Loop and RCD testers can work in tandem, with an RCD (Residual Current Device) capable of breaking an electrical circuit before it causes harm, whereas a Loop Tester is a quick, convenient and highly specific method of evaluating an electrical circuit for its ability to engage protective devices (circuit breakers, fuses, Ground-fault circuit interrupter).Loop testers and RCD testers are critical tools for professionals in the electrical industry, enabling them to assess the safety, compliance, and performance of electrical circuits and protective devices. By utilising these testers, electricians, electrical engineers, safety inspectors, facility managers, and maintenance technicians can ensure electrical systems are operating safely and within regulatory standards

### What are the functions of Loop Tester?

The primary reason for earth loop impedance testing is to verify that if a fault occurs in an electrical installation, sufficient current will flow to operate the fuse or circuit breaker protecting the faulty circuit within a predetermined time. The aim is to make sure that the circuit is disconnected fast enough to prevent overheating and possibly a fire.

### What are the functions of a RCD Tester?

With a single-phase circuit, the device monitors the difference in currents between the line and neutral conductors. This life-saving device, designed to prevent you from getting a fatal electric shock if you touch something live, (e.g. bare wire), offers a level of personal protection that ordinary fuses and circuit-breakers cannot provide.RCD is a generic term applied to a family of products which open automatically in response to a residual current equal to or greater than the RCD's rated residual operating current.An RCCB differs from an RCBO in that the RCBO will additionally respond to over current conditions whereas the RCCB will not respond to such conditions. The term SRCD applies to an RCD which is an integral part of a socket outlet or which is fitted in a box immediately next to a socket outlet.
