The need to enclose wago connectors in a box

[ARCElectrical]

Hi all,
I am a BIG fan of the Wago connectors, but am I required to enclose them in a box? They seem to me, to be very well insulated in themselves....

The insulation isn't protected, hence the need for a box

 

[cdavies33]

Insulation tape??? LOOOOOOOOOOOL!!!

 

[ARCElectrical]

OK. If I understand you correctly, It is a requirement to make sure the coloured insulation is enclosed in the box?

Yes, the coloured bit is the insulation, the grey bit is the sheath. The cables themselves should also be clipped or clamped to ensure that no strain is put upon the terminations

You need the enclosure for mechanical protection, like cable sheath.

 

[ARCElectrical]

Are you telling me that the sheath of a 2.5mm T&E cable provides mechanical protection? Surely not..

In the regs it states that single insulated cables need mechanical protection. Enough said.

All views are my own, remember I'm just the apprentice

BS 7671:2008 Ammended to 2011 Reg:521.10.1 States Non-sheathed cables for fixed wiring shall be enclosed in conduit, ducting or trunking. This requirement does not apply to a protective conductor complying with Section 543.
Non-sheathed cables are permitted if the cable trunking system provides at least the degree of protection IPXXD or IP4X.

Seems very clear now, thanks micky86.

I can only conclude that the outer sheath of a 2.5mm csa T&E is considered to be a "Cable Trunking System" providing at least IPXXD or IP4X.

wx2 steel trunking buried in mrs jones's stting room walls, can you?ell, you can't have 2

Wago do boxes with inbuilt cable grips don't they?

You can use chocblox, wagobox or line enclosures. If you don't like any of those, use an adaptable box. Loads of ways to safely enclose a wago connector.

Edit... And yes, they must be enclosed somehow.

Yes. What else would it be for?

Are you telling me the name of your company is "Arce Electrical"?

Not the best mechanical protection, granted. Mechanical protection all the same....

No problem.... Now if only there was a thanks button..... Haha
