2. Refrigerator: Due to their high power consumption and frequent on/off cycles, refrigerators can quickly overload a power strip and result in damage. Refrigerators need a wall outlet that is only used to power them, just like ovens do.
3. Washing Machine: Washing machines use a lot of energy when they are turned on. This is the primary justification for not putting these appliances in the same outlet as any other device or appliance.
The maximum power that most washing machines can use is 1400 watts, which is perilously near to the maximum load that most power strips can handle.
Additionally, washing machines are frequently left unattended while functioning for longer periods of time—at least an hour—which is sufficient for a power strip to overheat.
4. Heating: Since most portable heaters utilize 1,500 watts of electricity on their high setting and typically run for long periods of time, they should never be connected to a power strip.
5. Microwave: Most microwave ovens are plugged into their own outlet because they require a lot of electricity, which is always a good idea.
