For heavy duty appliances such as electric grills, electric ovens, electric saws, etc., heavy duty extension cords would be the most ideal. Note that not all appliances can use an extension cord. Also, not all outdoor extension cords are heavy duty. This is a common misunderstanding. Outdoor extensions are protected by plastic; rubber or Vinyl covers to prevent them from overheating due to harsh outdoor weather.
When choosing outdoor heavy duty extension cords, take note of those that are rated for chemicals, oils or extreme temperatures. These will give you extra assurance when in use. For indoor appliances, no need for such additional features.
Factors to Consider Before Buying Heavy Duty Extension Cords
Below are some distinguishing factors when finding extension cords.
Plug Type
Extension cords are either with three or two -prong plugs. However, some special application extension cords have specialty plugs and receptacles. The difference between the basic versions is that the third prong provides earthing: A path to the ground in an electrical circuit.
Earth wire reduces electrical fires and shock. Certainly, excess current gets to flow to the ground safely without passing through a human body. However, if the three slot outlets in the house are not properly grounded, the three plug extension will not add any protection.
Amperage, Cord Length & Gauge
Amperage, indicated as Amps, is the amount of current the extension cord can conduct safely. An excess of the stated amperage will lead to overheating and damage of the extension which may affect the appliance in use too. Each machine comes with indicated amperage. Matching this to the extension cord is highly advisable. Heavy Duty Extension Cords will have the highest amperage rating; typically between 16 – 20 Amps.
The cord length starts from 25 feet to 150 feet.
Gauge ranges from 10, 12, 14 and 16. 16 being light, 14 medium, 12 heavy and 10 extra heavy duty.
For example, a 12/3 cord implies a heavy gauge wire with three conductions inside.
The above features are most important when replacing an old extension cord.
