William, I stand corrected. Thank you.
This is not a supply side tap. I should have said it was a tap on the supply side of the panelboard main breaker. That said , I think it works and meets code, provided the conductors spliced to the feeder are properly sized. The panelboard busbar is protected by it's main breaker and cannot be overloaded by the solar contributuion. On your other point, Milbank makes a 200 amp MMC that that can be retrofitted with a 100 amp breaker. I have done this twice, but not because of a solar install. We've had a couple 100 Amp, 300', underground service laterals that required oversized conductors because of voltage drop. The Milbank 100 Amp equipment is physically too small to do this. In both cases we replaced the very expensive 200 amp breaker with an also very expensive 100 amp breaker, all by Milbank and labeled as such. I was told by my supplier it was impossible to purchase a 200 amp Milbank MMC with the 100 A breaker preinstalled. The 100 A breaker is the same physical size as the 200 and fits right in, no modifications required. I have two 200 amp Milbank breakers on my shelf if you need them. The MMC units are very expensive to begin with. Here in VT / NH a basic meter only enclosure is more often pared with a separate disconnect enclosure through an offset or straight nipple. This combination might work for you, substituting a load center for the disconnect. Dick Ratico Solarwind Electric --- You wrote: Dick: I disagree with your plan. To qualify as a supply side tap, the tap needs to be on the supply side of the main disconnecting means, If I understand your plan correctly, your suggestion does not achieve this. --- end of quote --- _______________________________________________ List sponsored by Home Power magazine List Address: RE-wrenches@lists.re-wrenches.org Options & 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
