Hope someone can help. At present I have a powered shed and a koi pond in the garden that are connected as follows
The shed runs off of a spur on the socket ring main and draws about 700W.
The power for the pond runs off of the cooker circuit which seems to be a radial circuit from the main consumer unit. I do not use this for the cooker and so only powers the pond. This circuit is connected via an armoured cable to a secondary consumer unit in a pump house and draws about 30A at full load (mostly due to a heater.) In effect, it has just extended the cooker radial circuit to a secondary consumer unit and the pond equipment runs off that.
I am however installing a new shed and a new cooker that will need the cooker circuit. I am therefore looking to rewire the garden. I am intending to run an independant armoured cable line from the consumer unit to feed the pond system and two sheds. My question therefore is :-
1. Do I need to run the dedicated armoured cable feed as a radial or ring main
2. Can one armoured cable feed into a secondary consumer unit that then split the power to the pond and the two sheds or should I run three circuits (either radial or ring) from the main consumer unit to the two sheds and the pond ?
Many thanks for any advice
