the power tool says max input 2.8 kva. do i need a 3kva transformer to run this tool or is a 3 kva transformer to big. can i buy a smaller 1 kva unit that will run the tool?

The max size transformer it is able to handle is 2.8 kva, so buy 2.7 or smaller. Definitely dont go over, it will burn your tool out.

You should get a transformer rated for a load that is larger than the actual load, so the transformer won't burn up.
3 kVA is a good start. Something even larger would be a bit better, but those things are expensive when you start talking about 5 kVA and up. If you can afford a 5 kVA step-down transformer, I would get that.

Use the 3 kva transformer. It prevents overcharges.

Yes, they will work, but not well. I have done it when no 230 volt supply was available on site. Best not let a safety officer catch you, He will be attracted by the noise and apparent poor performance of your tools. Strangely enough a SDS drill works quite well on concrete and brick, a jigsaw will work if not forced. and a circular saw turns into a deadly weapon, due to snatch. Unless you have a need for very powerfull tools, used continuously, invest in cordless tools, with a common battery size

240v is single-phase 2-pole.
110 is single-phase 1-pole.
'Max input' doesn't make any sense though - it should be 'maximum load'. If it is going to pull 2.8kva max (usually measured with a locked rotor) then you will need a 3kva to give you sufficient power.
You might want to post more details - or contact me with them, and I can try to help you (or contact the manufacturer and see if they recommend a specific transformer - or at least give you the specs to be looking for).

No u need to go bigger a 3kva should be ok normally they should take a 50% over load for a short time.

3 kva. 1 kva will burn up.

Minimum to use is a 2.8kVA transformer - and it will run hot. This is going to be a MONSTER transformer though.

2.8 is MAX input anythang larger than that MAY burn up the tool why not be safe and buy the exact replacement transformer?
