Hello,

we would like to have an electric sliding gate installed in our driveway. Currently, the foundations for this are being laid. The gate manufacturer specified that a NYY-J 5x1.5mm² underground cable must be installed on site.

However, when we built the house, we unfortunately laid a 15m (50 feet) long NYY-J 3x1.5mm² underground cable to the gate.

Wouldn’t that work as well? Or what is the reason for requiring a 5x instead of a 3x cable for the gate motor? I would rather not ask the gate manufacturer, as they will probably insist on 5x1.5.

Kind regards,
Tim

Or does the motor require three-phase power?

That was my initial assumption, that a single phase wouldn’t be enough. But others say that one phase is sufficient. Maybe it depends on the type of gate and motor.

When it comes to control cables, I would have expected 3x1.5mm (approximately 16 AWG) wires and the control cable to be separate, not included in the same low-voltage cable. But well, only the supplier and manufacturer know that.
