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: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 much of the cable with the switch?
The switch is selected according to the current. General switch = (2-2.5) Current three-phase current = P / 1.732 / 0.38 / 0.8 Single-phase current = P / 0.22 / 0.8
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:Apple 6 Charging Why always show this cable has not yet been certified
1 Definitions and basic tasks Communication lines and ancillary facilities Routine inspection operations are based on regional characteristics of regular light cable line inspection and protection line publicity, timely detection of problems, troubleshooting factors to ensure smooth communication; communication lines and ancillary equipment to make up Strong, to ensure that the optical cable lines and ancillary equipment integrity is good to prevent the occurrence of failure
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!
