Outside electrical pvc piping

I have a 5500 watt generator that I want to hook up to my breaker box. It's a 70 foot run from the breaker box to the location on my patio.( 1.) Can I use four #10 single wires (red, black, white and green for 220 volt? (2.) What sizes electrical pvc piping would I need to run all four wires? (3.) Do home Depot carry  weather proof connectors (couplings,mips and corners) that doesn't require gluing? I know I will need a weather proof box for the generator connection outlet. Thanks

10 gauge wire is typically rated for a 30 amp load and 5500 watts works out to about 23 amps at 240v.  1/2" conduit would be fine but you'll probably find it a little easier to pull 70 feet in 3/4".  You might also want to think about if you would ever upsize your generator.  I can't say that I've looked for other fittings but PVC conduit is typically glued together.   

Please make sure you are using a proper inlet box for your connection from the generator and a disconnect switch at the panel.  If you are unsure about anything, please consult a local licensed electrician.

Hello Chuck1311.

For a 70 foot run I would definitely use 3/4" grey PVC at a minimum.  Consider using #8 wire both to minimize voltage drop, and to ensure that a larger generator in the future may be accommodated without rewiring.  This PVC is for underground use, and connections are to be glued together.  Either 4 - #8 or #10 wires should be no problem to pull through 3/4" conduit.
