Design installation must be calculated
From the beginning of the design installation, the cross-section of the conductor must be calculated and selected so that it is capable of carrying the current to the power consuming devices it supplies.
The connection points to the branch circuit at the two ends of the hot and source wires must not overlap, when the tape wrapping of the wire connection points is dry and burnt, it must be checked immediately and the connection points must be tightened.
The conductors, fuses, and circuit breakers must not be rusted, if rusted, the rusted place is the place where the heat is generated and can easily catch fire when overloaded, and must be replaced.
Overlapping the conductors can easily lead to the risk of fire and explosion
The fuse wire must meet the standard
Check the installation of the main circuit breaker or circuit breaker for the main power line in the house and for each sub-power line, each room and each high-capacity electrical device. Protective devices must be placed in front of each electrical outlet, the fuse wire must meet the standards and be suitable for the capacity used, ensuring that when an electrical short circuit occurs, the fuse wire must explode, cutting off the power source immediately.
Do not use aluminum foil or other unsuitable metal wires to replace damaged fuse wires, circuit breakers, and circuit breakers. Install a voltage stabilizer to avoid fire and explosion due to overcurrent or overvoltage.
Turn off all electrical equipment when leaving the house
Before leaving the house, turn off all consuming devices, electrical appliances, and before going to bed, check equipment and appliances such as lights and fans. Turn off the power to unnecessary devices.
Do not use water to extinguish fires before cutting off the power
