I need to upgrade my meter tails to 25mm. The existing tails pass along under the pebble dash in plastic conduit (which would be too small), then apparently at an angle through the porch structure (unprotected) then turn sideways into a void & up the void to CU.
I have seen other posts where the use of SWA is suggested but I haven't actually seen SWA with 25mm cores. "25mm SWA" appears to be 25mm "Outside diameter", so I presume that means the cores are smaller.
Any suggestions as to the best approach welcomed. I actually think I will struggle with getting SWA through anyway even if it does exist with suitable cores, because of the bends involved.
NB The meter box is under the window of the house rather than on the side of the porch, but the void inside the porch is set back behind the run of the outside wall so it's not possible to drill directly through the outside porch wall into it.
