Live line work (LLW) is defined as work on live parts of electrical systems or equipment. This only applies to dangerous touch voltages, i.e. not to the 12 V system.
The most important rule for live line work is: don’t do it if you can avoid it. But reality shows; it cannot always be avoided. You cannot switch off a photovoltaic system, as soon as the sun shines on PV modules, these PV modules supply voltage.
The prerequisite that electrical specialists must fulfill in order to carry out LLW according to § 8 DGUV regulation 3 is, in addition to the technical knowledge and personal suitability, the qualification according to DGUV regulation 103-011. This comprises a theoretical and a practical part including an examination.
We will gladly qualify your employees in-house for live line work in our photovoltaic training LLW-PV and also advise you on the in-house framework; the use of your own employees is also linked to further organizational measures. Our goal is to ensure that you and your employees work safely and legally on PV systems – when live line work is necessary.
