My ancient orange pyro that runs from a socket in my dining room to my shed has finally given up.
So I'm going to replace with SWA armoured cable , will 1.5 mm ( 16amps max) be enough , or should I go to 2.5mm (31amps max)?.
Also I guess i should fit an RCD indoors?
The old stuff is just a fused spur from socket.
Advice gratefully received ,thankyou............
Cable size depends on how big your shed is and what you do in it! If it's like a workshop then id lean towards 2.5mm.
Rcd is always a good idea tbh.
I used 6mm on the basis I will be using a welder and compressor etc. Then a small consumer unit with a main switch, a 32a and 6a MCB.
The garage runs off a 32a rcbo in the house.
Anyway, well worth getting bigger than what you anticipate needing, as the extra material cost is small compared tho the cost and grief of having to
do it again later.
Yes, definitely fit an RCD type device or maybe an rcbo which will offer overload protection too.
You say you are on a fused spur at the moment.
This has me thinking. Most of the above would mean changes to what you have inside the house. But no reason not to pur the bigger cable in, it will be
ready for when/if you have a rewire.
Besides, have you done the calcs for voltage drop? There is a handy tool for doing that on the TLC website...
I'm more intrigued by the pyro that has given up.....
We have pyro that was installed in 1959 and it's still sound. Even stuff that has been hammered flat still tests OK!

Just as disclaimer on the above, that I am not a qualified spark, and that the information has largely from information I had before hand or gathered
for and from doing my own garage, much of which came from the diynot forums.
It is my understanding that I was extending an existing circuit, that both ends of the swa terminate inside, and the garage is build from
non-flammable materials, none of the work I did was notifiable as under part-p of the domestic regs and hence should be done by any competent person
in which I include myself. Obviously it is up to you to understand what the situation is for your own installation.
