How to choose electric tools

1.Choose qualified products with "3C" certification.

2.Generally, Class II products should be used. This type of equipment has dual insulation, making it relatively safe to use.

3.When working in damp places or places with good conductivity such as metal frames, Class II or III products should be selected.

4.When working in narrow areas such as metal containers, pipelines, boilers, etc., Class III products should be selected.

5.If it is indeed necessary to use Class I products, other measures should be taken according to the requirements, such as installing leakage protectors, isolation transformers, etc.
