I would like to ask experienced professionals: is it necessary to have a qualified company to handle the high and low voltage power distribution for supplying power to frequency-conversion pumps with a capacity of over 700 kW?

Is it necessary to engage a specialized electrical design firm for the power distribution system? What qualifications should the suppliers and installers have in this regard?
It depends on the voltage level: if it’s 380V, your own electricians can handle the wiring. If it’s 6000V or higher, it’s best to ask a company affiliated with the electricity utility to carry out the design and wiring work for you. We installed two air compressors with a capacity of 700 KW and a voltage of 10,000 volts; we asked the electricity utility company to handle the design, installation, and wiring.
Thank you for the answer. It must be high pressure; it seems I need to find a specialized design firm first.
