80% loading in Small power / Lighting Circuit breakers

Nick Parker
Is the 80% loading rule apply on lighting / socket outlet loads on a circuit breaker?, for example, if the circuit breaker rating is of 15A, the maximum load on that breaker would be 12A and you cant load more than that.

I think this rule is more common in Americas. How about this rule in Europe? Why 80% loading and not to the maximum capacity?

    There is no rule/law/Regulation with such a requirement in the UK.

    The UK even allow some controlled overload of circuits for short periods - cooker circuits for example, a cooker with a total loading of 40 amps can be fed from a 32 amp circuit breaker, as it is known that the 'overload' will only be for a short period, and irregularly.
