Can the advanced cutting board prevent electric spark?

Many people use the wire to see the electric spark that comes out of the socket.So can the price of your cutting board prevent electric sparks?The answer is: no!Can!!!!The electric spark is based on the fact that when the shrapnel in the plug and the socket is very close, the resulting electric field strikes the air, causing the discharge to occur.The way to reduce this situation is not by a function of the line, but rather:

1. Before the plug is inserted into the jack, check whether the electrical switch is OFF.

2. Buy a more and more switch board, which will be cut off before inserting.

3. The large brand cutting board should choose the socket copper sleeve for good workmanship and high flatness. The higher the flatness, the less likely it is to generate electric spark.
