How are electrical conductors placed in a conduit?
A: Electrical conductors are placed inside a conduit by pulling them through the conduit by the use of a wire specially made for that purpose. The pull wire is first pushed through the empty conduit from one end, the total bends in the conduit must not add up to greater than 360 degrees between pull boxes, and then the wires are fastened to the end of the pull wire. When the electrical wire is large other but similar methods are used.
How to pull wires through conduit?
If the conduit is fairly straight you can usually just shove the wires through. Bend a small tight hook on the ends so the end of each wire can get past any rough spots in the pipe. For longer pulls, or if you have more than 2 90 degree bends we usually use a “fish tape” or pull cord. Best way I have found to get a pull cord started is to make a little parachute with a plastic bag and tie that to your pull cord. Then vacuum it through the pipe. If you are pulling big wires you made need to start with a string and use it to pull in a “mule tape” or nylon pull cord and then pull your wires.
How to snake wire through flex?
If you need to snake wire through a section of flex in between two sections of conduit you can probably take off one end of the flex and get the wires or the snake on through. Remember you are only allowed to have 360 degrees of angles (say, 4 90’s or 4 45 degree bends and 2 90 deg. bends) between pull points, so you may be ahead to put in a junction box or condolet at one end of the flex.

How to lay conduit on a wall?
To get conduit to lay flat against a wall around the outside of a corner you need a fitting called an “LB” (short for an “L that goes back”. There are also “LR” and “LL” fittings according to how the conduit connects in relation to the cap. But an LB works best in most cases.). There is also a corner pull point fitting. These LBs and corner fittings have a little oval cover so you can open them and pull the wire through, and then feed the wire the other direction. They also serve as a pull-point in case you have more than 4 90-degree bends on your pipe, (by code, you are only allowed 360 degrees of total bends in between pull points; so 4 90’s or 3 90’s and 3 more 30 degree offsets, or any combination that adds up to 360. Usually it is a good idea to only pull around 3 90’s—especially if you don’t do this all the time. You can add a Junction Box or a “straight Condolet” for additional pull points.)

What is conduit connector?
Conduit always terminates at some type of electrical box or at fixed equipment that also serves as a box. Special connectors are used to secure conduit to boxes and to join lengths of conduit together to form long straight runs or bends. The boxes, connectors, and conduit form a wire enclosure system called a raceway.
What type of wire is used in conduit?
The types of wire most commonly installed inside of conduit are THHN and THWN. THHN/THWN wires are individual, insulated, and color-coded wires. They are similar to the wires you see when you strip the outer sheathing off of NM cable.
What is conduit used for?
Special connectors are used to secure conduits to boxes and to join lengths of conduits together to form long straight runs or bends. The boxes, connectors, and conduits form a wire enclosure system called a raceway. A raceway is an enclosed conduit that forms a physical pathway for the electrical wiring to follow. In this way, the metal raceway acts in place of the grounding wire that is found in non-metallic cable. (This is also the main reason why only metal boxes may be used with metal conduit.)
What is EMT conduit?
EMT: Electrical metallic conduit is rigid, thin-walled metal conduit typically made of galvanized steel. Because it is thin-walled and lightweight, it is easy to bend with a special tool called a conduit bender, and it cannot be threaded like a heavier conduit.

What type of wire is used for PVC conduit?
Use THHN With PVC Conduit. THHN (thermoplastic high heat-resistant nylon-coated) is the best wire for pulling through PVC conduit. Other types of wire have a sticky rubber sheathing that makes them almost impossible to pull. Stranded THHN is used on most commercial jobs—it’s more flexible than solid wire, which makes it easier to pull, ...
How to deburr PVC conduit?
Deburr PVC Conduit with a Utility Knife. If you do end up with a rough edge when you cut PVC conduit, don’t forget to deburr the inside of the cut edge. Burrs can damage the insulation on the wires. There are a lot of fancy deburring tools available, but it’s just as easy to spin a utility knife on the inside of the conduit to smooth it out.
