Overall, yes. When used properly, extension leads are safe for use around the house. For added peace of mind, every extension cord you use should be manufactured and purchased from a trusted supplier. Likewise, if a lead is damaged in any way, it should not be used as this can make it a hazard.
Is it safe to connect 4 extension cords?
DON’T plug extensions cords together.
Extending the length of an extension cord by “daisy-chaining” can lead to overheating the cord by overloading it, creating a serious fire hazard.
Are multiple extension cords safe?
Some people string two extension cords together to get a lengthier one, but this is not a good idea. Extending the cords this way can lead to overheating and overloading, creating a risk for fire.
What is the safest extension cord?
Longer cords can’t handle as much current as shorter cords of the same gauge. Choose cords with polarized or three-prong plugs. For use with larger appliances, thick, round, low-gauge extension cords are best. For smaller appliances and electronics, you can use thin or flat cords.
Is it safe to use multi plug?
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.
What is the maximum number of extension cords you can connect to one another?

Is it OK to plug an extension into an extension?

How do extension cords cause fires?
Extension cords can overheat and cause fires when used improperly. Overheating is usually caused by overloading or connecting appliances that consume more watts than the cord can handle. Damaged extension cords can also cause fires. Extension cords should only be used temporarily.
Is it safe to leave an extension lead plugged in?
Extension cords are only for temporary use and are not to be left plugged into wall outlets when not being actively used. This plugs into a wall outlet and is considered a power strip even though it doesn’t have a cord. Do not plug an extension cord or power strip into it.
Why is it not safe to use an extension wire that connects to several appliances simultaneously?
Once you have two identical extension leads connected in series, one after the other, the extension cord’s resistance effectively increases. This results in greater heating of the cord and possible damage to the insulation, which can be the source of fires and electrical shock.
Which extension cord is best?
For home use, a 50-foot extension cord with a 12-gauge wire thickness offers the best in portability and power. A 12-gauge, 50-foot wire can handle 15 amps, which matches most residential breakers and many older fuses.

Is daisy-chaining extension leads safe?
With such a fire, the equipment that’s plugged into the extension will likely get damaged or permanently broken due to an electrical overload. And a fire in a building can spread quickly and become unmanageable faster than it can be contained – all because of daisy chaining.
How do I know if my extension cord is overloaded?
If any part of the extension cord is hot while in use, it is a warning sign that it may be overloaded. Check if the extension cord is properly rated for the products that are plugged into it. Also, inspect the cord along its entire length to ensure it has not been damaged.
