I know that if an electrical connection is to be plastered over it must be
crimped or soldered.

Could someone please provide a link to a suitable joining piece (either
crimp or solder).

My screwfix catalogue seems to only show standard crimp connections.

Any advice on regulations regarding this type of joint would also be
helpful.

Thanks
Steve.


I don't actually understand your posting. Screwfix -other suppliers are
available- supply Crimps AWG 22-18, 16-14, 12-10 (insulated terminal) and
mm² 0.5-1, 1.5-2.5, 4-6 (insulated terminal). these crimps _must_ be
'crimped' using a specified crimping (distorting) force to assure
connectivity - this is achieved by utilising a ratchet action cramping tool:
see;- http://www.screwfix.com/app/sfd/cat/pro.jsp?id=70036&ts=02860

OK thanks for that.

Apart from the specified clamping force, these just look like the
standard crimps that I have been using for years for bodges on old cars.

Once the connection is crimped, and presumably, insulated with heat
shrink tubing, is there anything to do other than plaster over?

Does the joint need mechanical protection i.e. a metal box with a cover
before plastering? Or is the plastering deemed to be enough?

How about the soldering option. Is a suitably twisted pair of wires, to
ensure mechanical strength, then soldered and insulated as above OK?

Sorry, too many questions!
