First question is, what does the 20Amps derated mean to 30amps PDU's?
I am looking to see if I can run 4 rigs on a 30amp PDU from my Dryer connection. I live in an apartment and I have no other of changing anything, so I'm sacrificing my washer and dryer, I can do laundromats.

It depends on the PDU - a few are "continuous rated" in which case they will probably be listed as "24 amp", most are not in which case a 30 amp unit should be derated to that 24 amps.

The drier circuit is ITSELF probably a 30 amp circuit, in which case you would have to derate to 24 amps continuous usage ANYWAY.

If your rigs eat 1320 watts "at the wall" or less, you should be fine with 4 of them.
If your voltage at the outlet is higher than 220 volts, you can go proportionally higher on the wattage per rig safely.

Very well clarified, so you saying I can run 4 rigs if I pull 1320W from the wall, I truly was hoping to run 4 rigs off this one dryer outlet, so I can have run for expansion cos I see my incinerator runs on a 20Amps breaker but only rated for 5.6Amps, thinking of running an extension cord from the other outlet its plugged into.

Each rig running right now pulls 1050 and 980 respectively, still plan on dropping down the power draw on the 1050 one, letting it run because it gives me 204mh/s with 1150/2020 core/mem with 1500 straps and top at 110W, will revisit the rig and see if I can trade 10W on each card that's 70W for 1mh/s, 7 total, will bring the rig down to 197.

Should be able to run *5* rigs if they are only pulling 1050 watts each.

Extension cords to run a miner = VERY BAD idea, even the heavy-duty ones tend to heat up a lot at the connections.

I have had clients that ran huge grow ops in Bell Air and would run 10 gauge extension cords throughout - I think the lights only pulled like 1200 watts or something each.

I did a couple tours through some of these mansions and I still can't believe or understand how they would get away with gutting these multi million dollar homes. Rent was 25k-30k on some of these homes and they didn't even hire an electrician to wire things... people amaze me.

Long story short, heavy duty extension cords do work. Probably not the smartest thing to do, but I had these clients for about 8 years doing their financials and they didn't burn down a single house. Luckily.
