Ferrules and T and E

[brizospark]

Would it be considered bad practice to ferrule Twin and earth conductors?

 

[truckster]

Why would you want to?

 

[Bright Sparks]

You can, lots of lighting manufacturers do, you are not allowed is to 'Tin' them with solder, but as Truckster says, why would you want to????

 

[Knobhead]

I’m confused……. Why use ferules?

Why can’t you tin a conductor?

 

[brizospark]

well it has been specified in contract that final connections to DBs are to be ferrulled but I too am thinking why would you want to

 

[plugsandsparks]

I can understand it if its all trunking and singles but solid cores ?.... never tried it, doesn't make much sense really

I don't mind ferruling connections in panels, but i hate double bootlace crimps! They make it a ball ache to fault find ect! I prefer RYB crimps. I wouldn't ferrule solid core cables. The only reason bootlace ferrules are used is to stop the cable from flattening excessively during termination, and to keep the strands together.

 

[Engineer54]

Why not?? If it's specified in your companies contract, that's what is installed!!

We have the same specification on our project. I find you get a better/tighter connection at the MCB terminals, probably because of the greater CSA you get, using a ferrule crimp!!! Certainly aesthetically looks a far better finished job!! lol!!

 

[brizospark]

Would agree with you engineer54, aesthetically it looks more professional and I think a better connection is acheived with the ferulling of the cable

 

[brizospark]

I will also add that when ferrules are used at a DB it makes identifying the CSA of the cable far easier when carrying out a periodic etc

 

[benji]

are we confusing ferrules ie cable markers with bootlace crimps

 

[brizospark]

RS would say differently they class as 'ferrule' and what's cable markers gotta do with the price of ferrules?!!!

I like to fit cord end ferrules to 6mm and 10mm t&e when putting in showers etc. It stops the strands spreading under the screws and imo produces a better joint. Burned out connections are a common problem at this cable size and so far non of mine have had this problem.

Always fit cef's to flex in all applications (usually uninsulated ones).

I still don't get it.
OK you might use ferrules on stranded, and especially fine stranded cable to keep the strands together and give the conductor the properties of a solid core cable, so why would you need to give a solid core the properties of a solid core? It seems a bit like running SWA in trunking.
