Hi I need to join two cables I’d like to do it under the floor so maintenance free would’ve best but I could do it in a conduit terminal box on the outside wall. What connectors would people recommend

    Presuming dry indoor conditions, then I would terminate the SWA In the usual way with a gland into a metal adaptable box. Short green/yellow fly lead from the gland. Joint phase, neutral, and earth with heavy duty through crimps and insulate with two layers of heat shrink.


    Note that to crimp joint larger conductors like this, you will need a heavy duty ratchet action crimp tool, NOT a cheapo "car boot sale" £5 crimper intended only for smaller conductors. (and of marginal reliability even for light duty use)


    I have been known to solder such joints, and insulate with self amalgamating tape, within a steel box. Soldering seems frowned on these days, but AFAIK is still permitted.


    If it might get wet, then a resin cast joint, these are available as complete kits.


    Seconded on the soldering. I have just replaced a 200 Amp three phase switched fuse with soldered lugs, initially installed in the early 60s. The lugs and connections were electrically and mechanically as good as new. They were retained and reused on the new fused switch.
