There is described a servicing connection for connecting an electrical device to a supply outlet, wherein live and neutral contacts of the supply outlet are isolated from live and neutral contacts of the device, but a connection is maintained between earth contacts of the supply and the device. The connection may be embodied as an adaptor for interposition between a conventional supply outlet and a conventional power inlet of the device, or may be in the form of a power inlet capable of receiving a supply cord in alternative "servicing" and "operation" positions. There is also described a connection in the form of a power cord for use with a conventional power inlet, and having an additional connector engageable with the power inlet to make an earth connection only.
