Example embodiments relate to improved luminaire drivers. One embodiment includes a luminaire driver for driving a light module of a luminaire. The luminaire driver includes a driver housing. The driver housing includes a first and second power supply input connector element, for connection to an electrical distribution grid. The driver housing also includes output connector elements for connection to the light module. The luminaire driver also includes a driver circuitry arranged inside the driver housing, between the first and second power supply input connector elements and the output connector elements. The driver housing is provided with an equipotential connecting part available at an external surface of said driver housing and intended for being connected to an equipotential part of the luminaire. The luminaire driver further includes a resistive circuitry arranged inside the driver housing and connected between the equipotential connecting part and the first power supply input connector element.
