Shocking facts …

Shocking facts about DVD players and recorders.

Electrical equipment supplied by mains voltage is divided into two groups; Class I [supplied with a three core cable providing an earth connection between the electrical supply and the item of equipment. The other group, Class II [Class 2] is supplied with a two core cable, not containing an earth cable.

Within the electrical safety standards [EN 60990] it is permissible to have a leakage current of 0.5 milliamps [mA]. This may not mean much to you right now. However 3.5mA is sufficient to reduce the ability to release grip on an item held.

Once there are seven items of Class 2 equipment coupled together it is quite possible to reach the 3.5mA level, even though all electrical items comply with EN 60990.

There is a simple solution to make all Class II equipment safe; connect the outer screen of the areal cable to the Main Earth Terminal of the electrical installation. This will equalise the shock potential between Class 1 and Class 2.

I have a PDF giving more details on this subject. Please email me at;

to find out more on this subject. If in doubt, please seek the assistance of a competent Electrician.

Please let your friends and relatives know about this potential shock hazard. It may just save someone’s life.
