Crimp connections

[David.]

hey chaps,

do you need to put crimped connections covered with new heat shrink into an enclosure?? Connections are above a suspended ceiling and i know i could have got away with choc box etc as its accessible but i didnt

thanks

 

[ezzzekiel]

no there is no need

 

[High Tower]

I agree no its not in the regs, but i do, its just one of those things i like to do, for no other reason than my own personal satisfaction

 

[ezzzekiel]

i find due to the staggering of the joints that an enclosure is unsuitable

No mate diddnt mean enclosure, sorry i ment i heat shrink em just for my own satisfaction

I would do one or the other - either crimp and heat shrink, or in an enclosure using terminal or wago connectors.
Doing both seems like you're getting the worst of both.

Surley all electrical joints & connections need to go in a suitable enclosure.

crimped and heatshrunk is classed as permanent connection so no, the heatshrink replaces the insulation, nothing wrong either way, as hightower says one way or the other will suffice.

So should cables. As a general rule if the cables are suitably enclosed the crimps will be as well, often even without heat shrink.
I suppose the exception would be outdoors, in which case I'd use an IP rated enclosure, but probably with wagos or terminal connectors in it.

i have never been sure on the crimping situation, because the for example on t+e the grey sheath is your basic protection. if you crimp join does this not show insulation of the cores and therfore have no basic protection? i always crimp joints but have never done so outside of a enclosure etc, just wondered what you guys thought?

 

[Adam W]

Surely you mean 'mechanical protection' rather than 'basic protection'?
I reckon heatshrink would replace the mechanical protection of the outer sheath of the t&e.

yes i mean mechanical protection, as insulation is basic right? i get muddled with that, yeah i guess the heat shrink would, i never do crimps unless in an enclosure but just wondered.

 

[keniff]

or is basic barriers and enclosures.....

 

[Adam W]

Basic is protection under normal circumstances when all is well, so both insulation and barriers & enclosures.
Fault protection is protection under fault conditions, eg ADS or double insulation.
