Thats strange, my message disppeared.

Anyway I will have to write it again. Is it possible to tell if you have got triple phase power by looking at the meter in the meter box? There is nothing that says what phase it is, but it does say 3x230V/400V on the meter but not much else . It also has a diagram of 3 circuits, plus a 4th. It also has a day and night meter.

The description sounds more like the meter capability than the system you have installed.
Best way to check is to count how many wires come into the meter box. Do you have a photo?

Looks pretty standard to me, are you renting a place? or sharing power costs with another unit? If so, just looks like a way to tell how much you've used.

Although to be sure, check your garage or shed and see if there is a large power point in there for industrial machinery...if not, then you won't have it

It is on a farm building, and it was supposed to have it installed. It was initially just connected to a bore and an irrigation system, but both of those a pretty low power users. I might have to check with the power company as they should probably know.

Sorry, I meant do you have a photo of the wiring.
The meter is definitely 3 phase capable, but may not be fully utilised.
Your main incoming cable should contain at least 3 wires, 4 if the neutral is included. There may also be a pilot wire installed, so up to 5 individual wires in total.

I have now got a photo of behind the meter board. The big central wire coming up is the main feed from the road, and this has red, white, blue and black wires. The red, white an blue, then feed into the main switch on the meterboard. Not sure if that is enough info to tell if it is 3 phase power. The power company didn't know, but they believed it was single phase connection from their records without seeing it. If it was single phase, I wouldn't have thought the main feed would have 4 wires.
