"I have been an electrician for 30 years and I have seen too many owners who regret it after renovations! "Master Wang took a sip of wine and finally told the inside story of the industry. Today, let us unveil the six most common taboos in home decoration wire construction and help you save tens of thousands of yuan in rework costs!
Taboo 1: Strong and weak electricity are in the same tube and tank
"I just handled a case last week. The TV at the owner's house always had snowflakes and the Internet was intermittent. "Master Wang shook his head. The reason is that in order to save trouble during decoration, the network cable and wires were worn in the same tube. Correct practice:
The distance between strong and weak electric tubes is ≥ 30 cm
Wrap the intersections with tinfoil
The network cable must use Class 6 shielded wires
Taboo 2: Right angle turn of line pipe
"The most irritating thing is that some masters make the wire pipes into a 90-degree right angle for their appearance! "Master Wang slapped the table and said. Measured data:
The success rate of line change in the late stage of right-angle bending is less than 10%
Large arc bend (radius of curvature ≥ 6D) line replacement success rate 100%
It is recommended to use spring pipe bender for on-site processing
Taboo 3: Do not handle the terminals
"Last year's fire was caused by loose joints and sparks. "Master Wang said seriously. Must be done:
Adopt WAGO terminal
Or standardize hot and tin treatment
Black tape is absolutely prohibited!
Taboo 4: Tubing filling rate exceeds the standard
"Some construction sites have 8 wires plugged into one 20 pipes. It's a ticking time bomb! "Standard requirements:
No more than 3 threads should be threaded in a single tube
Utilization rate of cross-sectional area of line tube ≤ 40%
Reserve live line space
Taboo 5: Ignore ground protection
"Nine out of ten owners don't understand. It will be too late to get an electric shock! "Key inspections:
Ground resistance of distribution box ≤ 4 Ω
All sockets must be connected to PE wires
Test with phase detector
Taboo 6: Water and electricity are in the same tank
"The most dangerous thing is this! "Master Wang said excitedly:
Water pipes and wires must be laid in grooves
Spacing ≥ 10 cm
Water pipes down and wires up
[Three tests must be done for acceptance]
Use a megohmmeter to measure insulation resistance ≥ 0.5M Ω
Test all socket phases after power up
Individual loop test of high-power electrical appliances
Master Wang finally warned: "Don't pay hundreds of thousands of yuan for decoration just to save thousands of yuan in wages! Find a certified electrician and carry out construction according to the specifications. You can't save money! "
