1.If that no-fuse breaker is suddenly disconnected and fuses melt to disconnect, as
often happens, ask professional technicians to check and repair them.
2.When not using electrical appliances, turn off at the source of electricity, leaving
then the spot so as safe.
3.If electrical wires unfortunately have a short circuit, cut off the source of
electricity immediately. Before the source of electricity is cut off, do not use water
for extinction, so as not to cause electrical conduction.
4.Do not tie up extension wires or over-long electricity wires (this will probably cause
fire because of storing up heat). Also do not use electricity surpassing the proper
load.
5.Check at any time whether electricity wires have any damage.
6.The plug of the electrical appliance should be tightly plugged in. If it is loose,
high heat and sparks can possibly result.
