Got it confirmed that it's a similar model to those I listed but couldn't
find it on the Mitsubishi website. This is the beast.
I may well stick a separate feed in for it.
Thanks for the advice everyone.
Fuse Rating (BS88) - HRC (A) 16
Starting Current (A) 27
Running Current (A) - Heating / Cooling 4.34 / 4.65
There's another 40W for the indoor unit, but I think that can be ignored...
Starting current is very believable for an induction motor compressor.
If mine tries to start with a locked rotor (as happens with compressors
if they try starting too soon after they switched off and there's still
a pressure differnce across them), it draws over 4kW (limit of my power
meter), but not for long enough to blow the 13A fuse before it realises,
and then it waits a bit before trying again.

The starting current figure isn't always shown on the specs I've found - but
where it is, there is further evidence to support the 27A startup figure
(much lower figure given by my air-con fitter over the phone) so looks like
you're right Andrew.
The breaker currently fitted is a type B 16A and my understanding is that
shouldn't trip with this sort of startup current (earlier thread suggested a
type C may be needed). Any thoughts/experiences on that?
Out of curiosity, how does the startup current on a motor stack up against
the rating of the cable? I think my single 2.5mm has a rating of 27A anyway
(clipped, not in conduit) so isn't a problem - but what sort of peak current
can a cable take above its continuous rating?
