Not sure where you are located so the plugs / versions will be different but what you are looking for is a PDU.

Something like this: https://www.amazon.com/Rack-Pdu-Basic-14-4KW-208V/dp/B000FLWCLE/
or this: https://www.amazon.com/Tripp-Lite-Metered-L6-20P-PDUMH20HVL66/dp/B08SZ77TFZ/

Those models are designed to be rack mounted but you get the idea.

Due to the massive power needs of miners make sure the one you get can handle the load.

For the most part you are usually better off getting dedicated runs for each miner but if you can't if the circuit can handle it you can use PDUs.
