It is actually an inverter split type that I am having. But is is a 5kw, and
according the the installers it is a legal requirement for it to have its
own circuit with a 20amp trip, if it was a 3.3 kw, this would not be the
case. I do have a lot of equipment in my house running off the plug circuit
anyway.
The room where the air con will be installed is only 7ftx7ft, but a 5kw was
suggested as it is full or computers and associated equipment, plus it has a
south facing window. When I asked about overspeccing air conditioning units,
the reply was that with inverters that is not so much of a problem these
days.

Regarding andy's reply. I have not had any loop or drop calculation done,
nor have they been suggested yet. I would say that the original plan for the
cable route would be approximately 26 meters from the fuse box. When the
electrician comes to do the fuse box I am going to ask if it is feasible to
route it around the side of the house (outside), where there are cables
already, like TV and sky ones, at least part of the way. I would say that
run is about 15 meters. Is a loop and drop calculation a standard
electrician thing, is there any expensive or specialist equipment required?

Also does anyone know if I need planning pemission for a split type air con
unit?

Thanks,

James

Hi,

It might be worth paying more for an 'inverter' type split, these can
usually be run from a standard 13A socket and would save the wiring
hassle.

Can be cheaper to run as they adjust to the cooling load better, one
with a heat pump facility can take the chill off a room without
needing to run the CH.

cheers,
Pete.
