Ethos 7800 Loop/RCD Tester Combined
Suitable for Part P and Approved Certifiers
The Ethos 7800 is a combined earth loop impedance/ RCD tester for testing of energised circuits. Utilising the latest technology, the non trip loop test allows a safe test result even if an RCD is in circuit and gives an accurate value to a resolution of 0.1½. The RCD test has an auto sequence facility allowing the contractor to stay with the RCD and keep resetting the RCD until it stops tripping. It saves time on testing but also ensures the correct procedure has been carried out simply and safely.
