This article explains the requirements, inspection intervals, the difference between stationary and portable equipment, and the inspection process.<\/p>\n<h2>Key Points at a Glance<\/h2>\n<ul>\n<li>The DGUV-V3 inspection is based on the <strong>DGUV Regulation 3<\/strong> \u201eElectrical Systems and Equipment\u201c (formerly BGV A3).<\/li>\n<li>She is <strong>Obligation<\/strong> For all companies that have electrical equipment in the workplace.<\/li>\n<li>A distinction is made between <strong>portable<\/strong> and <strong>stationary<\/strong> Equipment with different inspection intervals.<\/li>\n<li>The test is conducted using a <strong>Certified Electrician<\/strong> in accordance with VDE 0701-0702 standards.<\/li>\n<li>The deadlines are <strong>Guidelines<\/strong> \u2013 The risk assessment and the error rate are the key factors.<\/li>\n<\/ul>\n<h2>What is the DGUV-V3 inspection?<\/h2>\n<p>The <strong>DGUV-V3 Inspection<\/strong> Regular safety inspections of electrical systems and equipment in accordance with the <strong>DGUV Regulation 3<\/strong>. It ensures that electrical equipment does not pose a hazard to employees. The inspection includes a visual inspection, measurements (e.g., protective conductor resistance and insulation resistance), and a functional test.<\/p>\n<h2>Is the DGUV-V3 inspection mandatory?<\/h2>\n<p>Yes. The obligation arises from the <strong>DGUV Regulation 3<\/strong> in connection with the <strong>Industrial Safety Regulation<\/strong> and the Occupational Safety and Health Act. Every employer must have electrical equipment inspected before it is first put into service and at regular intervals thereafter.<\/p>\n<h2>Portable vs. Stationary Equipment<\/h2>\n<p>The inspection intervals depend on the type of equipment:<\/p>\n<figure class=\"wp-block-table\">\n<table>\n<thead>\n<tr>\n<th>Type<\/th>\n<th>Examples<\/th>\n<th>Guideline: Test Period<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td><strong>Portable Equipment<\/strong><\/td>\n<td>Drill, extension cord, laptop power adapter<\/td>\n<td>every 6 months to 24 months*<\/td>\n<\/tr>\n<tr>\n<td><strong>Fixed Installations<\/strong><\/td>\n<td>Permanently installed machines, distribution units<\/td>\n<td>every 4 years<\/td>\n<\/tr>\n<tr>\n<td><strong>Safety Measures \/ Ground-Fault Circuit Interrupters<\/strong><\/td>\n<td>RCDs in Non-Stationary Installations<\/td>\n<td>up to 6 months on weekdays<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/figure>\n<p>*Guideline value depending on operating conditions: In office environments, longer intervals are typical, while on construction sites, they are significantly shorter.
