B1

Maximum route lengths for conductor sizes and protective devices

The maximum circuit length tool reads the route length Table B1 allows for a conductor pair and a protective device, for a 0.4 s disconnection time at 230 V. A pair the table does not print has no tabulated length.

Na-verify: binasa laban sa naka-print na standard, mga pahina 452–453. Na-check noong 26 Sept 2026.

Mga unit: Active mm², Earth mm², Rating A A, Type B m, Type C m, Type D m, Fuse m

Ito ang mga value na ine-encode ng AmpSize. Walang text ng standard na inilalathala. I-verify laban sa kasalukuyang standard.
