Just finished a job by adding an fcu in an airing cupboard so a feed can be taken from there to run a whirlpool bath. Zs was fine and so was the trip times of the rcd protecting the ring that I took a spur from. My question is apart from the minor works for the fcu in the airing cupboard I took a cable from that to an IP 65 adadptable box positioned under the bath near the pump so I connected the pump to that.would I need a seperate cert for the adaptable box?
