I am wiring a light up in the garage and adding a double socket and
have decided to use 20mm round conduit to house the cabling.

Does anyone have any tips on feeding the cable through the conduit ? I
am using inspection bends to make a couple of 90 degree turns and the
cable is getting stuck on the corners. Even with access to the corners
by removing the covers it still seems impossible to feed the cable.

I am using 2.5mm cable for the power socket. Can you use the cable
without it's external white rubber sheath when it is inside plastic
conduit ? This would obviously give a lot more room and make feeding a
single wire at a time easier. The PVC conduit itself must surely be
performing the same if not far better job than the white sheath.
