An electrical inverter comprises first and second supply lines, which in use are connected to the positive and negative terminals of a d.c. supply. An inverting network is connected between the supply lines and has output terminals for connection to the load. A current sensing device is provided in one of the supply lines and is operable when the current flow in the supply line exceeds a predetermined value, to stop current flowing in the load for a predetermined period of time.
