Not sure where you are located so the plugs / versions will be different but what you are looking for is a PDU.
Ok, thank you, I could not remember "pdu" and my searches weren't turning up anything useful!
I had a special line installed by an electrician: 2 pole 30 amp receptacle which has 5760 watts available.
s19 = 3250W
s15 = 1600W
So anyway, I thought I saw some forked cables around or maybe there is some kind of two prong power strip for 30amp? Do I need a pdu? Is it meant to smooth erratic power? I think I have a good steady supply.
