Discuss Crimping of flexible conductors in the Electrical Wiring, Theories and Regulations area at ElectriciansForums.net
if your using very fine wire, im thinking tri-rated not 6491b btw.I've just been reading the IET requirements for electrical installations 17th edition.
526.9.1 states "in order to avoid inappropriate seperation or spreading of individual wires of multi wire, fine wire or very fine wire conductors, suitable terminals shall be used or the conductor ends should be suitably treated."
526.9.2 states "soldering (tinning) of the whole conductor end of multi wire, fine wire and very fine wire conductors is not permitted if screw terminals are used. "
I've always twisted and doubled over; C&G 2365 say this is okay. But you must be careful of not over tightening in case you damage the fine wires. Although the more I think about it I will probably treat myself to some quality Hez crimpers.
So we know we can use "suitable terminals", (assume crimping), but can't tin; so otherwise what else is "suitably treated" ?
