"...a 10000v circuit..."
Would you please double check this number for accuracy? That doesn't make sense.
Please include more information about why you are asking this question...

Im trying to find out If its possible to run a 220v 7.7amp pump of a two pole breaker which is already running a 220v 33. Amp well pump?

I meant 23amp well pump

So you want to add a 7.7 amp pump to a circuit with a 23 amp pump already on it?
What size is the circuit breaker? What size are the existing conductors? Copper?
What is this for? A pool? A well?

To be within the electrical code you should check the pump manufacturer's installation instructions for any limitations or requirements for operation.
