Is it okay to plug an iron into an extension cord?
Rule two: never plug high power capacity appliances, like space heaters, refrigerators, or microwave and toaster ovens into power strips or extension cords. These appliances have higher power capacity and need to be plugged into a wall outlet directly.
What happens if you plug an extension cord into another extension cord?
DON’T plug extensions cords together. It may be tempting to just string them together, but resist the temptation. Extending the length of an extension cord by “daisy-chaining” can lead to overheating the cord by overloading it, creating a serious fire hazard.
What happens if you drop an extension cord in water?
If a live extension cord is dropped into a body of water, it can shock anyone nearby in the water. (There is greater risk in fresh water than in salt water.) People have died from this kind of situation but, interestingly, it is generally not diagnosed as electrocution.
How to splice household wiring to extend circuits?
Avoid nicking or scratching the copper wire while removing the insulation. Insert a clamp, with wires attached, into the junction box hole and from inside the box, push the included nut over the wires and onto the clamp threads. Turn the nut as far as possible onto the threads and then use a screwdriver and hammer to tap it down until it’s tight.
How many conductors are allowed in an outlet box?
When installed, the box must not be concealed inside walls or ceilings so it remains accessible at all times. By code, the total number of conductors allowed in an outlet box, known as box fill, is limited based on the box size and wire gauge.
What happens when a 120V wire comes in contact with a low voltage wire?
If an exposed conductor of a low-voltage wire comes in contact with 120v, the higher voltage can damage what- ever is at the end of the low-voltage wire. A solid connection between the exposed low-voltage wire and a 120v wire also can cause the insulation to melt and start a fire.
What do you need to know about wire splice connections?
Wire splice connections must be housed inside a covered electrical box, known as a junction box. A junction box is usually square and made of metal. When installed, the box must not be concealed inside walls or ceilings so it remains accessible at all times.
