Q:Integrated wiring strength bridge spacing between the specifications which is written?

The machine is not much money, mainly the venue, such as my work in the basement of the building is an Internet cafes, the rent is .000 a year, recently renovated, as if more than .. and then the new sofa chairs and computer tables Set heard that is one thousand six, there are more than 30 computers, plus the network I guess at least 100w can operate up.

Q:Electric water and electricity master, teach how to cut into a right angle trunking ah? I'm always not sure?

RVV copper core PVC insulated PVC sheathed flexible cable, is a weak class, the general household wire for the 2-3 core, as well as multi-core for the control of electrical appliances, with copper wire for the wire, , Usually a white jacket also has a black jacket, the voltage is 300 / 500v, not a power cable, nor a control cable, belonging to the cloth wire class. I professional sales of wire and cable, there are questions you can consult

Q:Is it possible to lay the weak floor trunks with floor heating? The specific approach is? Such as title

According to your site equipment selection, reserve a few spare on it

Q:Whether the interior decoration is the first brush latex paint or the first installation of the wire (the line, with the trunking)? Please explain why

The overtravel detection switch is subject to vibration. Occasionally, the stopper is touched and the cable is tightened by the cable tie to control the shaking when moving quickly.

Q:Please the architect of the structure of the experts to answer because the beginning did not understand, in the load bearing pillars opened a slotted board, and later said that this affected the structure of security, I would like to ask you how to help remove the experts to remove the plaster, No, how to operate well.

Q:Will the wire trunking and PVC trunking in the application areas and the role of the main differences, as well as their own advantages and price comparison, etc. Thank you

This depends on your TV has no HDMI output! If there is no connection to the chicken barbecue habit of melon covered with le can not only one kind of sleep! HDMI line is blue light received TV! If your home has 5.1 speakers, then use a fiber or coaxial line from your blue light received above the amplifier! No 5.. then directly to the right channel!

Q:Just finished finishing, the wall trough cracking, very fine cracks

In the final analysis, or intelligent switch design problems, the real design of a good smart switch is not required at both ends of the lamp and then any resistance or capacitor accessories

Q:9.7.3 The same route without interference requirements of the line, can be laid in the same metal trunking. The total cross-section (including outer sheath) of the wire or cable in the trunking shall not exceed 20% of the cross-section of the trunking, and the current-carrying conductor shall not exceed 30. I would like to ask where the current-carrying wire is a single-phase circuit in the L line, not including the N and PE line is it? That is, a distribution box leads to more than 30 single-phase circuit, its current carrying wire number is the number of circuits? Is the N-wire not a current-carrying wire? More

N line must belong to the current conductor. If the three-phase load balance, N-line current is . such as imbalance, there is a current through. Such as the third harmonic of the grid serious, N-line current may be greater than the phase current. At this point, the wire cross-section should be the current flow of N line selection. PE line should be non-current-carrying conductor.

Q:Indoor wiring with a good or good PVC pipe slot? The

Meaning that the fire-resistant cross-linked 4 4 mm square power cable

Q:I ask: I open the slot, take a good line, leaving the tank and the wall mud flat, and asked the need for the proportion of cement and sand is how much? What is the degree of water What type of cement? Do not appear after the mud can not scratch the wall, drop the problem. Thank you more
