<div dir="ltr"><div>Hi William,</div><div><br></div><div>Yes, we have run into this for the past couple of years since the 2020 NEC went into effect 1/1/2023 in CA. At first we thought it was PG&E that had the requirement, but then found out it was the NEC and I believe PG&E will enforce it as well. There was misinformation from electricians who thought that the old "California 4" type panel with two 200 A main breakers was no longer allowed by PG&E. In fact, they are still allowed, but just need to have the 2020 NEC-compliant separate disconnect partiations. </div><div><br></div><div>This is the Siemens brochure with more information: <a href="https://s3.amazonaws.com/dcc-data-extract/new-delta/asset/Compas/daily/Compas/Marketing%20Flyer/SIE_FL_230-71_MeterMain.pdf?100822">https://s3.amazonaws.com/dcc-data-extract/new-delta/asset/Compas/daily/Compas/Marketing%20Flyer/SIE_FL_230-71_MeterMain.pdf?100822</a></div><div><br></div><div>Best,</div><div><br></div><div>August</div><div><div dir="ltr" class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr"><div dir="ltr"><div dir="ltr"><p><br></p></div></div></div></div></div><br></div><br><div class="gmail_quote gmail_quote_container"><div dir="ltr" class="gmail_attr">On Thu, Mar 27, 2025 at 4:22 PM William Miller via RE-wrenches <<a href="mailto:re-wrenches@lists.re-wrenches.org">re-wrenches@lists.re-wrenches.org</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div class="msg-3369843033788245310"><div lang="EN-US"><div class="m_-3369843033788245310WordSection1"><p class="MsoNormal"><span style="font-size:12pt;font-family:Verdana,"sans-serif"">Friends:</span></p><p class="MsoNormal"><span style="font-size:12pt;font-family:Verdana,"sans-serif""> </span></p><p class="MsoNormal"><span style="font-size:12pt;font-family:Verdana,"sans-serif"">I have ordered a Class 320 Meter/Main/Combo.  My vendor informs me there are new codes that apply to these cans, specifically in 230.71(B), cited below:</span></p><p class="MsoNormal"><span style="font-size:12pt;font-family:Verdana,"sans-serif""> </span></p><p class="MsoNormal"><b><span style="font-size:10pt;font-family:"Times New Roman","serif"">(B) Two to Six Service Disconnecting Means. </span></b><span style="font-size:10pt;font-family:"Times New Roman","serif"">Two to six service</span></p><p class="MsoNormal"><span style="font-size:10pt;font-family:"Times New Roman","serif"">disconnects shall be permitted for each service permitted by</span></p><p class="MsoNormal"><span style="font-size:10pt;font-family:"Times New Roman","serif"">230.2 or for each set of service-entrance conductors permitted</span></p><p class="MsoNormal"><span style="font-size:10pt;font-family:"Times New Roman","serif"">by 230.40, Exception No. 1, 3, 4, or 5. The two to six service</span></p><p class="MsoNormal"><span style="font-size:10pt;font-family:"Times New Roman","serif"">disconnecting means shall he permitted to consist of a combination</span></p><p class="MsoNormal"><span style="font-size:10pt;font-family:"Times New Roman","serif"">of any of the following:</span></p><p class="MsoNormal"><span style="font-size:10pt;font-family:"Times New Roman","serif"">(1) Separate enclosures with a main service disconnecting</span></p><p class="MsoNormal"><span style="font-size:10pt;font-family:"Times New Roman","serif"">means in each enclosure</span></p><p class="MsoNormal"><span style="font-size:10pt;font-family:"Times New Roman","serif"">(2) Panelboards with a main service disconnecting means in</span></p><p class="MsoNormal"><span style="font-size:10pt;font-family:"Times New Roman","serif"">each panelboard enclosure</span></p><p class="MsoNormal"><span style="font-size:10pt;font-family:"Times New Roman","serif";background:yellow">(3) Switchboard(s) where there is only one service disconnect</span></p><p class="MsoNormal"><span style="font-size:10pt;font-family:"Times New Roman","serif";background:yellow">in each separate vertical section where there are</span></p><p class="MsoNormal"><span style="font-size:10pt;font-family:"Times New Roman","serif";background:yellow">barriers separating each vertical section</span><span style="font-size:10pt;font-family:"Times New Roman","serif""></span></p><p class="MsoNormal"><span style="font-size:10pt;font-family:"Times New Roman","serif"">(4) Service disconnects in switchgear or metering centers</span></p><p class="MsoNormal"><span style="font-size:10pt;font-family:"Times New Roman","serif"">where each disconnect is located in a separate compartment</span><span style="font-size:10pt;font-family:Verdana,"sans-serif""></span></p><p class="MsoNormal"><span style="font-size:12pt;font-family:Verdana,"sans-serif""> </span></p><p class="MsoNormal"><span style="font-size:12pt;font-family:Verdana,"sans-serif""> </span></p><p class="MsoNormal"><span style="font-size:12pt;font-family:Verdana,"sans-serif"">Here is an analysis,
