Can someone please explain to me the difference between an mcb, rcd and an rcbo and in wat circumstances is each used, I knw an mcb is your circuit breaker and rcd is a circuit breaker but wat u wud use in say a wet area but y is it better then an mcb is it a better disconnection time and iv been told an rcbo is an mcb n rcd all in one but to me I thought an rcd was a mcb with better disconnection time sorry if confused u I just not had it explained properly to me n told y u wud use 1 over an other thanx. MCB: A miniature circuit breaker is an automatically-operated electrical switch designed to protect an electrical circuit from damage caused by overload or short circuit. RDC: A residual-current device (RCD), similar to a Residual Current Circuit Breaker (RCCB), is an electrical wiring device that disconnects a circuit whenever it detects that the electric current is not balanced between the energized conductor and the return neutral conductor. Such an imbalance is sometimes caused by current leakage through the body of a person who is grounded and accidentally touching the energized part of the circuit. A lethal shock can result from these conditions. RCDs are designed to disconnect quickly enough to mitigate the harm caused by such shocks RCBO: An RCBO (residual current breaker with overload protection) is a device that is a combination of both of the above.
An MCB is used to protect the cable from damage due to overload and short-circuit currents by disconnecting the supply within a certain time. The time in which it disconnects the supply is dependent on the amount of current that is flowing. This is why we have maximum Zs values, so that in the event of a fault to earth, enough current will flow to operate the MCB within the specified time. (0.4 seconds for circuits ≤ 32A and 5 seconds for circuits >32A) ------------------------------------------------------------------------------------------------------------------- An RCD is used as additional protection against electric shock by detecting earth leakage (imbalance between line & neutral) but it will not detect a short-circuit between line & neutral. 17th Edition currently requires the use of RCDs for • socket outlets not exceeding 20A for use by ordinary persons except where the socket outlet is labelled for a particular item of equipment • mobile equipment with a current rating not exceeding 32A for use outdoors • all circuits installed in a Special Location • cables concealed in walls.

I popped into topps tiles to pick up a Rubi 40ltr tub bucket and free trowel for £12. I bought the bucket to make life easier cleaning as was told it’s pretty tough.
