I bought a differential switch (brand ABB), 40 A, for 2.530 Baht ./. 30%.
The owner of the shop said to me that they are very expensive, I answered her that in the case of an accident you start paying a lot more (when one gets a shock or, which is very common in Thailand, your house starts burning down), but they don’t care a lot about what can happen to-morrow as long as it is a cheap installation.
In Thailand it’s very common that the zero is functioning like an earth and they are connected together.
Every year, many people are injured in electrical accidents
at home. Not everyone knows that many of these injuries
could be prevented by having RCD protection installed in the
house‘s consumer unit.
RCD protection can save lives by protecting you and your
family from fatal electric shocks, and can also provide some
protection against fire.
RCDs switch off the electricity in a fraction of a second if you get an electric shock. Having a
modern consumer unit fitted with RCDs gives you the best protection because they usually
cover all the wiring, sockets and appliances in your home.
The aims of this ABB technical guide are to raise general awareness of electrical safety and
encourage householders with older electrical installations to upgrade to a modern consumer
unit with built-in RCDs.
