Oh, dude, the space factor is crucial for conduits because it determines how many conductors can fit inside without causing a traffic jam of wires. It's like trying to cram too many people into an elevator – not a good idea. So, you gotta make sure you have enough space for all those wires to hang out comfortably and do their thing without getting all tangled up.
Conduit bodies are used to provide pulling access in a run of conduit, to conserve space where a full size bend radius would be impractical, to allow more bends to be made in a section of conduit or to split a conduit path into multiple directions.
No, the conduit has to be supported individually from a supportive structure. The spacing of the strapping is related to the size of the conduit.
Steel conduit weighs more, provides more protection, and costs more than plastic conduit. Plastic conduit weighs less, is easier to work with, and costs less than steel conduit.
This topic is covered in the IEE's On-Site Guide, a supplement to BS 7671:2008 Regulations for Electrical Installations.'Grouping' describes to the mutual heating effect of adjacent conductors. The effect of grouping acts to reduce the number of cables actually allowed into an enclosure because, as the number of circuits increases, the current-carrying capacity of the cables reduces -requiring the use of cables with larger cross-sectional areas! And using cables with larger cross-sectional areas may then require us to use larger-diameter conduit.In practice, this might also mean distributing the cables between, say, two smaller conduits (or by using a small trunking system).Guidance in this is provided by an equation called a space factor, where:space factor = [(csa of all cables)/(internal csa of conduit)] x 100 %...where the maximum permissible space factor is 40%. In other words, the area of the cables must not exceed 40% of the internal cross-sectional area of a conduit. The 60% empty-space requirement is intended to enable the dissipation of the heat produced by the current-carrying conductors grouped inside the conduit.
A conduit connecter is a connecting piece used to connect two individual conduit units together. Conduit connecters can refer to both electrical conduits and pipe/plumbing related conduits.
Conduit fill refers to the amount of space inside a conduit that is occupied by the cables or wires running through it. It is important to adhere to conduit fill requirements to ensure proper installation, avoid overheating, and maintain compliance with electrical codes and standards. Calculating conduit fill helps determine the appropriate size of conduit needed for a specific electrical installation.

No you do not need one unless you need Conduit powered apps. A Conduit Engine is the module of Conduit Open that allows users to add apps directly to their browser without a community toolbar. It offers you an important new distribution option for your Conduit-powered offerings.

No, regular PVC glue should not be used on electrical conduit. It's important to use a solvent specifically designed for electrical conduit to ensure a secure and safe connection. Using the wrong type of glue can compromise the integrity of the conduit and pose a safety hazard.
The sizing of conduit systems that wire has to be pulled into is dependant on the physical size of the conductor being drawn into the conduit. The second governing factor is the conductor count of the specific conductor that is needed. A 500 MCM copper conductor with an insulation factor of 90 degrees C is rated at 430 amps. This is where the conductor count is need by the service, as to whether the service is single or three phase. In this specific case, the electrical code will allow both single and three phase installations to use the same size conduit. A maximum total of four 500 MCM conductors can be drawn into a 78 mm diameter conduit.
For underground conduit runs, PVC is by far the better of the two conduit systems.
The maximum degrees of bending allowed for conduit typically ranges from 90 to 360 degrees, depending on the type and size of the conduit. It is important to consult local building codes and manufacturer specifications to determine the specific maximum degrees of bending allowed for a particular conduit. Incorrect bending can cause damage to the conduit and affect the performance of the electrical system.
You can fit approximately 9 number 12 THHN wires into a half inch conduit. It's important to follow the National Electrical Code rules for conduit fill to ensure proper installation and safety.
