Electrical Conduits / Armored Cables

09/24/2010 4:01 PM

Hi, I need to know what is the difference between a conduit and a duct. What is a duct bank? Can a duct bank be directly buried? In which applications are armored cables used? Can these armored cables pass in conduits/ducts? In outdoor lighting, how are cables laid? If we have a generator inside a soundproof canopy, how will the cables between the canopy and the generator panel (inside the building) be routed? (suppose that there is a distance of 5 meters between the generator and the building). I Appreciate your prompt answer. Thanks.

Methinks you are in over your head, my friend.

Now that you've posed all these different questions, what are you really trying to accomplish?

Are you setting up an outdoor music venue?

Well, this strays from the current pattern.

Nine sentences. Six questions. Two pieces of information: "...a distance of 5 meters..." and it is probably outside... outside where we do not know, but it is probably outside.

Rule 75:

"Signalmen must change duty only at the appointed time.

Each Signalman being relieved must inform the Signalman relieving him whether the electrical instruments, signals, points &c., are in good working order, what trains, if any, are in the sections, or are signalled, and of any other matter necessary to enable the man taking duty to properly discharge his duties.

The relieving Signalman before taking duty must, as far as practicable, satisfy himself that he as received all information in regard to the matters referred to above.

A Signalman leaving duty after giving all necessary information to the man relieving him must leave the signal box without delay.

Each Signalman must enter in the Train Register the time of his arrival on duty and the time of his leaving and place his signature thereto.

A Signalman opening a signal box must, as soon as possible, satisfy himself that the electrical instruments, signals, points &c., are in proper working order."

- British Railways Rule Book 1950 as amended to 1st October 1961.

we try to help you,..but you must check again with your electric engineer near your recident. And then change your topic, become : (please help, my Electric Project)

1.a conduit is a steel pipe that cable run inside, a duct is like a tunnel, you can make from a metal sheet that you make like a long cube, and you install above the celling or it can be also duct bank that you make from a concrete that installed below the road. the purpose is to protect cable from the pressure of heavy vehicle that moving through that road.

2. Armored cable is cable rounded by an armored. no need armored cable if you use conduits and ducts(if the duct is sheet metal and placed above the celling). if the duct means duct bank below the road, you still use armored cable, because the duct bank is not long(ussually for crossing the road) and then cables are run inside the cable trench (pit digged along)

3. Outdor Lighting, how many cables are laid ? is depend of quantity, configuration and wattage and voltage of your lightings,for example : 10 pcs lamps, 220V, 100 watt,you can use 1 cable (4cores, R,S,T,N), 2.5 mm^2, from one lighting JB to another Lighting JB.and then 1 cable 2 core, 1.5mm^2, from each JB to each lamp.

4. How many cable be routed from Genset ? its also depend on what loads will be supplied by a genset. wheter genset only feed One Panel.after from that panel, there are out going cables to many loads.

warm regards
