Product Description:

Service Entrance Cap
1 Material: Aluminum
2 Type: Threaded type or Clamp type
3 Size: 1/2 inch—4inch
4 Apply: connecting EMT conduit / IMC conduit
Field Names: Service entrance caps, weather heads, service entrance heads, service entrance kits,
cobra heads, weather caps, utility service caps, meter heads, service heads.

Application:

These service entrance caps attach to the end of plain EMT conduits that are being used to bring over-head
power to buildings or homes. Their clamp-on design and large insulator yoke allows the cables from meers to be hung outside of service heads without the fear of abrasion while waiting fro the utility power connections. 1/2" to 4" sizes are available.

Q:How to solve the computer connected to the TV audio problem, how to set the computer and TV audio separation
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:The difference between nylon balls and geese and ducks
As long as the cable is thick enough, 20 meters of the basic loss can be ignored.
Q:1000 kW 600 m cable to use much
Depends on the load is emotional, resistive, should be too long cable, consider the pressure drop. Generally consider 2.5 or more.
Q:5 air conditioning can be used 4 square cable
Lengthened low voltage side, the line resistance increases, the voltage drop increases. Reduced load capacity. So that the router due to insufficient supply voltage and can not work properly. It is not allowed to use 9V power supply. Voltage is too high, the router part of the internal power supply increased power, heat increased, it is possible to burn the router. It is necessary to extend the power cord, I suggest you extend the power supply side (220V one end) safe and reliable. Increase the voltage to increase the supply current, in the electrical working voltage range (with the electrical work voltage range) is allowed, too low electrical appliances can not work properly. Too high there is the risk of burning appliances, according to your actual situation, marked 5V0.2A that the router works at rated voltage, so the way to improve the supply voltage is not applicable. So you can only improve the power supply power (that is, you say to increase the power supply current rather than voltage). With the reserve power, it will provide enough current at the rated voltage (the router as a resistor, from I = U / R, you can know the danger of increasing the voltage) need help please message
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:7 kilowatts of electricity with what specifications of the wire
If it is connected to the 220V of the electricity above the 6 square of the copper line can be
Q:What is the type of pipe that is marked as KBG pipe?
The best cement and other dry in the closing, because the wet cement contains moisture, can be conductive, dry the probability of conduction less. Pay attention to the wire to maintain integrity, no broken skin, it is best to protect the casing.
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).
Q:Decoration doubt, what kind of wall can not open the horizontal groove?
Reply to the landlord: I read a part of the literature, more Google is aware of the following part may be your reference weak construction specifications 1
Q:How to distinguish how many pairs of cable with a large heat shrink tubing
Yellow line is video, red and white are audio, you can only pick one!
