Good mcb Good price. Works as it should. What else is there to say it's an mcb. 15 May 2015
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
Great Product Use BG all the time and have never had a problem. Great product. 11 Oct 2014
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
