not exactly a bs rated joint boxWhat about being in trunking (as in the metal 4x4 stuff) That must count as mechanical protection to be sure !
eh???the connections you r talking about these r the new ones that come in different colours
reg526.3(iv)says he's right .still needs to be in a joint box
not exactly a bs rated joint box
c'mon Wayne, thats not what 526.5 says.......
no, Wayne, trunking isnt a BS rated joint box, but the regs doesnt call for a BS rated joint box does it!
Because solid core breaks under vibration at weak point on crimp, because of expansion and contraction eventually losens the joint, stranded does not
If working for the water board, power stations large steel works, mines and quarries etc, anywhere in fact with a clerk of works and a spec. Solid core cannot be crimped. I know because once we had to rip about 1000 metres of 1.5 7core out, because it was solid core and all connections out in the field were crimp connections. And thinking about other places I've worked never have crimped solid core before.
We didn't know it was solid core until connection time, nor did the gaffer, tried to bluff through..no chance it was spotted quickly. Wholesaler at fault, or so was told to us -;
At the time I wondered why not, ask the clerk of works...he looks at me like mainwaring looks at pike..Because solid core breaks under vibration at weak point on crimp, because of expansion and contraction eventually losens the joint, stranded does not..and your boss should know why...oops
So, and sorry because this is probably off the topic now, if you want to join say a 2.5, can you use spring loaded multiconnectors like Helacon Plus range - in a box, which can then be inaccessible?
However I like crimping, its therapeutic.
As long as the crimp is attatched using the correct tool then there isnt a problem ,correct tool i mean ,a ratchet crimper not a hand crimper , yes it does crush the solid core but so does every termination you do ,how often have you fixed say a light switch and over tightend it and the wires broke ,so crimp insulate job done ,great for mains board upgrades when the wires need extending
Only cable that shouldnt be crimped is cable with aluminium conductors ,as for insulation over the joint i use 8kv rated coloured self amalgamating tape
