I think you should use 240 line instead of 220.

Re: 220 volt
This thread had been temporarily moved to an area accessible only to the Moderators. This action was taken because it appeared to be an attempt by a Do It Yourself person to obtain "how-to" information.
In an exchange of Private Messages, the Original Poster has provided assurances that this is not the case. In this case, the OP stated that he intends only to dig a trench and to lay the conduit, and has arranged for an electrician to complete the project. Therefore, the thread is being returned to the active area. I offer an apology to the OP for the inconvenience and the delay.

Re: 220 volt
In order to know what size wire is needed, you first must know the total load. You can get this information in terms of amps or (preferably) in terms of power (watts or VA). The manufacturer or sales office from which you bought the hot tub should be able to tell you that.
Once you know the load, and can pick the wire size, you then can decide what size of conduit is needed.
But your best bet is to ask your electrician for the conduit size and for the burial depth. The electrician has to answer to the Authority Having Jurisdiction (AHJ) for the proper installation of this project, and will therefore have to give you the correct information. In other words, the electrician will not be allowed to wire the tub, if the branch circuit to the tub does not meet code.

Re: 220 volt
breezer4,
I realize that you probably feel you will save a significant cost by doing the labor work yourself and I understand that. However, when I wired my home and put in my service, I decided to replace the overhead lines and go underground. I figured I'd do the same as you and save some money by digging the trench to my pole myself. Mind you, my pole was 100' from my house but nonetheless I was a glutten for punishment. Anyway, I found out later that for $.50/ft. the contractor I hired would have doug the trench for me. Man, the value of the time it took me to dig the trench by hand far exceeded the $50.00 he would have charged.

Re: 220 volt
Let me add that at a previous (rental) house, I needed to have a trench dug for about 100 feet, at least 2 feet deep, in order to allow for cable TV and a second phone line to be installed. This was a very old house that only had one poor quality phone connection, and the previous tenant used satellite TV.
I decided to dig the trench myself. Like Bob, I regretted it afterwards. I also decided not to spring for the cost of a trench digging machine, but did it by hand. I regretted it afterwards also.

I was lucky. I got scared of the 750 feet trench prior to start digging it myself. And it was a cold winter time with a frozen ground.
