The Megger MSA1363 socket adaptor enables connection of electrical test instruments to the line, neutral and earth of a circuit using a standard socket. This removes the need for the user to dismantle any socket or having to expose any live connections or terminals. The tester allows for R1 and R2 measurements as well as voltage detection, with a CATII 300V safety rating. With its colour coded front mounted sockets, the MSA1363 enables test leads or equipment to be connected accurately and safely. Using the MSA1363 reduces the risk of damaging the socket or surrounding areas, allowing measurements to be taken using the supplied standard 4mm connectors.
