    UK MCB's vs Cartridge fuses

    Hi all, need to pick the collective brains as im concerned about a recent problem. We have a few freezers here on our small holding and one of them started playing silly buggers. Eventually the 20A MCB kept tripping so to make sure it was the freezer i put it on a different circuit with a 16A...

    Which is better BS1361 or BS88?

    Was wondering why was BS1361 replaced by BS88 even though BS1361 tends to have a larger breaking capacity according to the on-site guide if I'm reading it right, however, I maybe wrong.

    Why do we use cartridge fuses and not MCBs?

    A customer asked me this today and I couldn't answer. Why, in LARGE switched fuses (60-100amp) do manufacturers use cartridge fuses and not MCBs?

    13 amp cartridge fuse.

    Just how much current can a 13 amp fuse potentially (no pun intended) pass? I've seen loads plugged into fused multi-ways in excess of 3120 watts and wondered if anyone had ever tested this. New here so sorry if this has been asked to death!:waving:

    Old Wylex Cartridge Fuse for Light AND Power = 45Amp

    Ok, my flat was built in about 1960, it has a very old wylex fuse box for which the fuse for the heating and power is one switch. The lights have blown but I still have power. In the past when the fuse has blown the power and lighting has been lost so therefore the fuse has not blown this...

I went round and tested the circuit and found...

    Hello guys this is my first post as I'm only recently qualified (but doing the job for 4 years) . But my question is as my title suggests. Is it acceptable to add 80A 30mA incoming RCD before a cartridge fuse board but the wiring is still in compliance (pvc/pvc, csa's etc). They don't want to...
