This is typically engraved on the cord. Once you have identified the gauge of the cord on your equipment, you will need an extension cord that is at least one grade lower. One grade lower will mean that the extension cord is thicker and will be able to provide adequate power to your machine. In some cases, you may need to choose an even lower gauge.
For example, many burnishers have a 14 gauge cord and will require a 12 gauge industrial electrical extension cord. The 12 gauge electrical extension cord will allow the electricity to flow freely for longer distances. The capacity of the cord to power your janitorial equipment will also be affected by the length of the extension cord. The longer the extension cord, the farther the power has to travel. Increased length decreases the total amps getting to the machine, creating strain on the outlet and the machine.
You should use the shortest extension cord possible that will reach where the operator is trying to go. In most cases, the extension cord should never be the same length as the power cord.
Extension cords have resistance. Longer wires mean more resistance and less power getting through to your equipment. Extension cords that do not provide adequate power will starve your machine of the correct amount of electricity. Longer extension cords will decrease the life of the motor on your cleaning equipment, as it causes them to work much harder to draw the electricity to the unit.
It also depends on your soil type— if it's sandy and easy to dig, save money by digging deep you won't need to use metal conduit. Keep your extension cord plugs inside it and the container will protect them from the wet and humid weather. Method: 2 Take a good quality plastic bag. Cover the whole extension power cord and wire together.
Make a bunch and place them at your choice of place. Occasionally, instead of being buried directly in the ground, an underground cable is placed in a tunnel, which can be 20 or 30 metres below ground.
A 12 gauge wire is typically good for 15 amp at feet. The plug end is easier to dry out than the socket end… get out your blow-dryer and set it to high and blow the end that got wet for a while. As Tester says, extension cords are not meant for permanent wiring. But there are a number of things to keep in mind when you are using extension cords. Keep extension cords away from water. Do not over-extend your extension cords.
Keep your extension cords cool. Extension cords are NOT permanent solutions for power. Use bright color extension cords to avoid hazards. Using extension cords properly is critical to your safety. With continuous use over time, an extension cord can rapidly deteriorate, creating a potentially dangerous electric shock or fire hazard. Do not substitute extension cords for permanent wiring. Do not run through walls, doorways, ceilings or floors.
Can I run extension cord feet? As you can see, there are many factors to consider beyond the reality of the extension cord. Many times, the user doesn't heed the extension cord size compared to the length of the run. They just grab any and all sizes of extension cords and put them together to get to the work at hand.
Long runs of wire encounter a variable that you may not have considered, resistance. Even though the copper wire is a very good conductor, it does have some resistance that causes heat. Heat does damage, not only to the extension cord itself, but also the power tools connected to them. The voltage drop that occurs can heat up the motors of the tools that are attached to them. If you've ever burnt up a drill while using it in the series of examples we have provided, you now know what not to do.
When you power up a tool like a drill and it runs slower than normal, it should now give you a warning sign of voltage drop and cause you to stop before ruining the tool. Most times, having a good, heavy extension cord or two to get to the area you need power can solve that problem. Never run long runs of undersized extension cords and power heavy-load equipment like sump pumps, compressors, etc.
The longer the run of wire, the more resistance, and thus, more heat. So how does this affect you? Well, power tools draw a certain amount of amperage to run both correctly and efficiently.
