Home repair house how to embed PVC pipe, how to line! Mainly on the lights
4 square copper wire in the rated current carrying capacity of 25-30A. Can be connected to the maximum power of P = 1.732UI * power factor. Here the power factor is 0.8. Can be loaded with load = 1.732 * 380 * 25 * 0.8 = 13.2KW. All your power add up to less than 13.2KW, no problem. Even if you put all the load connected to a phase is also possible. Single-phase 4-square line with 5.5KW power.
Do electrical design engineer or other, see how you plan yourself
Your question I may answer that you can understand that . if it is three-phase 380V power input user, it is a zero line of a zero line, each 4 square line can be about 6 kilowatts of electrical equipment, three lines on 18 kilowatts, zero line is shared. . FireWire, zero line and ground (not three-phase 380V) is only single-phase 220V voltage line. . household appliances circuit a total of three lines, one of which is the ground wire, the other two 4 square copper wire can be the maximum load of 30A is equal to 6 kilowatts. You said all the electrical appliances and less than 4 kilowatts, you can install a 1.5P hanging air-conditioning. Not to mention all your electrical appliances are not all together at the same time, so do not reach the maximum load, rest assured with it.
To see if the cement is a woodworking board, or an iron template. If the iron template is not well embedded. Woodworking board words. Wait for the carpentry to support the bottom of the bottom mold, the bottom box fixed to the bottom of the mold lamp position. The pipe with the end of the box inside the link to stay good line. The other end of the tube to stay in the seat you want to switch on it. Line tube is best to use good quality, when the elbow to stay below the long point, inside the box inside the toilet paper, and then sealed with a transparent tape (not the toilet paper is also OK, but to seal, to prevent the time into the cement ), Wire box put a mark to do, it is best to use red paint. Tube cloth is good, with the bar wire fixed in the steel above, must not shaking, to prevent workers get the cement when the box out from the box. Cloth to more cloth a few roots, kitchen, air conditioning, lights, socket which had 9 lines, and then also cable, cable TV, all not less than 10 lines, cloth less work, generally at least two Root canal.
