Hi All,

Thanks very much for your replies. Some responses to your
questions...

Wago connectors look perfect. I have never used them before but they
look brilliant thanks.

Double checked the outer diameter of the cable and it is definitely
20mmish (probably 21/22). The feed was always planned to go out to an
outside kitchen area so I recall it being over spec'd just in case.
If the core is so big I may end up having trouble getting the 2.5mm
in the fitting too!!!!


If you look at:

http://wiki.diyfaq.org.uk/index.php/..._Wire_Armoured

That has the diameters for various SWA sizes shown. So it suggests it
could be a very substantial sized cable!

You may find it easier to terminate that in a junction box first and
come down to a more workable cable size.

It looks like the original plan was ok except for the current debate
about whether the lighting circuit requires a separate fuse or not.
If it ends up that it does require a fused is it possible to buy an
outdoor fuse?

At the risk of offending a pro in this field, I'd expect a cable this size
to terminate in a small CU. Then you can arrange power and lighting on
separate sub-circuits.

Yup often that size cable would be a sub main feeding a CU or similar.
In this case it sounds like its just a bit over provisioned for a single
socket circuit. Nothing wrong with that as such, but it does make it
harder to work with. Terminating in a small CU would be fine, if you had
a building in which to locate it, and a need for a number of separately
protected circuits.
