    TN-CS main bonding cable typical leakage current question.

    OK I'm prepared for the usual onslaught so here goes... I recently bought a clamp meter Uni-T UT210E. The first thing I did was check it out against my trusted AVOs and also a couple of other cheapo DMM's, (measure current through wire through probes and compare to clamp reading). The clamp is...

    Residual Current v Earth Leakage

    I think I must be missing the blindingly obvious, but..... TT system......100ma time delayed as main switch, then some final circuits (which will require 30ma RCD as includes sockets etc)...then 30ma RCD for other final circuits... Prior to changing CU at customer's request to include 100ma...
