What is the OSHA standard for extension cords?
The OSHA construction standard requires flexible cords to be rated for hard or extra-hard usage. These ratings are derived from the National Electrical Code, and are required to be indelibly marked approximately every foot along the length of the cord.
Why should you check outlets and extension cords?
Cords used outdoors should be checked more frequently because of the constant wear and tear. Cracked insulation or exposed wire can cause electric shock, burn, or electrical fire. Replace any damaged cords. Extension cords always conduct electricity when plugged into an outlet, even if it is not being used.
How do you inspect an extension cord?
- Inspect the cord & plug. Look for cracks or damaged insulation, loose or missing plug blades, and indications of overheating or burning, especially on the plug.
- Make sure the plug is securely attached to cable.
- Check for hot or discolored outlet wall plates.
What do extension cord colors mean?
The green wire is the ground wire, the white wire is the neutral wire, and the black wire is the hot wire. Light-duty interior extension cords often lack the ground wire, but if a ground wire is present, be sure to connect it.
What should be done with a damaged power tool or extension cord?
If a tool is defective, remove it from service, and tag it clearly “Out of service for repair”. Replace damaged equipment immediately – do not use defective tools “temporarily”. Have tools repaired by a qualified person – do not attempt field repairs.

Is it OK to daisy chain 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.
Does an extension cord use power if nothing is plugged into it?
The extension cord will not use any electricity if nothing hook up. if it is damaged, and the ground is wet, it is grounded and will lose some electricity.
Are extension cords a fire hazard?
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.
Can an extension cord be used as permanent wiring?
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.
What is the maximum number of extension cords you can connect to one another?
three
Is it illegal to run an extension cord from one house to another?
No, as long as it is not fraudulent; in other words, you must have the permission of whoever pays for the electricity you use. You also need to use safe wiring practices, which you must either know, or have somebody knowledgeable take responsibility for this.
Is it safe to run a refrigerator on an extension cord?
Using a grounded extension cord with a three-prong plug is always the best choice for major appliances including refrigerators. Extension cords with a lower gauge number—like 10 or 12 gauges—are considered heavy-duty cords because they have a higher capacity to deliver power.
Can I plug my fridge into a surge protector?
We do not recommend connecting a refrigerator or freezer to a surge protector. The compressor is sensitive to temperature and current overloads, and will shut itself down with a surge. A surge protector will override this system, and if there is a power surge, your refrigerator may not restart.
Can I run 2 refrigerators on the same circuit?
Yes you could do that, be aware though that fridges and freezers are cooled by compressors. So yes two seperate 20 Amp GFCI protected receptacles one dedicated to the freezer the other for the fridge, both separately wired to their own 20 Amp breaker.
Can I plug my fridge freezer into an extension lead?
Yes you can connect both an fridge and freezer as long as you don’t exceed 13 amps load and the extension lead is fully un wound if it’s a reel type lead.
Can you put a freezer and refrigerator on the same circuit?
A refrigerator and freezer shouldn’t be on the same circuit. Appliances like these use a lot of power intermittently, and putting too much strain on one circuit can cause frequent cooling issues, food waste, or even surges in your home.
How many amps does a freezer use UK?
Some appliances, such as lamps, televisions, computers, fridges and freezers generally require a 3 amp fuse. However washing machines, dishwashers, microwaves, kettles, toasters and irons usually require 13 amp fuses. Check out our Electrical Socket Calculator to see if you’re overloading electrical sockets at home.
Can a refrigerator be on a 15 amp circuit?
Most refrigerators run between 3 to 6 amps, with that said, a refrigerator can spike at peak usage up to 15 amps. It’s best to take into consideration worst case scenarios. You should have refrigerators and freezers installed on a 15-20 amp dedicated 120 volt circuit.
What appliances need a dedicated circuit?
Appliances that need a dedicated circuit include:
- Electric ranges.
- Wall ovens.
- Refrigerators.
- Large Microwaves.
- Freezers.
- Dishwashers.
- Garbage disposals.
- Toaster ovens.
Can I mix 12 and 14 gauge wire on a 15 amp circuit?
It is perfectly acceptable to use 12 gauge wire on a 15 amp circuit. It shouldn’t, many older homes were wired with 12 gauge throughout. Apart from that, it is actually explicitly allowed by code.
Can I put lights and outlets on the same circuit?
Basic answer to your question of can a mixture of lights and receptacles be installed on a single circuit is yes. Check with local authorities on those limitations but yes it can be done. The groundwork for all AC circuits which are wired in what is known as parallel circuitry.
How many LED lights can be on a 15 amp circuit?
Each CFL or LED bulb typically gives the same amount of light as a 60-watt incandescent bulb while drawing 10 watts or less, which is equivalent to a current draw of 1/12 amp. Thus a 15-amp circuit can safely control 180 or more fixtures that use CFL or LED bulbs.
How many LED lights can you put on a circuit?
12
How many outlets can I run on a 20-amp breaker?
10 receptacles
Is 1mm cable OK for lighting?
1mm unless exceptionly long runs or other unusuall circumstances need larger. 1mm will be run at less than half its rating in most circumstances, if we consider 1.5 to be needed for lighting, then by the same logic for a 32 amp radial we should select cable suitable for about 60 amps !
