The answer is provided by <g id=\"gid_3\">VDE 1000-10<\/g>, supplemented by other relevant regulations. Here are <strong data-start=\"705\" data-end=\"726\">5 key facts<\/strong> that those responsible in companies should know:  <\/p>\n<hr data-start=\"780\" data-end=\"783\">\n<h3 data-start=\"785\" data-end=\"847\">1\ufe0f\u20e3 <strong data-start=\"793\" data-end=\"847\">The electrical specialist is bound by professional instructions<\/strong><\/h3>\n<p data-start=\"848\" data-end=\"1103\">The ES must not work &#8220;at will&#8221;. They are always technically subordinate to a chief <g id=\"gid_0\">responsible electrical specialist (CRES)<\/g> &#8211; if one has been appointed. This person is responsible for the safe organization of electrical work.  <\/p>\n<hr data-start=\"1105\" data-end=\"1108\">\n<h3 data-start=\"1110\" data-end=\"1187\">2\ufe0f\u20e3 <strong data-start=\"1118\" data-end=\"1187\">Disciplinary and technical subordination are not identical<\/strong><\/h3>\n<p data-start=\"1188\" data-end=\"1482\">In disciplinary terms, the ES may report to the CTO or a production manager, for example. However, the CRES has sole technical responsibility &#8211; <strong data-start=\"1332\" data-end=\"1405\">for all matters relating to electrical safety and technical assessment<\/strong>. This prevents dangerous misjudgements by non-electrical engineers. <\/p>\n<hr data-start=\"1484\" data-end=\"1487\">\n<h3 data-start=\"1489\" data-end=\"1533\">3\ufe0f\u20e3 <strong data-start=\"1497\" data-end=\"1533\">Without CRES, the contractor is liable<\/strong><\/h3>\n<p data-start=\"1534\" data-end=\"1746\">If no CRES is appointed, the full electrotechnical responsibility lies with the contractor himself. In the event of accidents, this can have fatal legal consequences &#8211; from recourse claims to criminal prosecution. <\/p>\n<hr data-start=\"1748\" data-end=\"1751\">\n<h3 data-start=\"1753\" data-end=\"1821\">4\ufe0f\u20e3 <strong data-start=\"1761\" data-end=\"1821\">The &#8220;electrical specialist&#8221; status is not permanently valid<\/strong><\/h3>\n<p data-start=\"1822\" data-end=\"2058\">Specialist knowledge is <strong data-start=\"1840\" data-end=\"1877\">tied to the state of the art<\/strong>. Anyone who does not regularly pursue further training loses this status &#8211; even with training and professional experience. <strong data-start=\"1988\" data-end=\"2023\">Specialist knowledge must be maintained<\/strong>, not just acquired once. <\/p>\n<hr data-start=\"2060\" data-end=\"2063\">\n<h3 data-start=\"2065\" data-end=\"2154\">5\ufe0f\u20e3 <strong data-start=\"2073\" data-end=\"2154\">In-house training is also possible &#8211; but must be documented<\/strong><\/h3>\n<p data-start=\"2155\" data-end=\"2336\">Not all training has to be external.
