Electrical Safety in the case of the Extension LeadsCan it be dangerous to use the extension leads? The use of extension leads can present the following dangers:
- tripping or falling;
- cable damage due to wear, particularly where leads are walked over, flexed at a single point or stored badly;
- when the leads are fitted to the power tools, they can become tangled and one of the conductors may eventually fail, which could cause danger;
- a greater capacity for overloading circuits, which increases the risk of fire;
- Only use an extension lead which was bought ready assembled(don't try to assemble your own "extension lead");
- It is recommended that no extension lead be more than 15 metres in length;
- Only use extension leads fitted with suitably-insulated connectors and plugs. Never be tempted to join two lengths of flex by twisting the bared ends of wires together, even if you bind them with insulating tape;
- The extension lead should be positioned carefully to prevent any risk of damage to the cable;
- If the cable has to cross a pathway/a place where people walk, the risk of tripping and damage can be minimized by covering it with a rubber protector strip;
- Always check that the leads, the plugs and the sockets are undamaged;
- Always check that the extension lead plug contains a correctly-rated fuse for the equipment to be used;
- When a cable drum extension lead is in use, the cable must be completely unwound from the drum to avoid the cable overheating;
- Check that the cable has an earth wire if feeding Class I (metal-cored equipment). 2-core extension leads should not be used.
Electrical Safety in the case of the AdaptorsMulti-way adapters should not normally be used. If two appliances are regularly used from one power point, replace it with a double socket if possible
when an adapter is used with a number of plugs, the angle and weight of the assembly increases the stress on the socket contacts. There is also a danger of electrical overload as the combined loads may exceed the ratings of the socket-outlet. When circumstances require more connection points, a multi-way trailing socket with minimum cable length should be used, though care should be taken not to overload the unit.
