Hi guys,

I'm re-wiring up my place, as part of renovations.
It was last wired about 50yrs ago, so needs it :-)
Anyway I'm putting in 1.5mm cable everywhere except
for the kitchen sockets (inc w.machine) where I'm using 2.5mm.
(I've a gas cooker)
I'm a bit concerned about the high current running through
this when for example kettle, and w.machine are on.
There will be about 4 junction boxes before the w.machine,
where the wire will be cut to allow a tap-off for a plug.
My concern is at these junction boxes, the cables are joined
using the common plastic, holder with screws (don't know the common name)
and this could be the bottle neck for the elctricial current,
potentially causing arcing, heat, fire..
Is this a legit concern ?
Should I run a separate cable to the w.machine ?

TIA,
Ray.
