Examples of constructions regarded as meeting the requirements include:
– close-fitting tubing (e.g. a heat shrink or synthetic rubber sleeve), applied over the wire and its termination;
- Conductors connected by soldering and held in place near to the termination, independently of the soldered connection;
– conductors connected by soldering and ″hooked in″ before soldering, provided that the hole through which the conductor is passed is not unduly large;
– conductors connected to screw terminals, with an additional fixing near to the terminal that clamps, in the case of stranded conductors, the insulation and not only the conductors;
– conductors connected to screw terminals and provided with terminators which are unlikely to become free (e.g. ring lugs crimped onto the conductors). The pivoting of such terminators is considered
