Your best bet is to buy a smaller motor.

The issue isnt so much with the 16/32A fuse rating. It's largely down to the size of the supply into the house, cable diameters and volt drop.

If you try and run a huge load of a small cable, the volt drop will be higher, and this in turn increases current draw. And motors starting up draw a lot of current unless there is an inverter or other similar soft start control.

Even a 3HP motor off a 13A outlet, either plug/spur or direct connection will still blow the fuse on startup quite often unless it has a good power supply ( ie cable size ), and if it does survive, the actual switch or plug will melt over time.

You could have what is called a 32A supply from a 2.5 ring....but what feeds the garage ? What cable diameter etc ? How long ? Plus What supplies the house ? Cable diameter etc.
Having a large diameter at the end of a circuit is pointless if it has a long and tiny cable feeding the start.

For any normal domestic household on single phase, 3HP is the absolute max you should consider, and you need a good sized supply conductor direct from source to the power outlet for the motor.
I didnt say cable direct...as naturally it may involve an additional consumer unit etc. But conductor size needs to remain IMO capable of 63A or more until the final dedicated circuit to the compressor. Which even for 3HP, needs to be at least 4mm^2, or better 6mm^2 and a 16A blue 3 pin plug or direct on/off isolator

Even then, when the motor kicks in, lights in the house can likely flicker, and some fluorescent style lighting can knock off and restart.


Another option which will help, is if you can get a soft start setup for it. This will reduce current draw on startup. Although actual running current can still be high.
Ive googled and there are some available, although Ive never used one myself.

Something like this, no idea on cost though. You'd need to speak to someone with more experience though to check actual suitability
