# Isolator for self-consumption
If you have recently installed solar panels in your home or company, your distributor may have sent you a notification that basically tells you that if you want to register the photovoltaic self-consumption installation, you must install "a cut-off element in the generation derivation next to the meter".
In other words, next to the generation or border metering equipment (depending on the type of configuration), but always within the same CPM, you must install and legalise a disconnector or cut-off switch that allows the operator to manually interrupt the flow of energy between the home and the external meter, ensuring that there will be no current when working on the meter.
This is a requirement that the distributor will demand all self-consumption installations, regardless of whether they need to open a dossier or whether it is not necessary based on current regulations.
"A general cut-off element that provides isolation for the protection of the health and safety of workers against electrical risk (...) The functions of the general cut-off element may, if necessary, be covered by another device of the generating installation, which provides the indicated isolation between the generator and the grid".
**Article 14. Protections, of this RD (1699/2011).**
