Can I Plug a Space Heater into a Power Bar?

The question of whether it is safe to plug a space heater into a power bar has been a topic of discussion and concern for many people, especially during the winter season. According to the search results, it is generally not recommended to plug a space heater into a power strip or extension cord due to the high electrical current that space heaters draw. Plugging it into a power strip or extension cord could cause the strip or cord to overheat and potentially cause a fire.

Technical Specifications

Space Heater Power Consumption

Space heaters typically draw 11 amps or about 1,300 watts at 120v.
This high electrical current is beyond the capacity of most power strips and extension cords.

Power Strip and Extension Cord Limitations

Most power strips and extension cords are not designed to handle the high electrical current that a space heater draws.
Power strips and extension cords are not designed to handle the amp load long term and can melt if overloaded.
Overloading a power strip or extension cord can cause thermal stress, which can lead to bad connections and even worse thermal stress, causing a fire.

Safety Recommendations

Federal officials, including the Federal Emergency Management Agency (FEMA) and the National Fire Protection Association (NFPA), recommend that all space heaters be plugged into a grounded wall outlet, not an extension cord, which can overheat and catch fire.
Plugging a space heater into a power strip or extension cord could bypass the safety features of the electrical system, which is designed to detect issues with appliances.
If the space heater has any type of issues, it could cause electrical system issues in the house, which could lead to a fire hazard.

DIY Tips for Safe Space Heater Use

Manufacturer’s Instructions

Always read the manufacturer’s instructions and warnings before using a power strip or extension cord.
Ensure that the power strip or extension cord is rated for the amperage and wattage of the space heater.

Overloading Precautions

Do not overload the power strip or extension cord by plugging in too many devices.
Avoid covering the power strip or extension cord with area rugs or other items that could cause it to build up heat.

Unplugging When Not in Use

Unplug the space heater when not in use to avoid the risk of fire.

Conclusion

In summary, it is generally not recommended to plug a space heater into a power strip or extension cord due to the high electrical current that space heaters draw. Plugging it into a power strip or extension cord could cause the strip or cord to overheat and potentially cause a fire. It is best to plug space heaters directly into the wall and to pay attention to the amperage ratings and wire gauge of the power strip or extension cord and the space heater itself.
