high-voltage connection

A high-voltage connection is a direct cable supplying at least 1,000 volts from an alternating current (AC) electrical grid.

The connection is a direct cable from an AC grid. The stated threshold is at least 1,000 volts, so both the voltage and the alternating-current supply are part of this definition.

A power source located entirely within the property does not itself establish a cable connection to the grid. Likewise, a lower-voltage grid connection does not meet the threshold stated here.
