Crimping

[p11jor]

Does anyone out there prefer crimping to connector blocks? Over the last year or so I have found myself crimping at nearly every opportunity when fitting lights over using the connector blocks that are usually in the fitting, (providing there is enough slack cable for future change of fitting)

I dont know why this is but just seems alot more solid connection etc....

Anyone else find themselves doing alot of crimping?

I used to as I hate connector blocks, but wago/ helacon are my connector of choice

Either or mate...you use whats appropriate for the situation............

Bugger the OED has removed all references to criminal activity.

You’re a crimper, you freely admit to stealing the Queens coinage?

If your talking about using butt type crimps in light fittings, They are not really appropriate for this type of use are they!! In this case i cannot for the life of me, quite understand why you would even consider using crimped connections....

 

[GLENNSPARK]

Its called reinventing the wheel eng!!!...lol........

To stop anyone stealing the luminaires

As far as i can see, all this is going to achieve is p***ing off the next electrician that comes along that needs too test, disconnect these light fittings. Totally pointless exercise as far as i can see!!!

The problem with using crimps is they're a permanent joint, so to get them off you have to cut the wire - do that a few times and you're not going to have much wire left.
I think connector block has it's place, as do the lever action Wagos.

Exactly, he is converting purpose made disconnectable terminations, to permanent connections, and for no good reason!!! I wouldn't even use wago connectors in this situation, not when normal connector blocks are already in place, and 9 times out of 10 that connector block is a direct earth connection to the light fitting via a tab from from the frame into the connector block.....

Quite right eng...things are designed for a reason....if folk cant cope with doing things the recognised way (the way its been done for years) then they might as well throw away BS7671 and go it alone..........

id go connector personaly for the testin or altering angle

connector blocks are a good reliable connection, provided they are made properly. The correct by the book way, is to strip both connections to the full lenght of the brass block that is in the connector block. then insert. tighten both screws onto both conductors.
The common way but done professionally, is to strip both conductors to the same klength as above, but double them over, and tighten one screw onto each conductor. Doubling over ensures a better contact.

Had problems with insulated crimps on solid core conductors,they just dont bite. I've made what seems a perfectly good crimp,and yet after a few 'waggles'..(dressing back into the enclosure?)..the wires can be felt to have worked loose. Insulated crimps are fine on stranded conductors...but as already pointed out by others,NOT for a connection which may need to be disconnected in the future.

I only use crimps when extending cables. My pet hate is DIYers using the old brass blocks from the ceiling rose, with a bit of sellotape.


Best one is the permant live connected to the earth tab and the earths in a seperate block.
