Most audio-visual equipment (such as televisions, DVDs, satellite receivers, Freeview set top boxes, game consoles, radio tuners, audio amplifiers, surround sound systems, aerial distribution amplifiers) relies upon double insulation for electrical safety and has no separate earth wire. However, this equipment does have a small amount of electrical leakage. With a few pieces of equipment this is not dangerous and is acceptable under law. The Code of Practice, issued to members, states that this safety connection need only be made if more than seven pieces of equipment are interconnected throughout the house. A certificate should be issued whether this connection has been made or not to explain the issue and inform the customer that the connection has been made, or advise that it should be made if more equipment is added. |
