You've used a black as a neutral, and the grey "neutral" as earth. If you're going to bodge it then bodge it properly and get a plastic stuffing gland for the T&E and a Wiska box that will at least be water tight and re-terminate the armoured correctly and with some earth sleeving and neutral blue sleeving at both ends.

What's the Zs at the Garage mate?

Can't really see him knowing that, not many DIY'ers have a loop tester or MFT.
 
Hello all,

Got a bit of a situation with my new garage, I've got a 2.5mm cable coming out of the house consumer unit for supplying mains to the garage, there is an armoured cable inside a conduit that goes underground and comes out in the garage. Inside the garage, it goes into its own consumer unit and the rest is good.

The problem I have is the junction outside the house where the 2.5mm meets the armoured cable, I can't find any glands or outdoor rated junction boxes to suit an armoured cable and 2.5mm.

This is how it looks at the moment, not ideal but stays dry with the lid on and I keep the supply off when not in use. It's a random metal box, not suited for this purpose, it has holes in it and doesn't have any ingress ratings.

Please can someone recommend a junction box to suit both the armoured cable and 2.5mm or similar solution? Thanks!

Lolopopo You will need one of these: 32 Amp Wiska Junction Box 85 x 85 x 51mm - Black IP66 - https://www.tlc-direct.co.uk/Products/WK308B.html?ad_position=1o2&source=adwords&ad_id=45425533757&placement=&kw=&network=g&matchtype=&ad_type=pla&product_id=WK308B&product_partition_id=174057601027&test=finalurl_v2&gclid=CL6wzOOt2dQCFa637QoduDEElQ
And for earth continuity on the armoured cable one of these: Wiska Earth Clamp Bar for SWA Glands - https://www.tlc-direct.co.uk/Products/WKEC308.html
An SWA gland CW 20mm Small Gland Pack - 3 Part External - https://www.tlc-direct.co.uk/Products/TLC20S.html
And for the 2.5 twin/cpc cable: 20mm Nylon Compression Gland Black for Cable 7-10mm² - https://www.tlc-direct.co.uk/Products/EK251B.html

Firstly, using a spanner screw the swa gland through two of the seals adjacent to each other on the box to 'break through' these seals. Then remove and fit the swa gland to armoured cable first, then screw the box onto this, then fit the earth clamp inside the box. Make a lead to connect the earth from this clamp to the earth connection inside the box. Fix box to wall in a way which will leave both cables exiting from the underside. Now screw in the plastic cable gland and fit the 2.5 twin/earth cable. Although some will slate you for using the black as neutral and grey as earth, it really makes no difference as long as they are taped or sleeved in some way to indicate their use. However, it's very important to check how they've been used at the garage end of the armoured cable and replicate this. Let us know how you get on, and maybe post a picture of the finished job so that someone can point out any potential problems before you re-energise the circuit. :)

Not a hanging offence. I think it's only the NIC that mandate using the black core for the cpc. Nothing in the regs for single phase circuits using brown/black/grey cable for L, N & E, unless you know different. (Yes I know the sequence for three phase is defined.)
 
I guess not but it should be sleeved at the very least?
Appendix 7 2
2.1 Single Phase
An addition or an alteration made to a single phase installation need not be marked at the interface provided that:
1 old cables are correctly identified by the colours red for line and black for neutral and 2 the new cables are correctly identified by colours brown for line and blue for neutral

Oh yes, quite agree about the sleeving.
