Electric situation<\/p>\n
Whilst a couple of recent letters have addressed a concern
\n(whether founded or not) about the effects of electro magnetic
\nfields from high voltage transmission lines may I comment on a
\nfar more dangerous electrical situation that is ignored daily?<\/p>\n
I'm talking about the practice of producing metal framed
\nelectrical appliances without an earth conductor. This is
\ncontrary to all rulings, including the Indonesian Electrical
\nWiring Rulebook, and yet the shops are full of washing machines,
\nrefrigerators, pressure pumps and voltage regulators with only a
\ntwo wire supply cable.<\/p>\n
It is interesting to note that most of the items are of Japan
\norigin, if not manufacture. Perhaps this helps explain their
\nhealthy balance of payments, as every metal framed appliance that
\nis produced without an earth connection saves the manufacturer
\nthe cost of the additional conductor in the mains cable (a 50
\npercent increase in mains cable cost) plus the additional pin on
\nthe molded plug and the crimp connection and termination point on
\nthe appliance itself.<\/p>\n
A fault of active wire to frame on these types of appliances
\nleaves the user as the return path to ground for the fault
\ncurrent. Great for the manufacturers' budgets but not too good
\nfor the consumers' bodies. Maybe the manufacturers feel that the
\nconsumer has only to invert the appliance plug in the wall socket
\nand the fault then becomes neutral to frame, no more shock. It's
\nall too easy, isn't it?<\/p>\n
If the manufacturers and the inspecting authorities are not
\nprepared to exercise any responsibility maybe there is a consumer
\ngroup out there that could take up the issue?<\/p>\n
