indoor water and electricity installation is an important project in furniture decoration. If there is an installation problem, there may be various troublesome problems in future life, which is time-consuming, laborious and expensive, and very uneconomical. Next, I will introduce the installation steps of indoor water and electricity and the precautions for indoor water and electricity installation, hoping to help you

indoor water and electricity installation steps

1. Slotting

snap the line first, and then slotting. The pipeline slotting must be parallel and vertical lines according to the requirements. For parallel pipelines, the height shall be controlled at 60-90 cm, and the pipelines with faucets must be vertical

2. Installation

pipes are divided into cold water pipes and hot water pipes. Galvanized iron pipes should be avoided for hidden pipes. The construction personnel and the owner can discuss the water area and use function, and arrange the water and electricity master to discharge all installed taps and water positions. If there is no complete drawing, communicate with the owner to increase the use function of on-site positioning waterway

3. Inspection

waterway pipeline inspection is very important, which is related to the safety of waterway in the future. We can do pipeline inspection through pressure test. Pressure test is one of the methods to check the leakage of pipeline, and all internal wires can be blocked by plugging first. Pressure with a pressure gauge (6-8kg for home decoration) to test the water. Check all pipes and joints after pressurization

4. Waterproof

after the water pipeline is installed, seal the trunking of the toilet with cement and sand. After the trunking and the ground are dry, clean the ground and wall again. When the water on the wall and ground is dry, it can be waterproof. The wall waterproof is better to be more than 80cm high. If there is furniture on the back of the kitchen wall, the wall must be full, which can play a moisture-proof role

5. Circuit slotting

after discussing the electrical functions and requirements with the owner, disclose to the electrician and snap the parallel and vertical slotting. Then place the bottom box of the switch socket. The socket is slotted 40 cm from the ground. The hanging air conditioner socket is slotted 2.2 m from the ground, and the switch is 1.2&mdash from the ground; 1.4m slotting

6. Circuit wiring

for circuit wiring household 2.5— Copper core wire of more than 6 square meters and conduit of more than 16mm. And the strong and weak conduits should be separated from the concealed ones. The wiring of strong and weak current is required to be separated by 30 cm at the lowest limit. Air conditioning sockets are dedicated to wire grouping of more than 6 square meters, electrical sockets are dedicated to grouping of 4 square meters, and switches are dedicated to grouping of more than 2.5 square meters

precautions for indoor water and electricity installation

1. Do not operate with power on

in order to prevent electric shock, it is best to install the circuit after power failure, and do not operate with points. After installation, it is necessary to check that there is no problem before powering on the test machine. In addition to checking the relevant use performance, it is necessary to check whether the housing is charged. The electrical equipment with the housing charged cannot be used and must be repaired in time, otherwise it will cause electric shock and injury

2. Voltage calculation

before installing household appliances, you must carefully check whether the use voltage of electrical equipment is consistent with the power supply voltage. If not, it will damage the electrical equipment and cause greater losses such as fire and house. If you need to install and use, you must cooperate with the transformer. The power supply of household appliances is often provided by indoor sockets. The power sockets of household appliances should adopt two hole sockets, and the wells should be equipped with two core plugs. When installing electrical equipment, the switch should be installed in “ FireWire ”, Otherwise, when the switch is disconnected, the electrical equipment will be charged

3. The maximum load of planned power supply

the power supply line of household appliances is a circuit composed of wires connecting the power supply, electrical equipment, control and protection devices, etc. The allowable current load of the power supply line is determined by the conductor material and cross-section. The commonly used conductor materials are copper and aluminum. The current allowed by copper wire is larger than that of aluminum wire. The larger the cross-section of the conductor is, the greater the current allowed to pass

4. Understand the maximum current height

when installing electrical equipment, it is necessary to understand whether the safe carrying capacity of the power supply line can meet the use requirements, and the carrying capacity of the power supply line conductor is not less than the working current of the electrical equipment. The working current of single-phase AC 220V electrical equipment can be estimated by dividing its rated power by 220V voltage kilogram

5. Safety first

in order to ensure safety, a soldering wire should be installed at the switch in the distribution box. When the line current is too large, the soldering wire should cut off the power supply to avoid accidents and protect the safety of the line and electrical equipment. The specification of the soldering wire must meet the requirements of line protection, and cannot be arbitrarily increased, let alone replaced by other conductors

the above is the relevant knowledge about the installation steps of indoor water and electricity and the precautions for indoor water and electricity installation. Do you have a better understanding of this aspect after reading it! If you want to know more about it, please continue to pay attention to the information and look forward to more wonderful things
