These are really a good number of questions, and very VALID to give it a start in INDIA.
Hi guys I am trying to set up a mining farm in India
Welcome back to india.
and I already have over 20 Antminer S9, L3+ ready to be deployed here in India.
Good to know that you have small army ready to deploy for bitcoin mining.
Please note I am in a very remote location and I would have to order everything online.
First of all if you are planning in INDIA, forget buying everything ONLINE. Here eCom websites never check/control the product quality of third party vendors. Also i have witness myself after payment these websites leave you on your own, in case of faulty products.
So better to research offline mode as well getting products to be used for your mining farm.
Let's come to your questions, i wouldn't be able to address all your questions, but trying my level best whatever i can cover up
1) Each house here has 30 amps power and how many amps circuit would I need to upgrade to to run over 20 miners in my house? Or do I need a new meter for my new room with stronger electrical cables
1400w / 220v = 6.36 amps hope you can calculate further.
2) what is single phase vs three phase?
In India a single-phase supply is a 230V supply through two wires and 3-phase supply is 415 V supply through 4 wires and in the house the line can be divided to give 230V at individual point. The basic difference between the two is that a three-phase connection can handle heavy load while a single-phase cannot.
4) what should I do to ensure that my miners don’t suffer from power surge? Such as power surge protector but I can’t find any online?
power surge is an over/down supply of voltage from the power company that can last up to 50 microseconds. It happens a lot in INDIA. I suggest you to find a local vendor who can build you a good 20kw CVT (constant voltage transformer). Make sure they use Brass wiring into that, dont go for Aluminum wiring. Dont try to find it online, use some local source, as in case of any fault you can get service easily.
5) should I use American sockets and order everything from America? Because it’s so hard to find things here such as a power cord for my Bitmain PSU that can handle that many amps 24/7.
if you are planning to use American sockets, use converters. Else you can easily find the power cords in DELHI, especially the Nehru Palace.
6) what do you guys do to ensure proper cooling? (My locations is very humid) I will need to use a dehumidifier so I don’t get my miners rusty.
I am not sure which indian area you planning your farm. humid is everywhere. AC is the only option you may have.
7) can I use a A/C in a room that runs 24/7 when temperatures rise over certain limit?
(How would this work with a dehumidifier)
Why using both. Try using air conditioner as dehumidifier.

Very good question.
Install sound curtains or thick blankets
Install a door sweep
Use acoustic wedges panels
but still i am not much sure, if it can handle your 20 S9 monsters.
9) what India site is good for buying electrical goods online? Amazon?
I recommend, going into local market and research and buy ANCHOR or HAVELL brand.
Amazon itself is good and giant name, but the third party vendors are selling DIRT.
At last BEST OF LUCK for your mining farm.
Happy BTC mining.
