An electrical assembly includes a DC tap including first and second tap terminals that are respectively connectable to first and second DC power transmission media, the DC tap including a tap limb extending between the first and second tap terminals and having two limb portions separated by a third tap terminal connectable to an electrical load, each tap limb portion including a DC blocking capacitor. The assembly further includes a current return configured to electrically interconnect the or each AC terminal to the third tap terminal, a converter unit, and a controller configured to selectively control the converter unit to generate at least one first non-fundamental frequency alternating current component at the or each AC terminal and modify the or each first non-fundamental frequency alternating current component to enable the DC tap to draw power from the DC electrical network for supply to the electrical load.
