Hi everyone, I've added a junction box to an SWA cable in my garden to allow me to make a 3 way connection (I will fit an outside plug at later stage). I've fitted SWA glands, but I'm not sure how to join the cores inside the box! They're thicker than I'm used to. Should I use connectors (3 way)? If so, should they be 32 amp connectors? The breaker for this dedicated circuit is 32 amps. Why I'm partly confused is the previous house owners used 30 amp connectors on this circuit.
Also, the cores inside the cable are brown, black and grey. Am I correct that black should be earth and grey should be neutral (sleeved G&Y and blue respectively)?
I've reached out to the electrician I normally use, but he's on leave. I'm keen to finalise asap so I can concrete over the burried cable.
Thanks very much in advance for any help. Best wishes, Tim
