How many things can I plug into one power strip?
The safe number of devices you can plug into a power strip depends on the total wattage, not just the number of outlets. Most standard power strips are rated for 15 amps (1,800 watts), but you should never load them to maximum capacity for safety.
The key is understanding that it's about watts, not plugs. A power strip might have 6 outlets, but if you plug in a space heater (1,500 watts), a microwave (1,000 watts), and a coffee maker (800 watts), you've already exceeded the 1,800-watt capacity with just three devices. This creates a fire hazard and will likely trip your circuit breaker.
Safe loading guidelines suggest using no more than 80% of the power strip's capacity, which means around 1,440 watts for a 15-amp strip. To calculate your load, check the wattage on each device's label or manual. Common household items vary widely: LED light bulbs use 8-15 watts, laptops use 45-85 watts, while hair dryers can draw 1,200-1,800 watts.
High-wattage appliances should never share power strips with other devices. Space heaters, microwaves, toasters, hair dryers, and vacuum cleaners should be plugged directly into wall outlets. These devices can easily overload a power strip and create fire risks.
In New Brunswick's older homes, this becomes especially important. Many homes still have 15-amp circuits throughout, and overloading can cause nuisance tripping or dangerous overheating. TSANB regulations require proper circuit protection, and using power strips as permanent solutions for insufficient outlets violates electrical code.
Quality matters significantly when choosing power strips. Look for CSA-approved strips with built-in circuit breakers and surge protection. Cheap power strips from discount stores often lack proper internal wiring and safety features. Never daisy-chain power strips together – this multiplies fire risk and violates electrical code.
Signs you need more outlets instead of power strips include: constantly using multiple power strips, frequently tripped breakers, or needing power strips for permanent appliances. Adding proper outlets requires TSANB permits and a licensed electrician, but it's the safe, code-compliant solution.
For New Brunswick homeowners dealing with insufficient outlets, especially in older homes with knob and tube wiring, the real solution is upgrading your electrical system. Modern homes typically have outlets every 6 feet along walls, eliminating the need for multiple power strips.
