6Surge protectors (SPDs) are important lines of defense for electrical equipment against lightning strikes, power grid fluctuations and transient overvoltages. As a professional provider of surge protector, we regularly receive inquiries from customers: "Can all devices be connected directly after purchasing a surge protector?" In fact, while surge protectors provide effective protection for most electronic devices, not all appliances are suitable for connecting to standard surge protector sockets. Incorrect usage can not only affect the protective effect, but also cause safety hazards. This article will show you which devices are not suitable for connecting to a surge protector and how to use them correctly to help you make the most of them.

1.High-Power Electric Heating Equipment
For example:
Electric Heaters
Electric kettle
Induction cookers
Ovens
Electric fan heaters
Reason:
Excessive power easily exceeds the surge protector's rated load.
This can lead to overheating, tripping and even fire risks.
2.Refrigeration Equipment
For example:
Fridge
Chill box
Air-conditioners
Reason:
The compressor produces a large starting current.
Some anti-surge outlets are not suitable for long-term handling of this type of surge load.
3. Electric Motor Equipment
For example:
Air compressor
Pumps
Industrial motor
Large vacuum cleaners
Reason:
High startup current can shorten the lifespan of SPD or Socket.
4. Medical Life Support Equipment
For example:
Domestic ventilators
Oxygen concentrators (must refer to manufacturer's instructions)
Medical monitoring equipment
Reason:
Surge protectors shouldn't be the sole source of power.
Power supply shall be provided according to the medical equipment manufacturer's requirements.

V. Multi-stage Series Sockets
For example:
Surge saver connected to surge protector
Power strip plugged in;
Reason:
Increased contact resistance and risk of overheating.
It could affect protection.
6.UPS (in some cases)
Example:
UPS connects after passing certain breakers
Reason:
Some UPS manufacturers explicitly require straight-wall socket connections.
May lead to false alarms or malfunctions.
