So why is it tripping? What should I do when it trips?
First of all, we need to know that under normal circumstances, home tripping is divided into two types: air switch tripping and leakage switch tripping. Different switches have different tripping reasons and different solutions.
So, how to distinguish between air switch and leakage switch?
Simply put, the one with leakage protection is called leakage switch (referred to as “leakage protection”), and the one without leakage protection is an ordinary air switch (referred to as “air switch”, which is often used as the main switch).
In terms of appearance, the air switch is larger and is often used for general power control or lighting circuit control, while the leakage switch is relatively small. More importantly, the leakage switch has a leakage test button, while the air switch does not.
After talking about the difference, let’s get to the point. Today we will talk about the problem of air switch tripping.
Air switches usually have two major functions, namely short circuit protection and overload protection. There is also an optional function, that is, undervoltage (voltage is too low) or overvoltage (voltage is too high) protection, these two need to be specially selected.
So, what are the main reasons for the tripping of the air switch?
1. Short circuit trip: The air switch has a short circuit protection function, so when the air switch detects a short circuit in the circuit, in order to protect the safety of the line, the air switch will trip for protection. Because the current is very large when a short circuit occurs, and the voltage is very small at this time, it usually trips when a short circuit occurs. There are two types of short-circuit tripping: line short-circuit and electrical short-circuit, but no matter what the reason is, do not solve the short-circuit problem easily by yourself. It is recommended to find a professional electrician to solve it to avoid danger.
The main reasons for short-circuit tripping are:
1). Line short circuit: wrong wiring, wire aging and loss of insulation ability, lightning strike, wire quality problems, etc. will cause short circuit tripping.
Solution: try to find a professional to arrange the wires and choose wires with excellent performance.
2). Electrical short-circuit: If the electrical appliance itself fails, it will also cause the current to increase and a short-circuit trip will occur.
Solution: Have a professional find the faulty appliance for repair.
2. Overload trip: When the load current in the line exceeds the safe current of the line, the air switch will trip in order to protect the safety of the line. Generally, the overload protection will continue to trip after closing for a period of time, ranging from several seconds to several hours, and the specific time is related to the current of the line.
