For power cables it will depend on the specific setup your new Building uses.
For example this is the one we recommend in the US for 2000W power supplies.
And this would have the wall socket of NEMA 6-15P
You should check your power supply also. On a 2000W power supply it runs only on 208+Volts.
Also note the Gage of the wire 14 AWG is important (to thin of a wire may get hot).
Feel free to contact ‘firstname.lastname@example.org’ and ask about it.
