How to set up a Megger 1741 MFT to test AC RCD’s, A Type RCD’s and B Type RCD’s With Lee Baker

[@marcusbarritt91]

Hi guys, Gaz is aware of the auto correct mistake of Megger at the start of the video, he sends his apologies 😁

[@GSHElectrical]

Thanks Marcus 👍... apologies all round

[@lsnogaming2893]

Gary is fully aware of the auto correct spelling of MEGGER in the title. Great video as always lads 👍

[@alextaramsari]

This Marcus guy is something! Thank you all.

Great video. I'd love to pick Lee's brain on the mft the knowledge the man has is unreal.

Another well presented and informative vlog guys, keep them coming

[@GSHElectrical]

Thanks Mike. Don’t know how much longer I can keep producing three videos a week every week 52 weeks of the year. 😀👍

Great video, great instrument 👍

[@duckman5642]

All very good, can we have 2 green and 1 red LED type lights on the display to verify p-e, p-n, polarity for easier verification at a distance like on the Kewtech KT42 loop tester. That would be a great improvement. Thankyou

Great video team 🤗🤗🤗

Works on the Mft1731 as well, not sure what extra features the 1741 has over the 1731. Nice video I hadn't noticed that feature

Paul Tipton thanks 👍

So when on type A setting in auto RCD test mode, does the MFT do twice as many tests as in AC mode? How else would the MFT verify that the RCD trips on both pulsating DC and AC earth faults?

[@GSHElectrical]

If you do the auto test on AC and the A type RCD setting you have covered all tests on an A type RCD 👍 (10 tests)

How do you test an mccb with mft1741

[@kendoknackersackee]

The move toward type A & B RCDs begs the questions: what type of residual current protection is being offered on RCBOs? How many different combinations of protection will there have to be on various RCBOs when factoring in the types B & C overcurrent protection with the AC, A & B earth fault protection? 😵

[@GSHElectrical]

Hi. RCBO’s are generally A Type. Have a look on my Instagram page for information GSH_Electrical 👍. Thanks Gaz

[@kendoknackersackee]

@@GSHElectrical will do. Thanks Gaz👍

[@izmirhoxhaj5896]

My Megger is count 30 seconds before tripping the RCD and it only give 130 ms for every rcbo , has this happened to anyone?

[@ashmanelectricalservices4318]

I would say the auto start RCD function is best for use where using the 3 test probes and pressing the start button could prove difficult, for example at a ceiling pendant or on a floating connection of a decorative light. Or you could just do it at the consumer unit 😉 kzbin.info/www/bejne/aYW0p6uHlKx5ZsU

[@GSHElectrical]

Great shout Alvin.... I do love my 3 lead tests 😂.

[@icanrememberthis]

Interesting, we are permitted from using type ac all together for domestic dwellings.

[@GSHElectrical]

Hi. Very limited applications now in domestic installations. All the best Gaz 👍
