Description:
EMT steel couplings are used to connect the ends of two unthreaded EMT conduits together. EMT steel set-screw couplings provide concrete tight connections when taped. Additionally, these set-screw couplings eliminate the need to thread bald conduits to fit old threaded couplings. EMT steel couplings are steel and with zinc-plate surface for excellent corrosion protection in damp location.

Q: Is the cable head made of every building?: Building in accordance with the floor or unit configuration distribution box, there are office buildings using a total box. Where there is a cable out of the situation, must be wrapped to make the cable head, according to the choice of distribution box circuit breaker wiring crimp or not crimp the cable terminal. In other words, the cable head must be made, but not necessarily crimp the cable terminal.

Q: What is the meaning of PG + digital markings for electrical wiring?: Will the general power cable control cable can do the largest square...

Q: How much of the cable with the switch?: Switch = (2-2.5) current three-phase current = P / 1.732 / 0.38 / 0.8 single-phase current = P / 0.22 / 0.8

Q: Does anyone know the "line buckle" classification (including shape / size / material / has been some commonly used size!) Line deduction is a hardware products! For daily necessities!: In accordance with the relevant safety regulations, the power cable should not be parallel to the top of the thermal pipe laying, when can not be avoided, the interval distance should not be less than 1000mm, during which should also take effective insulation measures. Power cable and thermal pipe cross, the thermal pipe insulation layer, the separation distance should be not less than 500mm, no insulation layer should not be less than 1000mm, and in the cross with the insulation board to be protected, the length of the insulation board should not be less than d + 2000mm (d for the thermal pipe insulation layer diameter).

Q: Can the main cable be aluminum cable? And explain why, thank you!: Power board problem cost 10 less than the general maintenance received you 150

Q: 5 air conditioning can be used 4 square cable: Such as the extension line added to the adapter primary (city side) certainly easy to use. Extended by two meters, the router does not start, may be extended wire diameter is too thin, bold wire try. If not, choose 6V2A adapter try, the voltage is too high will burn the router. Increase the current is no problem, just like the computer's power, 300-watt power can be replaced, and small is not OK.

Q: The difference between nylon balls and geese and ducks: If the 2.5 square copper wire for the output extension cable, 20 meters distance, the total resistance of about 2 * 1.7 * 0.2 / 2.5 = 0.272 (ohms), the current maximum 1.8A, the voltage drop is 0.272 * 1.8 = ), The charging voltage is 55-0.5 = 54.5 (volts), a difference of about 1% will not have any impact on the battery. However, the third floor, said Ye Hao, you can put the charger put the debris room, from your house put a 220V power cord down, home and then engage in a switch control. It is best to design a light at home, can intuitively see if the electricity is full. That's better. Design light, teach you a way: to find a bad leakless protector, open there is a coil-like ring-shaped stuff, called zero sequence current transformer, it will be down, be careful, do not put Transformers inside the coil hurt, get down, in the transformer two thin lines connected to a light-emitting diode. And then your 220V power cord line of fire from the center of the sensor through, around 3-5 turns. In this way, as long as there is current flow, the light-emitting diode will be bright, when the charge is over, the charging current is close to zero, the light-emitting diode will be extinguished. You can from the light-emitting diode is lit to determine whether the electric has been filled. I also have an electric bike that is so charged.

Q: How do I ask for cable prices? How many tons is one or more?: Yellow line is video, red and white are audio, you can only pick one!

Q: 6 square cable up to how many air conditioning (1.5P): 7 kilowatts of electricity with what specifications of the wire if it is single-phase 220V, then 7 kilowatts of current is 7000 × 220V = 31.8A, check the electrical manual 4 square copper wire interception is 33A, to meet the requirements.

Q: 25 square copper cable how much money one meter?: There is no 1..2..4.5 square wire. The family uses most of the four wires with 1.. 1.. 2.5 and 4. Power 1KW Approx. 5A.3KW Approx. 15A.2.5 square copper wire can be used. Plug or empty open (25A).
