Product Description:

 EMT Compression Connector
American Standard, NPT Thread
UL Standard 514B
Size: 1/2" to 4"
Material: Zinc
Technics: Casting


EMT compression connectors are used in dry locations to bond unthreaded EMT conduit to electrical junction boxes or enclosures. TOPELE EMT compression  connectors provide concrete tight connections when taped Its steel construction maintains mechanical protection and solid grounding of the conduit to the designated electrical junction box or enclosure. They eliminate the need to thread bald conduits to attach them to electrical junction boxes or enclosures. Compression connectors are pure zinc material for excellent corrosion protection.


Applications:

EMT connector: Joins steel EMT conduit to Electrical box
•Connect & effectively bond EMT conduit to steel outlet boxes, load centers & other metal enclosures
• in concrete-tight applications when taped
•Reversible locknut designed to cut through protective coatings on boxes & enclosures
•UL standard for safety
•Application type : EMT
•Electrical Product Type : Standard Fitting
•Fitting type : Connector
•Indoor/Outdoor : Indoor / outdoor
•Paintable/Stainable : No
•Trade Size (in.) : [1/2"] [3/4"] [1"] [1-1/4"] [1-1/2"] [2"][2-1/2"] [3"] [4"]

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:How to distinguish how many pairs of cable with a large heat shrink tubing
Cable bridge grounding should belong to the protective grounding, grounding resistance at a cross point is not greater than 50 milliohms, no jumper no more than 5 milliohms
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: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: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:1000 kW 600 m cable to use much
Such a large load so far away, can only be transported with 10KY, near the installation of the transformer Caixing, if the 380V transmission, cross-sectional area, high cost, loss of large, not worthwhile. 10KV high-pressure delivery, current 55A, with 25mm² copper cable 35mm² aluminum cable delivery on it. If the 380V transmission, according to the line voltage loss simple calculation formula △ U% = PL / CS take △ U% = 5 copper cable S = PL / CS △ U% = 1000X600 / 77X5 = / 385 = 1558mm² aluminum cable S = PL / CS = U06 / 46X5 = / 230 = 2307mm² Line voltage loss △ U Simple calculation formula △ U% = PL / CS △ U% - Percentage of voltage loss P - Active power of conveying (Kw) Distance of L- M) C-constant, aluminum single-phase 8.. aluminum three-phase four-wire 46; copper single-phase 12.. copper three-phase four-wire 77S-conductor cross section (mm²) (quoted from "electrical entrance permit test low pressure Class theory "" electrical engineering basis ")
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: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:25 square copper cable how much money one meter?
3000w electrical work at 220V voltage is about 13.6A (current = power divided by voltage). Copper core line of the working current is generally a square 4-6A. That is to say you use 3-4 square power cord more secure.
Q:Is the cable head made of every building?
Generally have every building floor wiring closet must be connected to the big cable. The big cable comes in to do the cable head
