Newbie wiring question

[glenh2nd]

I hope this forum is also for us non electricians trying to do it ourselves. :roll:

I have a house built in 1957 that I just had my electrical panel upgraded. I want to add TWO Amana AC/heater units that call for 230V / 20amp plugs. I want to run the lines outside the house from the box either along the wall or buried. I prefer to use electrical PVC as it's easier to work with. Here's my questions;
1. Do I need two separate breakers or can I use one with higher amperage?
2. If I can use a single breaker what wire should I use? Should it be a bigger gauge between the electrical box and the junction/split to the two units?
3. How deep do I need to bury the wire in California?

Thank you for your time!

Glen
