Extension Power Cords FAQ

What is the difference between a power cord and an extension cord?

A power cord is a cable that connects an electrical device directly to a power source, such as a wall outlet. An extension cord, on the other hand, is used to extend the reach of a power cord, allowing you to plug devices into outlets that are farther away. Extension cords have a male connector on one end and a female connector on the other, enabling you to connect your device's power cord to the extension cord and then to the wall outlet.

Are power extension cords safe?

Power extension cords can be safe when used properly and according to safety guidelines. However, they can pose a fire hazard if overloaded or used incorrectly. Always ensure that your extension cord is UL, cUL, or CSA approved and rated for the intended load. Never daisy-chain multiple extension cords together, and avoid running them under carpets, through walls, or in areas where they may become pinched or damaged.

What is the rule for extension cords?

According to OSHA standards, the maximum length for an extension cord is 100 feet. Any worksite requiring a longer extension must use a temporary power distribution box. Additionally, extension cords are intended for temporary use only, up to a maximum of 90 days. Using them as permanent wiring is a fire hazard and violates safety regulations.

How much power can I run through an extension cord?

The amount of power an extension cord can safely handle depends on its wire gauge. Thicker cords with lower gauge numbers (e.g., 12 or 14 AWG) can carry more current and are suitable for high-wattage appliances, while thinner cords with higher gauge numbers (e.g., 16 or 18 AWG) are better for low-wattage devices. Always check the cord's amperage and wattage ratings to ensure it can handle the load of your connected devices.

What should I look for when buying an extension cord?

When purchasing an extension cord, consider the following factors:

• Buy a cord longer than you think you'll need to avoid excessive stretching.
• Choose a thicker gauge (lower number) for high-power applications.
• Look for cords rated for at least 15 amps to handle most household appliances.
• For outdoor use, select weather-resistant cords with insulation that can withstand moisture and temperature changes.
• Opt for cords with polarized or grounded plugs for added safety.

Is it safe to have a power strip on your bed?

No, it is not safe to have a power strip or extension cord on your bed. Power strips and extension cords should never be placed under mattresses, carpets, or in any location where they may become crushed or overheated. This can lead to a serious fire hazard. Always keep power strips and extension cords in open, well-ventilated areas.

Are thicker extension cords safer?

Yes, generally speaking, thicker extension cords are safer than thinner ones. Thicker cords have a lower wire gauge (e.g., 12 AWG or 14 AWG) and can handle higher currents and wattages without overheating or posing a fire risk. Thinner cords with higher gauges (e.g., 16 AWG or 18 AWG) are more suitable for low-power devices and should not be used for high-wattage appliances.
