Outdoor socket - daisy chain to shed - ok to do?

[paulfoel]

Previously I had a kit. RCD inside to outdoor socket then armoured cable out the bottom of this to shed to another outdoor socket.

Not the best quality and the shed one I replaced years ago with a better one.

The first one in the chain needs doing now. Will there be anything special about this socket, which previously allowed me to feed to next socket, or can I just double up the connections and wire out the bottom to far end socket?

Is there a fused switch inside, feeding this first outside socket?
Is the circuit that feeds this already RCD protected, perhaps in the consumer unit?

RCD plug in socket inside the house, which feeds into this.
