Cable that looks like SWA but maybe isn't
I am trying to identify the cable that feeds our house consumer unit.
It was buried many years ago, before 1998 at least and quite likely
some years before that.
It's not a 'company' cable, the company fuse is outside, it used to
feed from an outdoor meter/company fuse, it now feeds (after a
re-route under the drive) from meter and company fuse in the garage.
It might be pre-metric SWA, the outside diameter is just over 23mm and
looks somewhat like black SWA. It's a three core cable with Red, Blue
and Yellow insulated cores.
I'd basically like to know what size it is if possible.
I'm not *absolutely* sure that it's armoured cable, was 'non armoured'
cable ever used?
