Im looking at having air conditioning installed in my kitchen/dining/living room after the recent long hot period.
I’m being offered a choice of 2 systems, either 7kw or 10kw. The 10kw system would suit the room size better, but the 7kw would be better than nothing.
To install, I have easy access to a power socket on the kitchen ring main. Or, reasonably easily, I can take a spur off the garage ring main. The garage ring also serves the bedroom above and has a 32A trip. The kitchen ring also serves the utility room, hall & study and also has a 32A trip. Obviously the garage ring is more lightly loaded than the kitchen one.
The 10kw air con unit has a max running current of 21A. The 7kw unit has a max running current of 17A.
The main distribution unit is in the middle of the house and the only way I can see getting a dedicated supply for either of the air con units would be to run surface mounted mini trunking round part of the hall & through the utility room (this may be necessary one day in the future if we need a charging point for an electric car, though this isn’t a current consideration).
So the question is, can either of the air con units be run off the existing ring mains?
