We are seeing problems with the equipment needed to implement a safety requirement. That observation does not logically conclude the safety requirement is not valuable.</span></p><p class="MsoNormal"><span style="font-family:"Verdana","sans-serif";color:#1f497d"> </span></p><p class="MsoNormal"><span style="font-family:"Verdana","sans-serif";color:#1f497d">I hesitate to dismiss any safety requirement out of hand. Safety systems are designed to save lives and protect from injury, and most of them do. I am glad to have anti-lock brakes, smoke detectors and air bags. I have also found it quite handy to initiate RSS to allow me to work more safely on solar circuits.</span></p><p class="MsoNormal"><span style="font-family:"Verdana","sans-serif";color:#1f497d"> </span></p><p class="MsoNormal"><span style="font-family:"Verdana","sans-serif";color:#1f497d">Does anyone on this installers forum have contacts in the fire-response community that can comment on the their side of the issue? If RSD is really necessary for safety, then I will do my best to install good equipment properly and hold manufacturers accountable for shoddy solutions. If RSD is not that effective we need to discuss undoing the code requirements.</span></p><p class="MsoNormal"><span style="font-family:"Verdana","sans-serif";color:#1f497d"> </span></p><p class="MsoNormal"><span style="font-family:"Verdana","sans-serif";color:#1f497d">Sincerely,</span></p><p class="MsoNormal"><span style="font-family:"Verdana","sans-serif";color:#1f497d"> </span></p><p class="MsoNormal"><span style="font-family:"Verdana","sans-serif";color:#1f497d">William Miller</span></p><p class="MsoNormal"><span style="font-family:"Verdana","sans-serif";color:#1f497d"> </span></p><p class="MsoNormal"><span style="font-family:"Arial","sans-serif";color:#1f497d">Miller Solar</span></p><p class="MsoNormal"><span style="font-family:"Arial","sans-serif";color:#1f497d">17395 Oak Road, Atascadero, CA 93422</span></p><p class="MsoNormal"><span style="font-family:"Arial","sans-serif";color:#1f497d">805-438-5600</span></p><p class="MsoNormal"><span style="font-family:"Arial","sans-serif";color:#1f497d"><a href="http://www.millersolar.com/"><span style="color:blue">www.millersolar.com</span></a></span></p><p class="MsoNormal"><span style="font-family:"Arial","sans-serif";color:#1f497d">CA Lic. 773985</span></p><p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1f497d"> </span></p><p class="MsoNormal"><span style="font-family:"Verdana","sans-serif";color:#1f497d"> </span></p><p class="MsoNormal"><b><span style="font-size:10.0pt;font-family:"Tahoma","sans-serif"">From:</span></b><span style="font-size:10.0pt;font-family:"Tahoma","sans-serif""> RE-wrenches [mailto:<a href="mailto:re-wrenches-bounces@lists.re-wrenches.org">re-wrenches-bounces@lists.re-wrenches.org</a>] <b>On Behalf Of </b>david quattro via RE-wrenches<br><b>Sent:</b> Saturday, February 15, 2025 6:05 AM<br><b>To:</b> RE-wrenches<br><b>Cc:</b> david quattro<br><b>Subject:</b> Re: [RE-wrenches] Tigo inverter experience</span></p><p class="MsoNormal"> </p><div><p class="MsoNormal">RSD is the worst thing to happen to solar.
