Conduit Cable Capacity

Centaur conduit is light in weight (16% of weight of steel conduit), is clean and easy to handle, does not require the use of on site special equipment such as vice bender or thread cutting gear, is non-conductive, will not corrode or stain plaster.
Centaur conduit, oval conduit and high impact channelling should be installed using the special Centaur accessories.

Oval conduit and high impact channel are usually used for short runs in domestic situations, for external fixing or where the deep chasing required for round conduit is not possible. uPVC conduit has a rate of expansion greater than that of steel; it is therefore important to make sure that surface work allows for sliding joint into boxes or couplers, this will permit movement along the conduit run and avoid distortion. The distance between saddles or clips should not exceed 4’ 0’ (1.20 m). If possible the boxes should be fixed first and a line used to establish correct alignment, which will ease the threading of cable through the conduit. Cutting can be performed with any fine-toothed saw. Bending or forming of conduit of 25 mm Dia. or less can be achieved cold, provided the appropriate bending spring is employed internally in the location of the bend. Greater diameters may need local application of gentle heat. Cable is threaded by using the Centaur draw tape. Centaur plastic conduit cement provides a waterproof joint which is easily made by painting the female internal surface of any joint before sliding the male section in with a twisting action to spread the cement evenly.

Conduit Cable Capacity Small Table

Table 12A. Cable factors short straight runs
Single-core PVC insulated cables in straight runs of conduit exceeding 3m in length or in runs of any length incorporating bends or sets. The information in the tables is intended only for guidance.
Calculation system based on Appendix 12 IEE Wiring Regulations.
1. Use table 12A or 12C to determine the factor for each cable being used.
2. Add the appropriate cable factors and compare with the conduit factor from table 12B or 12D.
3. The required conduit size is the one having a factor equal to or greater than the sum of the cable factors.
