sola

Re: [RE-wrenches] sizing a sub-panel used to combine multiple inverter outputs

I think Kent and I agree. For the case where the subpanel is not dedicated a PV sub-panel he is calculating for 2 - 50A breakers and I calculated for 3 - 50A breakers. Mark Frye Berkeley Solar Electric Systems 303 Redbud Way Nevada City, CA 95959 (530) 401-8024 <h

Re: [RE-wrenches] sizing a sub-panel used to combine multipleinverter outputs

Opps! My bad, I was thinking of a single phase system, not the three phase system shown in the article. For the three phase system Kent is correct in counting 180A of supply per bar. Mark Frye Berkeley Solar Electric Systems 303 Redbud Way Nevada City, CA 95959 (530) 401-8024 <h

Re: [RE-wrenches] sizing a sub-panel used tocombinemultipleinverter outputs

not exceed the allowance for the feeder or the sub-panel. Still, if you do have loads in the subpanel, you have to up sizes the sub-panel, but not the feeder conductor. Mark Frye Berkeley Solar Electric Systems 303 Redbud Way Nevada City, CA 95959 (530) 401-8024 <http://www.berkeleysolar.

C side of these inverters we need more to concern ourselves with continuous overload conditions and not so much with short-circuit/ground fault conditions? Mark Frye Berkeley Solar Electric Systems 303 Redbud Way Nevada City, CA 95959 (530) 401-8024 <http://www.berkeleysolar

Re: [RE-wrenches] Expansion joints

Are there any usage charts to tell you when or how to use expansion joints in EMT? The NEC has one for PVC, but what do you refer to for EMT? Best regards, Mark Dickson, NABCEP Certified Solar PV Installer T Oasis Montana Inc. _ From: re-wrenches-boun...@lists.re

This stuff is great! http://www.eternabond.com/DoubleStick-p/cr-ds.htm . Hint: stick it in the freezer and then trim it to size with shears. Also, make sure you got it in the right place before you stick it down! Best regards, Mark Dickson, NABCEP Certified Solar PV Installer T Oasis
