Hello if a PDU is rated for 20A at 220v and each rig is pulling say 9 amps then you can only run 2 rigs on 1 PDU before it trips?
Maybe
But a 9 amp rig is a beast. So is it like a 10 gpu rig ?
9 x 220 is about 1980 watts.
But 220 in the USA can run up to 240. So. 9 x 240 is 2160 watts.
So your rigs could get 1980 to 2160 watts as your volts vary.
I run 238 to 243 volts year round
6 x 1070 GTX FTW cards with 2 power supplies pulls 9.1A and 1100 watts on a 120v/15a circuit using the kill a watt meter
I have a 30a circuit and 60a circuit and would like to switch the rigs to run on those but lower priced PDUs mostly only do 20A so I was confused what you guys are doing to run many rigs on one pdu
okay a 30amp pdu like this
http://www.ebay.com/itm/Genuine-HP-EO4501-Server-Power-Distribution-Module-228481-002/232449268221?
has 4 sockets
it is rated at 24 amps internally to protect your 30 amp circuit breaker. that complies with the 80% derating. it is a cheap price for good used gear
it can run 4 of these psu's at 1300 watt draw each
http://www.parallelminer.com/product/2400-watt-power-supply-kit-for-gpu-mining-94-efficiency-200-240v-up-to-24-gpu/
buy 4 of these
https://www.monoprice.com/product?p_id=24206
buy 4 of these pico psu's
https://bitcointalksearch.org/topic/m.20802414
this setup above will do 4x 1300 watt rigs safely on a 30 amp 220/240 breaker with an l6-30r
http://www.ebay.com/itm/Pass-Seymour-locking-receptacle-L6-30R-MADE-IN-U-S-A-30-amp-250V-twist-lock-/390917364485?
and the 30 amp circuit breaker for 240 volts needs to use 10 gauge wire to that l6-30r
cost for all above is about
50-60 pdu
420 psu's oh use code slush for 5% off
20 power cords
10 l6-30r
100 for the pico psu's
about 600 bucks to run 24 gpus on four 6 card rigs.
don't cheap out all the shit above works is tested and should work for years.

You should keep your power draw at or below 80% of the max rating of the PDU output. Technically, you could run more than that, however, they are not meant to sustain those loads without creating a heat problem.
I have a number of circuits at 80% (~16A @ 120V) and the metal conduit for the wiring gets really warm to the touch.
