GB/T 4706.103-2024 Safety of household and similar electrical appliances - Part 103 : Particular requirements for electric fishing machines
1 Scope
This clause of GB/T 4706.1-2024 is replaced by the following.
This standard specifies the safety requirements for electric fishing machines by means of which water may be electrified for the purpose of catching fish or for providing barriers to all animals living in water.
The rated voltage of electric fishing machines is not more than 250 V for single phase machines and 480 V for other machines, except that the rated voltage of electric fishing machines for permanent connection to fixed wiring is not more than 1000 V.
Electric fishing machines are appliances for scientific and commercial use.
Additional requirements for boat mounted electric fishing machines are given in Annex AA.
Note 101: Examples of electric fishing machines coming within the scope of this standard are:
- mains-operated electric fishing machines which include those supplied from portable or stationary generator sets;
- battery-operated electric fishing machines.
Note 102: Attention is drawn to the fact that
- for appliances intended to be used on board ships or boats, additional requirements can be necessary;
- in many countries, additional requirements may be specified by the national management authorities.
Note 103: This standard does not apply to
- electric fence energizers (GB/T 4706.91);
- electric animal stunning equipment (GB/T 4706.97);
- shark deterrent devices that are carried by the user.
