70mm to 35mm joint

[daveb1]

Hi

Half due to me slightly over sizing a cable and the terminals of the MCB being far to small, looks like i need to join 70mm and 35mm conductors together, its underneath a cooking suite in a large commercial kitchen, there will not be a great deal of space to work.
i would like to use a straight through crimp then heat shrink BUT is there some kind of reducer i can use?

Would bolting lug crimps together be a complete lash up?

Any constructive help would be appreciated

Thanks Dave

have a look at these, don't know if they will be any good in your situation for the terminals.

What type of cables are they?

Yes it would.

its a 4 core swa 70mm and the MCB i thought the only option would be connect to 35mm to fit into MCB terminals

The one at the top of the page , is the type we use along with a length of suitably sized heat shrink .
They are near on foolproof , as the bolts will shear as they reach a predetermined torque .

Use pin lugs as linked to above to connect the 70mm to the mcb terminals.

These are the 50mm - 240mm versions .

Thanks guys due to the restricted space to terminate above the mcb i think the SWA mechanical joints look like there perfect job

We use LML for lugs etc, based in Calne, Wiltshire.
these are what you need..... http://lml.shopwired.co.uk/specs/1579367.pdf

you specify the sizes of cables you want to join and they'll supply them.s
