recording conductor sizes on schedules

psychicwarrior

Hello all 

what do ‘you’ record on EIC and/or EICR if a circuit has smaller conductor sizes downstream of its run (where origin fuse is adequately protecting)  ?

    Just worth noting. It would only be 5mm² equivalent at the equidistant point from the termination in the CSU. Each “arm” of the ring being equal resistance at that position. Anywhere else on the ring will carry current in proportion to the resistance of each “arm” following the usual formula for resistors in parallel. Conversely a radial circuit fed by two 2.5mm² cables in parallel is equivalent to 5mm² surface area as the two conductors are always of equal length.
