This 6-way power extension cable is rated at 230V AC and is earthed. All the sockets on the extension cable accept 3-pin earthed plugs. The extension cable also splits the earthing, as it requires a mains socket designed to accept 3-pin earthed plugs. The mains extension cable is equipped with a switch that enables you to switch all connected units on or off by pressing a single button. This enables you to save power instead of having the equipment on standby. Note: Only works with Danish earth connector.
