Leaving aside the downsides of Power Line Adapters, I do have a spare

I have power from the house to the shed on a B40 RCBO in the main fuse
board.

At the other end is the old (pre-rewire) fuse box.

Is there anything to be gained by sharing a fused spur with the RCBO
connection (that is, not relying on the PLA signal passing between
RCBOs)?

Just that I have the electrician in at the moment replacing green goo
wiring and this might be the time for a little extra work if there is a
major benefit.

FAR better to run cat5 to the shed.


This is the backup plan if the CAT5E fails to pull through the conduit.

Yes, Cat 5 is always the *best* solution, but it is often not the easiest,
as it involves drilling through walls (maybe masonry), routing the cable
alongside carpets (to make it as inconspicuous as possible) and under metal
strips in doorways, and maybe scrabbling around in a hot loft, perching on
beams and lifting the glass wool insulation. And there is always the problem
of how you feed a cable through a ceiling: you want to run the cable as
close to the wall, maybe in the corner between two walls, but you can't get
a drill right into the corner, either from below or from above.

In our new house, the wifi in the router was woefully inadequate. After
looking in the loft and finding very low rafters, and about 3 feet of glass
wool which made it precarious to move from one beam to the next (feel your
way gingerly to make sure your foot is on a beam!), I abandoned the idea of
running Cat 5. I could have drilled through the outside walls to run the
cable under the eaves, but that is a nasty job, especially as you need to
make all holes big enough to pass an RJ45 plug (I experimented once with a
crimping tool and found it impossible to get all the wires into the right
holes in the socket at the same time: I'd crimp and find that one of the
wires hadn't quite been caught by the IDC so I had to start all over again.
Anything smaller than a 3-pin mains plug is just too fiddly ;-) (is that a
sign of old age?)

I tried a Powerline device but even that didn't have a strong enough wifi to
cover all the house that wasn't covered by the router, and I discovered that
the range of the Powerline technology was so poor (intermittent dropouts and
generally very slow speed) that there was no point even thinking about
getting a second device to cover the wifi dead zone of the first device.

So I bit the bullet and bought mesh wifi devices (Linksys Velop) which are
brilliant, though the range of each one at 5 GHz (as used for the backhaul
connection back to the router) is not brilliant so we needed a lot more than
estimated for a typical house.
