Ask yourself, "Why do I need all this compressed air when I don't have any at the moment ?"

The standard 3 pin UK plug is rated at 13A, so about 3kW at 230V. As part of my 3-phase installation I have a single phase 32A outlet; that can supply 7.36kW. It is possible to get 63A outlets which, at 14.5kW, might just run the compressor.

It could be tricky running a 63A outlet from a standard consumer unit; my 32A outlet comes from a 3-phase distribution box. In general the highest power circuits in a domestic environment are 45A for cookers and electric showers.

So, in theory, it might just be possible to run the compressor on a single phase supply, although how the incoming supply and consumer unit would stand up to it is another matter. It is possible to run a 3-phase motor on a single phase supply via a static converter, but when running the motor only produces about half nominal power, as one phase is essentially unpowered. That may be a problem with a compressor.

As a matter of idle curiosity I wonder how the OP is going to judge whether the responders know what they're talking about or not?

To clear up a couple of points. The main overcurrent protective device, (main fuse) for domestic installations supplied in particular on P M E has a value of 100 Amperes, as per the suppliers requirements. If a smaller capacity fuse is fitted it will be for a reason specific to the installation. The motor in question on this thread cannot be wired for Star or Delta. The plate clearly states the CONN, (connection) is Delta. The voltage rating backs this up by stating the voltage requirement to be 380 /420 v. The Amperage at 28.6 and 25.8 in relation to these voltages gives further weight as does the Service Factor and the Service Factor Current draw relating to the voltages, They are the between phase voltages for a Delta connected motor. Now, I would like to learn something here. I know that 3 phase machines can be run by various means from a single phase and if I'm reading the O P correctly it was stated that a 3 phase motor can be connected to run off one phase. I'd be interested to learn how this is done, How the motor actually starts and how smoothly and efficiently it runs. I love learning new stuff. I've recently discovered something called CNC. I'm going to be learning about that next.

You'd need a VFD that boosts the input voltage up to 700Vdc or so before generating the 415V 3-phase output. However, most VFDs that can accept single phase 230V inputs are of limited power rating. Put the whole thing together (single phase, 230V input and 415V output at 15kVA) and I suspect you are more likely to find rocking horse crap. Hardly surprising, as there are few obvious circumstances where high powered (industrial) equipment would not be used in an (industrial) environment with (industrial ie 3-ph) infrastructure – that's what it's for

Once you've done a bit of obligatory willy waving you should get it on ebay and then use the resulting beer tokens to buy something useful / usable. May not be worth much mind, especially if it requires a costly service. Has it been getting its annual service / safety inspection etc?

I would treat a second hand air receiver with caution, the last thing you want is it going bang. may look fine on external inspection but I would like to see inside as that is where they rust. It begs the question why are they scrapping it?

I had read that but it didn't answer why are they scrapping it.

My concerns have now been put to bed, but as you well know it is not something to be taken lightly.

To start that compressor direct on will need a substantial supply, as the plate says it is connected in delta for 415V it would be a suitable candidate for star delta starting but that is not much help without a 3 phase supply.

Seems like the best possible outcome, Oliver
