• Latching RCD (sometimes called passive) – when the power is lost due to an earth fault, the RCD trips out and isolates the circuit it is protecting. Latching RCD’s do not trip during power cuts so they are great for fridges and freezers and also for protecting remote/unmanned areas. This would also make them ideal for protecting some heating equipment set to “frost protection”, fish tanks, battery charging, and the protection of remote or unmanned areas.

How RCDs work:

• RCDs work on the principle "What goes in must come out". They operate by continuously comparing the current flow in both the active (supply) and neutral (return) conductors of an electrical circuit. If the current flow becomes sufficiently unbalanced, some of the current in the active conductor is not returning through the neutral conductor and is leaking to earth.

Examples of equipment recommended to be protected by an RCD:

• Hand held electric power tools, such as drills, saws and similar equipment.
• Tools such as jack-hammers, electric lawn mowers.
• Equipment on construction sites.
• Equipment such as appliances which move while in operation, such as vacuum cleaners and floor polishers.
• Appliances in wet areas such as kitchens, including kettles, jugs, frying pans, portable urns, food mixers/blenders.
• Hand held appliances such as hair dryers, curling wands, electric knives, etc.
• Cord extension leads.
