Ms. Shen lived in the Hougang House built in the early 1980s. She said: "The plug is not in the bathroom and will not be wet. All of our power switch (Power Points) is connected to the distribution disk box. This is very good.. If anything happens, the circuit breaker will stick. "
However, experts said that this may still be unsafe.Chan Chee Hin, an electrical engineer holding an electrical license, pointed out that the water heater uses a power socket instead of Double Pole Switch, and there will still be electric shock risk.
An expert witness at the Energy Market Authority pointed out in the research news of the autopsy court last week that if the bipolar switches of the independent circuit can be used to reduce the risk of the melting of the wire, the tragedy of a family of three electric shocks in the House of Jurong Lake will not happen.Essence
When the Energy Market Administration replied to the "Today’s Daily" inquiry, it is recommended that the homeowner purchase a water heater with a safe logo and ensure that it does not use a three -pin plug."During the installation process, make sure that the electric water heater is connected to a separate power supply and has its dedicated water heater switch. The water heater should not be connected to the socket on the wall or extended the line, because its power load is high and there is a danger of electric shock."
Regardless of whether RCCB is aware of security risks, considering costs, some residents say that they will not change unless the water heater fails.
Chan CHEE HIN said that the owner sometimes tries to reduce the cost by installing the water heater by himself, or requires the contractor to use the general power socket to power the water heater.
He emphasized that the properly installed water heater should be directly obtained from the power distribution box of the home, controlled by a bipolar water heater switch, and was protected by an effective RCCB.
He said that if the contractor connects the water heater to the nearby circuit, they can save the cost of cable, wire grooves and labor, and may save 150 to 300 yuan.
