Generally most extension leads use cable with a CSA of 1.5mm2, however there are some leads with smaller cables in service. As a general recommendation all extension leads (unless essential) should be restricted to 5m or less in length.
Can I use 2 core cable for an extension lead?
Extension leads should only be used when it is not possible to reach a wall socket with the equipment cable. For general use, 2-core extension leads should not be used.
How do you wire up an extension lead?
Attach each section of exposed copper to the appropriate terminal screw: green wire to the green grounding screw, white (neutral) to the silver screw, and black (“hot”) to the brass screw. Wrap the wire clockwise around the terminal and tighten each screw securely.
Can you use an extension cable on an extension cable?
Considerations. While stringing together two extension cords can work as a temporary solution, such as in the case of a short power failure, it creates a significant risk when used as a long-term solution. Extended cords reduce the wattage capabilities of each cord and may lead to meltdown and fire.
What type of wire is used for outdoor extension cords?
Extension cords are rated for indoor or outdoor use. Indoor rated cords are usually 2-wire cords. Never use an indoor rated cord outdoors. Extension cords rated for outdoor are usually more durable, have 3-wires (including ground), are longer, and use larger diameter wires.
Can I plug an extension lead into an extension lead?
Only use one socket extension lead per socket and never plug an extension lead into another extension lead. This will put less strain on the wall socket. Some block adaptors do not have a fuse, which increases the risk of overloading and fire.
How many extension cables is safe?
Use only One Extension Lead Per Socket – it may sound stupid, but some people plug in an extension lead into an extension lead. Use one extension lead per socket only, otherwise the risk of overloading the wall socket and the extension lead plugged into it!
Can I make an extension cord out of Romex?
That company was taken over by Southwire, and today ROMEX® is a trademark name, like Kleenex. Because it is not very flexible, it is not generally used for extension cords, but it can be. Use the correct gauge wire for the load you plan to service with the cord.
What does 12 AWG mean on an extension cord?
16 gauge=light duty. 14 gauge=medium duty. 12 gauge=heavy duty. 10 gauge=very heavy duty. The longer the extension cord, the bigger the drop in amps.
Can I use an extension cord for my coffee maker?
Some appliances should never be connected to an extension cord. Do NOT use an extension cord with the following items: ice makers, refrigerators, microwaves, space heater, hair dryer, garbage disposals, air conditioners, toasters/toaster ovens, washers/dryers, and coffee/tea makers.
What can you plug into a 13amp extension lead?
An electric heater and a hair dryer plugged into a 13 Amp extension lead will overload it leading to risk of overheating and fire. As a general rule, no more than 3000 Watts of energy should be plugged into a 13 Amp extension lead.
How do you avoid overloading an extension lead?
You can avoid overloading sockets and risk of fire by following this simple advice: Check the current rating of the extension lead before plugging appliances into it. Most are rated at 13 A, but some are rated at only 10 A or less - the rating should be clearly marked on the back or underside of the extension lead.
Are 4 way extension leads safe?
Yes it is. You should never daisy-chain extension leads together. If you use more than one extension lead per socket it will significantly raise the risk of overloading the socket.
Why does my plug only have 2 wires?
Some appliances will only have two wires - live & neutral. These are Double Insulated and do not rely upon the earth wire for protection. The plug is wired as above but there is no earth wire to connect, however make sure that the screw on the earth terminal is not loose.
Can you use 12 2 wire as an extension cord?
Because it is not very flexible, it is not generally used for extension cords, but it can be. Use the correct gauge wire for the load you plan to service with the cord. Common gauges, in order of increasing thickness, are 14, 12 and 10. For loads of 15 amps or more, use 12-gauge or thicker.
Is it safe to make your own extension cord?
Not only can that get frustrating, but it can be dangerous as well. One way you can solve that issue is to simply make your own custom extension cord. Not only will it serve your purpose better, but it will actually be higher quality than one you can purchase at the hardware store.
