As well as providing all of the facilities needed for testing low-voltage single-phase installations in line with the IET Wiring Regulations, this innovative instrument can also check phase sequence, evaluate prospective short-circuit current up to 20 kA, perform phase-to-phase loop testing at 415 V, and test three-phase RCDs even when no neutral connection is available.

Additionally, the Megger MFT1721, which is one of the new models in Megger’s popular and successful MFT1700 range, offers valuable extra features, including: true RMS voltage measurement, facilities for testing the Type B RCDs and a millivolt sensor input. It also features fast-response continuity testing at 200 mA or 15 mA and, with an optional current clamp accessory, it can be used to measure current.

Like all instruments in the new MFT1701 range, the MFT1721 provides three options for loop testing – two-wire no trip, three-wire no trip and high current – which means that the fastest and most convenient method can be used in every situation.
