[QUOTE="Traineeboy, post: 519734, member: 32807"] I understand that for a TN system it is 0.4 max disconnection time. If for a distribution circuit you are allowed 5s max disconnection time, does that mean if you have a garage consumer unit on a MCB of the house consumer unit does that make the circuit a distribution circuit serving the garage and therefore the disconnection time is 5s ? Or have I got that wrong ? [/QUOTE]
