Joint between 16mm &1.5mm!

[rolyberkin]

A donut of a builder has helpfully run a piece of swa two core 16mm to a small feature fountain fitted with 1.5mm flex, suggestions on best way to join, couldn’t get the 16mm in a wago!

What is wrong with a bit of 60A terminal strip in a moulded box and a crimp on the flex.
Gland the SWA into the box and put the 16mm² in one side of the terminal block and the crimped flex in the other.

And you could place the ferruled end of the flex neatly in the strands of the 16, that would work and be cost effective.
Does it need fusing down or has it been done at the other end (upstream) of the 16mm?

Question.
Why did the builder put in 16mm in the first place?
Tell him to dig it up and put in the right size.

or

Tie the cores to a jcb and gently pull it. It will either stretch the 16mm's down to a usable csa, or pull the cores out from within the armour. If that works, then tie a flex onto the other end and pull it in as the 16 comes out.

I sincerely hope your reply was/is tongue in cheek shaun1.

It is for a pond pump, not a outdoor hot tub, with Pampas grass and saunas

Builder built the fountain and dug in the cable, customer had a load of 16mm 2 core left over from something else, they got their heads together and come up with what seemed like a plan!
Think will go with the connection strip or crimp ideas.

So do you condone that form of butchery then? Should have had the right sized cable installed in the first place, and not left it to a builder,who probably thought "got some 10mm in the shed, I know I'll use that"

Being fused down at the other end.

IP enclosure with suitable devices- Like a caravan hookup unit- fixed to the nearest wall or shed.

How about using a submarine joint like this , Resin Underground SWA Armoured Cable Joint Kit 1.5mm-16mm 2,3,4 core cable | eBay - https://www.ebay.co.uk/itm/Resin-Underground-SWA-Armoured-Cable-Joint-Kit-1-5mm-16mm-2-3-4-core-cable-/263575621918?redirect=mobile

63a rotary isolator or a 63 interlocked socket with the pond flex on a 63a plug
Then it’s also got a local isolation point for maintaince

I've been looking in my recycling bag and have found some old CU brass connection blocks, I am thinking judicious use of an angle grinder and some heat shrink all housed in a wiska box and Bob's your uncle.......!

 

[Devonchris]

If the size of the conductor is going to be reduced from 16mm to 1.5mm then, leaving aside the IPxx rating, and providing its all tidy and insulated, could someone please explain why the suggestion of using a single strand into a wago would be frowned upon. To me it seems a practical way to reduce the conductor. What am i missing?

Well we are where we are with things here. Can't see its going to cause probs for this particular example? Have you never gone to bed at night, and not brushed your teeth.

At least volt drop won't be an issue!! Lol
