Over current is the current that exceeds the design current, so on a radial circuit supplying a fixed appliance such as a shower should never exist, because no diversity is allowed in the circuit design unlike a cooker circuit. Over current on a shower circuit including the MCB is not permissible it is a design failure.
The circuit is the complete assembly including the circuit protective device, so a MCB supplying shower must never be overloaded, even if it is not an immediate danger.
You cannot treat every circuit as a socket circuit and assume that unknown loads will be connected resulting in an overload and say it will be all because the MCB will trip, neither can you under specify the circuit, which includes the MCB, in the first place.
