What are electrical sleeves used for?
In the electrical industry there are many different types of sleeves used. There are insulation sleeves, linesman's high voltage sleeves and conduit sleeves to name a few. The insulation sleeve is used for the protection of electrical conductors. Linesman's sleeves are used for extensions to the protective rubber gauntlets that they wear when working on high tension wiring systems. Conduit sleeves are used when a broken conduit needs to be repaired in situ.

How many bends in a conduit run would be required before the use of a pull box?
There has to be a pull box between every four quarter bends in a conduit run.
How many current carrying conductors are allowed in a raceway before derating?
You can put three ccc's in a conduit (any size conduit) before you derate. Keep in mind that for single phase loads (lighting, receptacles) the neutral is also counted as a current carrying conductor. This derating factor does not apply to nipples 24 inches long or less. See NEC Table 310.15(B)(2)(a) for full details on derating regarding ccc's.

Why stranded wires are twisted?
Stranded conductors are made up of many smaller solid conductors. In order to bunch the solid conductors to make the stranded wire they have to be held together. The simplest way of doing this is to twist them together. Once the solid wires are twisted together they are drawn through a machine that applies the insulation coating which holds the solid wires together. The final result is a insulated stranded conductor that has good flexibility. With this flexibility multiple stranded conductors can be easily be drawn through conduit systems that incorporate up to four 90 degree bends between junction boxes.
How many number 12 THHN conductors are allowed in half inch EMT?
According to the 2005 NEC Annex C, table C.1 you are allowed nine #12 THHN conductors in a 1/2" trade size EMT conduit. If your conduit run is any length at all, you would be wise to increase the conduit size to 3/4". as pulling 9 #12's for any length in 1/2" EMT is very difficult.

Can you use existing PVC conduit run from basement to 8th floor for 120v circuits for chillers?
The simple answer to your question is yes. But there are limits to how many wires can be in any conduit, and the current carrying capacity of the conductors can be affected by distance, ambient temperature, and how many conductors are contained in the same conduit. Other things to consider are, Can you physically fit the wires in there? Would it be easier to run a new conduit? Do you have the manpower necessary to get the work done?

How many wires can be sent in one inch conduit?
The electrical code book provides a chart for conduit fill. The same size conductors have different types and thickness's of insulation which has to be taken into account on wire fill calculations. 1" or 27 mm conduit can carry the following amount of RW90 insulated conductors.25 - #14, 19 - #12, 14 - #10, 7 - #8, 10 - #6, 4 - #4, 3 - #3, 3 - #2,and 1 - #1.
