3.In this forum, I have seen most of them mentioning about 1 phase.
4.What are the advantages of 1 phase over 3 phase?
5.Is 2.5 sq mm sufficient for 3 hp motor at 700 depth?

Thanks for your valuable feedback,

Hi,

I'm also looking for submersible installation but for 2hp single phase. I heard from electrician for 2hp and higher better to go for 4 sq mm.

Thanks Raju,

Yeah I'm going with 4 sqmm, and also I found out that its better to go for 3-phase instead of 1-phase as 1-phase motor will vibrate more and will bear the burnt of itseems.
