    t&e and singles

    Is there anything wrong with having t&e mixed with singles on a ring circuit? For example a kitchen ring with conduit linking everything. The 2 legs coming from the garage would be t&e as they will be clipped to joists. But as everything in the kitchen will be conduit it would be easier to pull...

    Identifying csa of t&e

    Greetings. I tested an rfc and recorded the following results: r1 = 0.62 rN = 0.89 r2 = 1.45 The difference in r1 and rN indicate loose connections so I checked all the sockets (bar one) on the ring which revealed two loose connections. The rfc now tests as follows: r1 = 0.58 rN = 0.59 r2 = 1.45...

    sizing containment for T&E

    Does anyone have experience sizing cable tray/ basket and trunking which is used for twin and earth cabling? The on site guide only provides guidance and factors where single core PVC cables are used. I am looking for help where twin and earth is used.

    Volt drop tables for LSF T&E

    Which table do you use in BS7671 for volt drop for LSF Twin and Earth? There does not appear to be a table for LSF cable. 4D5 refers to the grey PVC cable and is not the right one to use for the white LSF. Any help would be appreciated.
