    Why do MCB's buzz?

    A mate of mine has quite a few 12v low voltage down lighters installed on a 6 Amp MCB BS60898 Contactum brand. When he switches the load up IE he switches the dimmers of the lights to full power the MCB buzzes like mad, in fact the buzzing increases at the same rate as the power is increased...

    Can anyone tell me whether I can Use a 32A Type B Eton MCB in a Memera 2000 Consumer unit. I have a customer who has had an extension built needing 7 new socket outlets. I'm hoping to add a new ring circuit on a 32A breaker on the RCD protected side of his consumer unit by installing a longer...

    Megger MFT1502 blowing fuses and tripping MCB's

    I had this calibrated recently, yet every time I try a 'No trip' Zs test it either pops the neutral fuse in the leads, or trips the breaker. The only breakers that trip are the 6A breakers, the rest it will complete the test. Using the socket adapter also works fine. It does a Ze reading...

    D Type MCB's

    Can someone confirm please - I don't think this will make any difference but - would the replacement of a B Type breaker for a D Type have any effect on whether a compressor/motor start-up dimmed the lights in an installation? (assuming that both MCB's were able to cope with the current demands)...

    RCBO's replacing MCB's

    Hi guys, I am quite new to all this and I have a number of questions running through my head. One of them being..... Do most RCBO's fit into the space occupied by an MCB to enable that circuit to be RCD protected as I have seen posts to suggest this might be possible? (Of course this would be...

    time/current characteristics for mcb's

    Hi guys, this might seem a bit of a newbie question, but perhaps someone out there can put my mind at rest! Here goes; consider a 4mm t&e radial circuit as described in brb p363 being protected by a 32a mcb. Now, according to p282, assuming ref method c, the current carrying capacity of that...
