Rated 5 out of 5 by Good mcb Good price. Works as it should. What else is there to say it's an mcb. 15 May 2015
Rated 5 out of 5 by Testing As an MCB is part of the circuit protected by the RCD, when you test the RCD by carrying out the test at the end of the circuit at 1/2i, i0 deg' , i180 deg', 5i 0 deg', 5i 180 deg', Ramp, Loop and PFC, you also test the MCB at each of these tests. I have used BG mcb's for several years and have found them completely reliable I have never had a new one fail during testing. I have had a couple of RCD's fail but I always carry spares and Screwfix have always exchanged the faulty RCDs without question. 3 stars for features because there are no "features". These MCB's are the equivalent of other makes but better value. 30 Apr 2015
Rated 4 out of 5 by Great Product Use BG all the time and have never had a problem. Great product. 11 Oct 2014
Rated 4 out of 5 by cheap, not the most reliable I like the BG consumer units, they're good value, nicely built and come with built in spirit level. I have however had a couple of the MCBs fail on me during installation or shortly after so make sure you have spares 27 Sep 2013
