Earthed selv circuit
WebMar 1, 2024 · For domestic applications, SELV and PELV transformers will have a 230 volt input and an output in the ELV range, so anything up to 50 volts A.C. or up to 120 volts D.C. Typical output voltages are 5 volts for telephone charging, 11.5 volts for lighting etc. WebA SELV circuit must have: protective-separation (i.e., double insulation, reinforced insulation or protective screening) from all circuits that might carry higher voltages Simple separation from other SELV systems, from PELV systems and from earth (ground). No live conductor at SELV must be connected to earth
